Great still-life subjects can be easily photographed with window light. Shoot the flower as a whole, and then crop in tight on interesting features of the flower. Pick out colour, shape, texture and detail. Use a small aperture of f/16 to keep the entire flower in focus, but also try some pictures at a wide aperture of f/4 and just focus on a small part of the flower head, a technique known as selective focusing. The great advantage of shooting flowers in your set-up indoors, is that your pictures won't suffer from a breeze moving the flower during the exposure, something that can so easily spoil a shot taken outside in the garden.
