How to Photograph Flowers -- Part I
How to Photograph Flowers -- Part I
Article and Photography by Ron Bigelow
www.ronbigelow.com
There are few subjects that draw photographers as much as
flowers. Why shouldn’t it be so? After all, flowers seem to offer the
photographer so much: striking hues, graceful curves, and dramatic
color contrast. It’s no wonder that so many people photograph flowers.
Furthermore, it all seems so easy – just point the camera at one of the beautiful blooms and release the shutter. Unfortunately, the images that result often do not depict the beauty that the eye perceived. The reality is that it is easy to get a picture of a flower; it is not so easy to create an image that portrays the elegance, beauty, and intricate detail that the flower displays.
Like any other area of photography, creating flower images that rise above the ordinary requires knowledge and skill. However, once mastered, the knowledge and skill will lead to dramatic flower images.
This three part article series covers both the technical and artistic aspects of flower photography. Part I of the series covers the technical aspects while Part II and Part III cover the artistic. Now, one might be tempted to think of the technical aspects as boring and want to bypass them in order to go straight to the fun, artistic stuff. This would be a mistake. The technical aspects form the foundation for the artistic work. Without a firm understanding of the basics of equipment; light; white balance; exposure; and wind, the artistic efforts are likely to result in disappointing flower images.
So, in order to create powerful flower images, one must first become a skilled technician (Part I), then, a creative artist (Part II and Part III).
Tripod: A tripod is essential for flower photography. Often, the light during flower photography is fairly low. This occurs for a couple of reasons. First, flowers are often found in areas of shade (such as the forest). Second, low light levels (such as an overcast sky) often produce the best flower images. Consequently, slower shutter speeds are often required to compensate for the low light levels. In addition, for closer flower shots, smaller apertures will be required (unless a very shallow depth of field is desired). The smaller apertures will require slower shutter speeds. A tripod will allow the use of slower shutter speeds without the blurring that will occur if the camera is hand held (blurring due to wind will be covered later).

Equipment
In addition to a good camera, several pieces of equipment will make photographing flowers more enjoyable and successful.Tripod: A tripod is essential for flower photography. Often, the light during flower photography is fairly low. This occurs for a couple of reasons. First, flowers are often found in areas of shade (such as the forest). Second, low light levels (such as an overcast sky) often produce the best flower images. Consequently, slower shutter speeds are often required to compensate for the low light levels. In addition, for closer flower shots, smaller apertures will be required (unless a very shallow depth of field is desired). The smaller apertures will require slower shutter speeds. A tripod will allow the use of slower shutter speeds without the blurring that will occur if the camera is hand held (blurring due to wind will be covered later).

Figure 2: Tripod with Center Column Reversed
If much walking or hiking is expected, the tripod weight will become an issue. This results in a problem. Heavy tripods are sturdy, but they are tiring to carry around all day. Light tripods are easy to carry, but many are not very steady. One solution is to use a carbon fiber tripod. Carbon fiber tripods are both sturdy and fairly light weight. The down side is the cost. Carbon fiber tripods are much more expensive than aluminum tripods.
Last, it is preferable to use a tripod that has three section legs. Four section legs allow the tripod to be collapsed to a shorter length, but they are less sturdy than three section legs.
Figure 3: Tripod Head
Of course, the ballhead needs to be sturdy enough to support the weight of the camera and lens. This is particularly true when a longer lens is used.
Lenses: To make the most of a flower
excursion, a few lenses will be needed. To capture a field of flowers, a
wide angle lens will be needed. A normal lens will be required for
those times when a smaller group of flowers are being photographed.
Telephoto lenses can be used when it is necessary to compress distances
(e.g., to make flowers appear close together). Of course, an
alternative is to use a zoom lens that covers all the focal lengths that
might be required.
