Lines leading into the picture help create an illusion of depth to direct the viewer's attention to the main subject of the photograph. Look for, and emphasize them whenever you take a photograph. Lines and paths into photos can be actual or implied. The eye follows either one with equal ease. Paths and visual stepping stones can lead the eye into the composition.
Good composition is essential to interesting photographs.
Add Some Sparkle Aluminum foil is always part of my basic camera gear. It can be a wonderful reflector adding just a little more light to the shadow side of a flower. Keep the same basic exposure but use the foil for a bit of sparkle to the darker areas. As an example, look closely at the photograph here of a cactus bud. The photograph was taken in semi-overcast conditions with light coming from both directions.
