Things You'll Need
Instructions
Attach the macro lens to your camera.
Select your camera settings. Use the "Macro" setting on your camera, if available. For manual cameras, it is important to recognize that macro photography requires extra light; a wide aperture or slow shutter speed is necessary to take a clear, well-exposed image. If the raindrops are moving, a slow shutter speed will cause motion blur, so using a wide aperture partnered with a high film speed or flash will be ideal.
Adjust the lighting. Direct light on a raindrop can cause overexposed areas. Use a reflector or white card or bounce your flash off of a nearby surface to diffuse the light being used. This will help create a more even image and avoid "hot" spots and overexposed areas.
Focus on your subject and take the photo. When using a macro lens and a wide aperture, be aware that the depth of field--the area of the subject which will be in focus--is very narrow, sometimes less than an inch. Double check your focus before completing the shot.