However, sooner or later, most serious flower photographers want to move in close. This requires some special equipment. Four of the most common approaches to photographing close-up are:
An extension tube fits between the lens and the camera body. An extension tube is essentially a hollow tube that contains no lens elements. An extension tube moves the lens farther from the sensor; this allows the lens to focus closer. The advantages of an extension tube are that it is inexpensive, is small and light weight, and will not degrade image quality. The disadvantage of an extension tube is that it will decrease the amount of light that reaches the sensor.
A teleconverter is similar to an extension tube in that it fits between the lens and the camera. However, a teleconverter does contain lens elements. A teleconvertor increases the focal length of a lens, but it does not change the minimum focus distance. This results in an increase in magnification. The advantages of a teleconverter are that it is less expensive than a lens (but more expensive than a close-up lens or an extension tube), is relatively small and light weight, and causes little or no image degradation (at least the high quality ones don’t). The downside is that a teleconverter will decrease the amount of light that reaches the sensor (usually resulting in a one or two stop light lose).
While close-up lenses, extension tubes, and teleconverters get
the job done, the gold standard for close-up work is the macro lens (see
Figure 4). A macro lens is a highly corrected lens that is designed to
focus very close to the subject. Many macro lenses create a life size
(1:1) image on the sensor. However, some specialty macro lenses can
focus even closer. The advantage of a macro lens is the very high
quality images that it creates. The disadvantages are that a macro lens
is larger and heavier than the previously covered options. In
addition, a macro lens is generally expensive (a good macro lens can
easily cost over $1,000).
One thing to keep in mind when considering a macro lens is that a macro lens around 150mm to 200mm is generally preferred to a shorter macro lens for two reasons. First, a longer macro lens provides more working distance between the lens and the subject. This is particularly important if subjects, such as shy bugs, will be photographed in addition to flowers. Second, a longer macro lens has a shallower depth of field which makes it easier to blur the background so that the background does not distract from the subject.
Shutter Release: Just because a camera is on a tripod doesn't mean that the camera will be steady. The simple act of releasing the shutter can cause vibrations that will cause a loss of sharpness. One problem is that pressing the shutter almost ensures that a certain amount of vibration will be transmitted to the camera. The solution is simple. The shutter needs to be released without the photographer touching the camera at the time of the shutter release.

Polarizer: A polarizer
can improve flower images in a couple of ways. First, polarizers can
help reduce glare. Second, polarizers can improve the saturation of the
flowers and the surrounding environment.

Figure 7: Diffuser
Light
One of the most important factors in creating great flower images is the light. Without the proper lighting conditions, it will be very difficult to get impressive looking flower shots.Light has four main properties:
- Quality
- Color
- Saturation
- Direction
Soft light is a very diffused and flattering light. Soft light has low contrast. The bright areas and shadow areas tend to blend together easily. The transitions between sunlight and shadow tend to be gradual.
Soft light usually has decent shadow detail. This is due to the fact that soft light has a smaller dynamic range than hard light. Under soft light conditions, a photographer has a good chance of capturing the entire dynamic range of the scene.
In addition to the gentile blending of light and shadow and more manageable dynamic range, soft light usually produces more saturated colors than hard light.
Soft light is created by a large or filtered light source. A hazy or cloudy sky will produce soft light. This is one of the reasons that cloudy or even rainy days are good for flower photography. Light reflected off of a surface (e.g., a white reflector) often becomes soft. Light that is filtered by a lot of atmosphere is soft.
Figure 8: Flower Shot in Soft Light
Hard light is a very direct, harsh, and often unflattering light. Hard light has a very high contrast, and the transitions between light and shadow are usually rather abrupt.
Hard light often lacks shadow detail. This lack of shadow detail is related to the large dynamic range of hard light. In hard light conditions, either the highlights or shadows may lose detail when photographed.
Figure 9: Flower Shot in Hard Light
By now, it should be obvious that soft light is highly desirable for most flower photography.
