You then set the focus so that it is sharp at the location nearest to the camera that you want to be in focus, press the shutter, and the camera will take the sequence with no more work on your part. Even shooting at F/22, maximizing the depth of field for that lens, didn't allow me to make the entire central part of the flower to be sharp.įuji's X-T3 has a feature called focus bracketing, where you can set up the camera that manages many of the mechanics of doing the image shoots: you set up the distance you want between images and the number of images you want to shoot, and optionally, a delay between images into the camera. This was shot with my 60mm macro at F/11, and you can see clearly that only part of the image is sharp and the sharpness falls off severely away from the front part of the central part of the flower were I set the focus for this. It is the first in a sequence of images I took that I later stacked together. Here is an image I took the other night of a flower. If you ever see macro images of something like a flower with a deep depth of field, or a landscape of a large flower field where the entire field is sharp and crisp, there's a good chance those images were focus-stacked. It turned out, after having a chance to talk to him, was because he shoots a lot of stitched panoramas and focus-stacked images, so you can't take the kind of images he shoots with a single image out of a camera.Ī focus-stacked image is more or less the same thing as a stitched panorama, except that you're moving along the focus plane as opposed to the horizon. I first learned about focus stacking when I sat in on a lecture by George Lepp, a photographer I've long appreciated and whose images I found very difficult to emulate. Focus stacking is a way to create an image that is sharp across a wider area than the hardware camera/lens combination's depth of field would otherwise allow. ![]() One of the things I've been wanting to experiment with for a while is focus stacking.
