Many cameras have a close-up or macro mode (often termed the 'flower' setting). Use this mode if your subject is less than 2 feet from the camera.
Shoot at the highest resolution possible so you have more flexibility when cropping the shot. We require you upload an image that is at least 800 x 600 pixels.
Set your ISO to the lowest possible number (ideally 50-200 ISO). The ISO setting adjusts the camera's sensitivity to light. The higher this setting, the grainier the photo will be.
