A flower is probably on of the most amazing things Mother Nature has created. No wonder that flowers are probably one of the most frequently photographed subjects, especially by the beginning photographers attracted by their beauty and infinite patterns. There is a number of different styles and interpretations of picturing flowers. Young photographers are very much attracted to flowers since flowers usually don't move (unless it is windy outside) and don't mind being pictured. This makes them perfect "models" for beginners - picturing flowers is an excellent way to learn. You can easily experiment with lenses and filters, composition and exposure, and special photographic effects and techniques without worrying about the subject of photography itself.
There are numerous special effects that you can use in your photography. They include slide sandwiches and multiple exposures. You can also use wind to make your picture look "impressionist" or shoot through a textured surface, which also gives your pictures rather unusual look. There are also some special techniques you can use to give your images some original and unusual features. They include selective filter use, selective focus, and use of reflectors and diffusers.
So before you start to shoot, there are some general rules and concepts that you should consider while taking pictures of flowers. First of all, isolation is probably one of the most important things. Make subject of your photo as clear as possible. If you are picturing a group of flowers, try to isolate one or several of them. To get a good image you need to choose a specific subject out of the group to picture. Simplicity is also very important. There should be no hot spots, black holes, and extraneous elements in the frame of your photograph. Busy background is one of the things that should be avoided by all means. In fact, nothing can kill a picture faster than a busy background. So obviously, the background is at least as vital for a good image as the subject. You may need to reposition your camera by just an inch or less to go from a distracting background to a pleasing, muted, detail-less background.
Here's another thing to remember; this one is about placement of the Subject of your photograph. There are three "centers" in a frame: center-top, center-bottom, and center-center, otherwise known as "bulls-eye". It may seem illogical, but the first two positions are usually acceptable and the third one is usually not. Even though there are exceptions to this rule, the center-center positioning is best avoided.