Color: Visible light is composed of a
mixture of colors. Neutral light is composed of an equal amount of each
of these colors. However, light is not always neutral. Often, the color
balance of the light has been altered. Most frequently, this occurs
because one or more of the colors have been, at least partially,
filtered out of the light. When this happens, the color of the light
changes. Because of this, the light is constantly changing color all
day long, and this affects the color balance of images that are taken.
This is an issue because color affects the mood of an image. Consequently, the color of the light that illuminates a scene will impact the mood of the image and its ability to impart what the photographer wanted to communicate to the viewer of the image. This works to great advantage for the knowledgeable photographer that uses knowledge of light color to capture images where the color of the light is in harmony with the mood that the photographer wishes to create in the image. Conversely, the light often works to the detriment of the less knowledgeable photographer to contradict the mood that was intended.
Luckily, the color of light can be simplified down to three basic categories of color: neutral light (no strong hue), warm light (tinted with yellow, orange, and red), and cool light (tinted with blue). We can simplify color down to these three categories because each of these categories has a different effect on how people respond to an image.
Neutral light, which has no strong hue, is best used when a photographer wants the natural color of the objects to shine forth. Neutral light is found away from both ends of the day (neither in very early morning nor in late afternoon). Light from a direct, overhead sun on a clear day may have a fairly neutral color.
Photographers that wish to use neutral light need to beware of certain conditions. Heavy cloud cover will likely shift the color of the light toward blue. Also, shadows generally have a bluish hue. Light that is filtered or reflected in any way may pick up a hue. For instance, a photographer standing in a forest will, likely, find that the light has picked up a green hue from the leaves overhead. A photographer in a canyon with light reflected off the canyon walls will likely find that the light has picked up a color from the walls (probably a warm tone).
Warm light is good for creating inviting, dreamy moods in an image. People tend to associate warm light with feelings of comfort, friendship, and romance. Warm light is best found just after sunrise or just before sunset.

Warm light is good for creating inviting, dreamy moods in an image. People tend to associate warm light with feelings of comfort, friendship, and romance. Warm light is best found just after sunrise or just before sunset.
Cool light is good for creating feelings of calm or cold.
People tend to think of deep, calm lakes as being blue. A calm sky is
usually blue. On the other hand, people also associate blue with cold:
ice may have a blue hue as does the light of an early, winter morning.
Cool light can often be found in the time between the first light of day and sunrise as well as between sunset and darkness. These twilight times often cast a soft, dim, bluish light over the terrain. Blue light can also be found under cloudy skies and in shadows.
For the photographer, the issue becomes one of matching the color of the light to the mood that the photographer wishes to create.
Saturation: The next aspect of color
that is important to the photographer is saturation. From the
photographer's point of view, saturation refers to the intensity of the
color. A color that is very vivid is a saturated color (see Figure 10).
Cool light can often be found in the time between the first light of day and sunrise as well as between sunset and darkness. These twilight times often cast a soft, dim, bluish light over the terrain. Blue light can also be found under cloudy skies and in shadows.
For the photographer, the issue becomes one of matching the color of the light to the mood that the photographer wishes to create.
Figure 10: Saturated Colors
Figure 11: Unsaturated Colors
Since color affects the mood and impact of an image, saturation becomes important. Often, photographers want rich, saturated colors. Therefore, photographers need to understand what factors can be used to control saturation.
One of the biggest factors that affects saturation is the time of day. Early morning and late afternoon generally provide more saturated colors than mid-day.
A polarizer filter is another way that can be used, in many situations, to increase the saturation of colors. Part of the light that dilutes saturation is polarized light. A polarizer can reduce the amount of polarized light and improve the saturation of the colors. However, a polarizer is not equally effective under all circumstances. A polarizer has the greatest affect when the camera is pointed at right angles (perpendicular) to the direction of the sunlight.
Direction: The last characteristic of
light is direction. Specifically, it is the direction of the light with
respect to the direction of the line from the camera to the object
being photographed. There are three primary directions of light: front,
side, and back. Each of these directions of light has its own
characteristics and has an impact on the mood that an image projects.
