FOCUS POINT
It is very important, namely to set the focus point when starting macro photography with a small subject. You can dramatically change the appearance of the image by selecting the right focus point. For example, you can shoot two images with the same maximum aperture opening, but the focus is changed to a distance of several millimeters to produce a very different effect.
AVOID SHOCK ON THE CAMERA
No matter how well your hand holds the camera when shooting macro photos, camera shake still often interferes with your photos. You also have to always use a tripod in macro photography. If you have one, you must use the remote to press the shutter button properly, so that the blur effect on your subject is not excessive.
