3 ways to improve close-up photos
Take time to search for perfect specimens
Working close up means that any imperfections and blemishes are exaggerated, and will spoil an otherwise good shot. Take the time to look for the best examples of your subject and check them carefully in the viewfinder before taking the shot.
Keep things steady
Use a tripod to keep the camera steady and reduce the risk of blurring from camera shake. A tripod will also help you to compose the shot carefully, and allow you to look around the frame for distractions. It is also invaluable for precise focusing.
Optimise the lighting
Successful macro shots rely on recording fine detail, which is determined by the lighting. Overcast light is ideal, but also consider backlighting and soft early or late light. Control bright direct light with a diffuser, or cast a shadow over your subject.
