Shooting flowers almost feels like cheating. They are so beautiful that if you get the shot basics (lighting, composition, exposure and focus) right, the photo is always great. When shooting smooth colors at narrow apertures, sensor dust becomes very noticeable. Clean your sensor before shooting - and/or clone out the spots during post processing.
AI Servo focus mode and IS were used for this handheld shot. Lighting is from one studio strobe in a large softbox.