Frontlight hits images head on (from the front or overhead). It is less used in good flower photography and more frequently used in bad. Frontlighting is often found mid day. At that time, the sun is overhead and tends to hit objects in a rather direct manner.
Sidelight is low angle light that hits objects from the side. It can be a very dramatic light.
Frontlight hits images head on (from the front or overhead). It is less used in good flower photography and more frequently used in bad. Frontlighting is often found mid day. At that time, the sun is overhead and tends to hit objects in a rather direct manner.
Sidelight is low angle light that hits objects from the side. It can be a very dramatic light.
Sidelight is great for those times when a photographer wants to
emphasize texture or shape. Sidelight also has an interesting affect on
shadows; it causes the shadows to become very long. In some cases,
these elongated shadows can be used to add drama or emphasize a
flower's shape. In other cases, the shadows themselves become the
center of interest.
Sidelight occurs when the sun is low on the horizon. This means that photographers can take advantage of sidelight early in the morning or late in the afternoon. Figure 12 shows an example of sidelight.
Backlight hits objects from behind so that the light is shining toward the camera lens.
Sidelight occurs when the sun is low on the horizon. This means that photographers can take advantage of sidelight early in the morning or late in the afternoon. Figure 12 shows an example of sidelight.
Figure 12: Sidelight
Figure 13: Backlighting
Backlighting is great for creating images with a touch of the dramatic. In the case of silhouettes, form often takes on more importance than detail.
Like sidelight, backlight usually occurs when the sun is low on the horizon, but backlight has the additional restriction that the light must be shining toward the camera. This can cause a couple of problems for photographers. First, light shining into the lens can create flair. This occurs when some of the light bounces around between the lens or filter elements. If the camera has a filter on it, removing the filter may reduce the flair. Second, the large dynamic range of backlit scenes may prevent the photographer from capturing detail in parts of the scene where detail is desired. In this case, the photographer may resort to one of the many methods used to handle large dynamic ranges (e.g., fill flash or digital blending of images taken at different exposures).
Okay, so how can all this information about light be put together? Probably, the best way is to look at some different types of light
Overcast Light: Overcast light is great for flower photography.
- Quality: The light is very soft.
- Color: The light will tend to be blue. This is great when photographing bluish flowers. It is a problem when photographing warm toned flowers. When shooting warm toned flowers in overcast light, a white balance preset or manual white balance will need to be used in order to prevent a bluish color cast in the image.
- Saturation: The saturation should be excellent.
- Direction: The light seems to come from everywhere, so there is no real directionality.
Just after Sunrise or Just before Sunset: This light often tends to be very good for warm toned flowers.
- Quality: The light is very soft.
- Color: The light will tend to be warm toned. This is great when photographing warm toned flowers. It is a problem when photographing cool toned flowers. When shooting cool toned flowers at this time, a white balance preset or manual white balance will need to be used in order to prevent a warm color cast in the image.
- Saturation: The saturation should be excellent.
- Direction: The light will cast gentle shadows that emphasis texture.
- Quality: The light is very hard.
- Color: The color of the light can vary from neutral to somewhat blue.
- Saturation: Very poor saturation.
- Direction: The direction varies from overhead to off to an angle. In any case, texture is minimized with this light.
White Balance
Photography is basically painting with light. The film or sensor is the canvas, the camera is the brush, and light is the paint. However, as covered above, the light that a photographer paints with often has a color to it. Film and sensor capture this color which then affects the quality and mood of the image.To create an image that accurately depicts what a photographer intended, the photographer must be aware of the color of light and must make adjustments when necessary. The subject of the color of light, and the techniques of dealing with it, are referred to as white balance.
