Why photograph insects? Because:
• 75% of living creatures on the planets fall into the insect category
• They can often be fascinating subjects with great natural beauty
• The “ugh” factor the insects inspire in most people prevents us from having a close up look at the real thing.
Photographing insects is a very specialized field and volumes have been written on it. However, there are three basics you need to know when you start and once you “whys” and “how to” of these, you will be ready to go deeper into special effects and also start experimenting on your own. Your camera handbook and articles on macro photography will tell you all you need to know about macro lenses and close up filters so we won’t go into all there here
- Sharpness of image is one of the most important facets of insect photography. We’ve all seen images of flies and other insects where the minute hairs on the body are visible. Without this effect, the whole impact of the image will be lost. The easiest way to ensure a sharp focus is to use the auto focus option on your camera. When doing macro photography, even the slightest of hand shake can change the depth of field and affect the sharpness of the image, so any shake after the auto focus is complete will affect the picture. Use the normal technique of half pressing the shutter button to start the auto focus and take the picture as soon as possible. To minimize handshake, use a minimum shutter speed of 1/125th of a second.
- Lighting is a common problem in insect photography. Of course you can use a flash, but the problem with using a flash when macro photographing against brightly colored plant backgrounds, which happens in most insect photography, is that the natural colors are sometimes lost. With a 1/125 shutter speed an insect that is not well lit may cause the auto focus to fail. In that case try manual focus and if that still does not look good, then go in for the flash option.
- Once you have your subject tin the proper focus, the next thing to do is look at the background. A blurred background will keep the attention on the insect. The easiest way to do this is to use the maximum possible zoom. A plus10 macro lens at 84 mm focal length and a plus 4 lens at 210 mm will result in the same magnification but latter option will produce a smooth blurred background effect. Another thing to remember is that the greater the distance between the subject and the background, the more blurred the background becomes.
- The final issue is framing. For the best effect, try to capture the insect from the front but at a slight angle. This will allow the head to be seen in relation to the body and keep the image in balance. With few exceptions photos of an insect’s back are not of any great value. Keeping the insect slightly off center in the photo will yield positive results. Try using the “rule of thirds” for this.
Once you’re producing good results with these three techniques, you can start looking at experimenting on your own.
