Set your camera to manual focus and tweak the focus until the rear of the scene is in sharp focus. As you can see here, I chose to use a pocket watch on a stand, but you can choose a flower, coins, or anything that makes an interesting subject. Set your camera on a tripod and aim it at something you want to photograph. They don't need to be macro photos, but since macros have such infamously narrow depth of field, it's the best way to experiment with focus stacking. Ready to get started? You'll need some photos to combine in CombineZM.

COMBINEZP VS COMBINEZM HOW TO
The last time we talked about this, I told you how to use Helicon Focus, which costs $30. Pretty neat, right? It's sort of like a variation panoramic stitching or combining images into a high dynamic range photo. Then you use a program to "stack" the photos and combine them so all the in-focus bits were merged into one photo that was sharp from front to back. This time, though, you set the camera on a tripod and take a series of three or four photos, each with a slightly different focal point, so a different part of the picture is sharp in each shot. You know that depth of field is very narrow in macro photos, so ordinarily you'd have to choose which part of the photo will be in focus, as you see in the picture on the left.
Imagine you want to take a close-up photo. In this case, the technique has become known as focus stacking.
Whenever enough people start experimenting with a new photo technique, it invariably gets its own name.