To manage the color of light, photographers have three options:
- Auto white balance
- Preset white balance
- Custom/manual white balance
- The application does not require absolute maximum color accuracy
- There is not a preponderance of one color in the scene being photographed
- The photographer wants adjustments made for the color temperature of the light
With preset white balance, the color temperature is assigned by a photographer, prior to a shot being taken, by selecting one of the preset white balance options. Many cameras have multiple preset white balance options. For instance, a camera may have settings for bright sunny outdoors, cloudy outdoors, shady outdoors, tungsten, fluorescent, and flash. Preset white balance works well when:
- The application does not require absolute maximum color accuracy
- The light source matches one of the preset white balance options
One advantage of preset white balance is that it is not fooled
if there is a lot of one color in the scene. So, an orange poppy will
not cause problems with the white balance when the proper preset is
used. However, using a preset white balance is not the most accurate
method of handling white balance. This is because the light might not
perfectly match the preset. In other words, the light of a sunny day
might not perfectly match the color of the sunny outdoors preset on the
camera.
Rather than make assumptions about the color temperature of light (auto white balance) or fixing the color temperature at a given value (preset white balance), custom white balance actually uses the camera to measure the color of the light hitting the sensor. To measure the color of the light, a photographer must use a neutral gray or white object to establish the white balance. Typically, a photographer will photograph a gray card, or similar object, and use that to establish the white balance.
The advantage of the custom white balance is that it accurately records the color of objects as they would appear if the objects were photographed in neutral light. Furthermore, custom white balance sets the white balance much more accurately than either the auto white balance or the preset white balances. Therefore, custom white balance is the best option when:

- Maximum color accuracy is required
- The photographer wants the colors in the image to appear as they would under neutral light
Exposure
There are many ways to determine proper exposure. However, it is beyond the scope of this article to cover the various methods. On the other hand, it is worth mentioning that flowers can often fool a camera’s exposure meter. For instance, a white flower can fool the camera into thinking that there is more light than there really is -- resulting in an underexposed image. Thus, whatever method is used to determine the exposure, a test shot should be taken and the histogram on the camera screen checked to ensure that the exposure was really accurate.Wind
Wind is a perpetual problem for flower photography. Nevertheless, there are ways to minimize the wind’s affect.- The wind is generally calmer in the early morning. Thus, early morning shoots will tend to produce less wind problems than later in the day.
- The ISO can be increased or a wider aperture used in order to allow a faster shutter speed.
- An obstacle, such as a camera bag, can be placed such that it blocks the wind.
- The stem of the flower can be tied or gently fixed to something stationary.
- Simply wait for a break in the wind; then, take the shot. Repeat this procedure many times. One of the advantages of digital photography is that there is no cost for taking lots of images. If many images are taken, at least one of them is bound to be sharp.

Now that the technical aspects of flower photography have been mastered, it is time to delve into the artistic side.
Pristine with Character
Suppose that a chef wanted to create a great meal for a special guest. How successful would he be if he started out with poor ingredients? If his vegetables were not fresh and the bread was moldy, it would be pretty much impossible to create an enticing gourmet meal. For a great meal, it is imperative that the chef start with the proper components.It is no different with flower photography. In order to create great flower images, one must start with the proper components. In this case, the proper components are the flowers. However, not just any flower will do. The flowers must meet two criteria. The first criterion is that the flowers must be in pristine condition. This means that the flowers must be physically perfect. Flowers that are not perfectly fresh, have marks, or have been partially eaten by bugs should not be used.
Figure 1: Flower not in Pristine Condition
Figure 2: Close-up of Dried Up Portion of Flower
Having a pristine flower is a start, but it is not enough, by
itself, to guarantee a great flower image. Thus, the second criterion is
that the flower must have character. Now, character is a bit hard to
define. Perhaps, the best way to describe character is that it is
something that grabs one’s attention.
Figures 3 and 4 demonstrate this concept. Figure 3 shows a
flower. Now, the flower might be nice to look at, but it is kind of
ordinary. There is nothing about this flower that particularly grabs
one’s attention.
