Set your camera on the “A” mode for aperture value and chose an ISO of 400-800 (or even higher) for more depth of field.1. Choose a medium telephoto macro lens (about 90-180mm for full frame cameras or 60-90mm for small sensor cameras). A comfortable working distance (distance between the front-end of the lens to the subject) gives you the necessary room for lighting and other gadgets that you may need for extreme close-up photography.
2. Get yourself a sturdy tripod to eliminate possible camera shake during long exposures which is common in close-up photography. High magnification also increases the effect of camera shake.
3. Carefully choose your camera position. Do not cast your own or the camera's shadow on the subjects. Look for the most pleasing lines and shadow pattern falling on the subject.
4. Switch to manual focus. Autofocus often does not work well in extreme close-ups that are half life- to full life-size shots. Focus on the middle area of the subject and stop down the lens aperture as much as the light allows (try to reach F/16 or F/22 if possible). This will give you the most depth-of-field possible (zone from front to back that is in sharp focus). If your camera is on a tripod, the long shutter speeds are fine, so long as the wind doesn’t blow, moving the subject.
5. Bracket your exposure in half-stop increments under and over exposed. Take at least two under steps and two over steps.
