A good way to make your subject stand out is to create an even background with no distracting colours or patterns. This can be done in a few different ways. Perhaps the simplest way is to use the physics of the lens you have to blur the background behind your subject. Telephoto lenses and macro lens when focused close can achieve this. Alternatively, you can create a white or black background to add some contrast and drama to your image. This can be done by over-exposing or under-exposing your background, or by using a prop in the background (such as a white sheet of paper or a black object).