Figure 3: Flower with no Character
Figure 4: Flower with Character
Center of Interest
Figure 5: Center of Interest
This image also demonstrates a couple of important points about the COI. First, the COI is the object around which the rest of the image revolves. What this means is that the purpose of the rest of the image is to support and enhance the COI. This is clearly seen in Figure 5. The yellow color of the flower strongly contrasts with the green color of the insect which helps the insect to stand out. In addition, the center of the flower provides a simple pattern that contrasts with the lines of the insect which further makes the insect prominent in the image. Clearly, the rest of the image serves to bring attention to the insect and make if the most important part of the image.
The second point is that the viewer’s attention is constantly drawn back to the COI. As one views Figure 5, one will usually first notice the insect. After viewing the insect, the viewer’s eye will tend to examine the rest of the flower. However, the viewer’s eye will repeatedly return to the insect. This shows that the COI not only grabs the viewer’s attention, it also serves as a comfortable resting place for the viewer’s attention. This is a very important point because, without a strong COI, the viewer’s attention randomly roams around the image looking for something of interest; finding nothing, the viewer quickly looses interest in the image.
Figure 6: Subtle Center of Interest
At first, one might think that there is no COI in this image. However, after viewing the image for a little while, it becomes obvious that the viewer’s attention keeps coming back to the graceful curve of the pedal that works its way to the top of the image. Furthermore, the rest of the image supports this curve. The portion of the image directly behind the curved pedal provides a dark blue contrast to the light tone of the curved pedal. The bright yellow on the lower pedal serves as a leading line that leads the eye into the curved pedal. It becomes obvious that the curved pedal is the COI of this image. Consequently, while the COI of this image may be more subtle, the image still has a good COI.
Composition
Composition consists of how the objects in an image are arranged with respect to each other. Now, there are many components of composition. A comprehensive coverage of the components of composition is beyond the scope of this article series. However, two basic aspects of composition will be covered:- Rule of thirds
- Golden triangle
Figure 7: Rule of Thirds
Figure 8: Golden Triangle
Application of the rule of thirds or golden triangle helps make an image more dynamic and balanced. In fact, research has shown that people’s eyes tend to gravitate to the areas of an image located at the intersections of the dividing lines of the rule of thirds and golden triangle. In contrast, placing the COI at the dead center of the image can make the image have a very static feel. Placing the image at other locations can often make the image appear unbalanced.
That said, these rules are not absolutes. There are times when the rules should be broken. However, when the rules are broken, it should be because breaking the rules strengthens the image.
SGD
Each person has her own style when shooting flowers. I have developed a style that I call SGD: simple, graceful, and dynamic. These are essentially the goals for which I strive when setting up a flower shot. These goals are defined as follows:- Simple: To create a simple composition that directs the attention to the COI and eliminates all distracting detail that does not support the COI.
- Graceful: To use compositional elements that emphasize the grace or elegance of the flower.
- Dynamic: To use compositional elements that strongly attract and hold the attention of the viewer.
Simple
Simple Definition: To create a simple composition that directs the attention to the COI and eliminates all distracting detail that does not support the COI.The simple goal is addressed with five techniques:
- Subtraction
- Move in close
- Selective focus
- Blurred background
- Contrasting background
Similarly, when applied to flower photography, the art of subtraction involves removing everything that does not support the COI. Why is this so important? Any element of a flower image that does not support the COI will distract the viewer’s attention from the COI to weaker elements of the image or may even lead the viewer’s eye out of the image entirely. This results in a weak image and is obviously undesirable.
Figure 9: Distracting Detail
Figure 10: Simple
Move in Close: Moving in close helps
to make the COI larger and more dominant, and it also removes
unnecessary detail along the edges of the image.
Figure 11 shows this concept applied to a rose. The COI of this
image is the center of the rose. By moving in close, the center of the
rose is much bigger and more dominant than would have been the case if
the camera had been farther away. The only details that are left are
the curves of the petals that provide a shape contrast to the diagonal
lines of the center.
Figure 11: Moving in Close
Selective Focus: Selective focus uses a
very narrow depth of field such that the COI is in focus, but
everything else is out of focus. The result is that the viewer’s eye is
naturally directed to the COI.
