Pretty neat, right? It’s sort of like a variation panoramic stitching or combining images into a high dynamic range photo.įrom here, it’s all automated. 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. Stack Photos to Extend the Depth of Field I’d like to return to that subject this week, because I’ve now found a free program you can use to make photos with an “infinite” depth of field. A few years ago I explained how you could take a series of photos with slightly different focal points and combine them into a single image with very deep depth of field, with everything in focus.

That’s still in the lab, but you can use software to fiddle with the depth of field even now. A technique called computational photography, for example, promises to let you change the focus and the depth of field on your PC, so you can make someone in the background of a picture snap into focus. One day you’ll be able to change almost any aspect of a photo after it’s taken.