Figure 12 shows the selective focus concept. A very narrow depth
of field was used so that everything but the tip of the leaf was left
out of focus. This removed any distracting detail and draws the viewer’s
attention directly to the tip of the leaf.
Figure 12: Selective Focus
Blurred Background: This technique is
similar to selective focus. The difference is that only the background
is blurred with this technique. Once the background is blurred, any
background detail is eliminated. Then, the COI naturally stands out.
Figure 13 shows an application of a blurred background. As can
be seen, the entire flower is in focus, but the background is not.

Contrasting Background: The
contrasting background technique minimizes the background detail and
strengthens the COI by utilizing a background that contrasts with the
flower. The contrast can be of tone, color, or pattern.

Graceful
Graceful Definition: To use compositional elements that emphasize the grace or elegance of the flower.The nature of flowers is one of grace and beauty. Much of this comes from the lines and curves of the flowers. So, the intent here is to use the lines and curves of the flowers to help communicate that grace to the viewer of an image.
The graceful goal is addressed with two techniques:
- Leading lines
- Curves
Figure 15: Leading Lines
These leading lines function as mentioned. They lead the viewer’s eye to the COI, and they also exhibit the graceful nature of this flower.
Curves: Curves sole function is to display the graceful nature of flowers. They do not point to the COI like leading lines.
Figure 16 illustrates the use of curves. There are several green
curves receding into the background. These curves display the elegant
shape of the leaves, but they do not lead to any specific point in the
image.

Dynamic
Dynamic Definition: To use compositional elements that strongly attract and hold the attention of the viewer.The dynamic goal is addressed with three techniques:
- Saturated colors
- Contrasting colors
- Contrasting lines
Figure 17: Saturated Colors
Of course, the question of how to capture saturated colors now becomes very important. There are two primary answers to this question. First, the right flower must be found. Second, the flower must be shot in the correct light.
This flower was shot during a break in a rainstorm. As covered in the section on light in Part I of this series, overcast skies enhance color saturation .Thus, the heavily overcast sky enhanced the colors of this flower and made the image possible. Had this flower been shot in bright sunlight, the image would not have been very successful.
Contrasting Colors: Our attention is
strongly drawn to color contrast. Furthermore, this is not just a
psychological phenomenon. It is actually build into our
sensory/perceptual systems. In other words, from a nervous system point
of view, we are hard wired to respond to color contrast. As
photographers, we can use this to our advantage by seeking out subjects
of high color contrast and photographing them in such a way as to
emphasize the color contrast.
Figure 18 depends on color contrast for much of its impact. When
setting up this shot, a search was performed to find a flower that
would allow the camera to be situated such that the background was the
solid, luminous green of the spring vegetation. This provided the
necessary color contrast that makes the flower stand out from its
background.
Had a different position been chosen such that the background of the image was the brown rock wall from which this flower grew, the image would have lost most of its impact.

Had a different position been chosen such that the background of the image was the brown rock wall from which this flower grew, the image would have lost most of its impact.
Contrasting Lines: Contrasting lines can also add a dynamic touch to a flower image.
Figure 19 illustrates the use of contrasting lines. Actually,
this image uses both contrasting colors and contrasting lines. This
serves to make the COI, the flower stalk, stand out from the
background.

Wrapping Up the SGD Approach
Now, in demonstrating this approach, one image was shown for each technique, and an explanation of how the technique improved the image was presented. However, when out in the field, multiple techniques can be used with a single shot.
Figure 20: Multiple Techniques
Simple: Subtraction was used with this image to eliminate all distracting detail. Moving in close and using a contrasting background were also used.
Graceful: The stem of the flower serves as a powerful leading line that leads to the COI. In addition, the petals serve as curves that display the graceful nature of the flower.
Dynamic: In addition to contrasting colors, saturated colors were used.
In short, this image used most of the techniques presented in this article. In general, the more techniques that are used with an image, the more likely that the image will be successful.
