Any of y'all ever tried it? The idea is to take several photographs, each having a narrow depth of field, and stack them to the point that the final image is entirely in focus with the "blurry" areas cut out. As most of you well know, taking "macro" type shots of a small subject with high magnification inevitably results in photographs with a very narrow depth of field. This can be countered to an extent by stopping down the aperture, but too much of that results in fuzzy images due to diffraction. With this method, you can capture the images at the preferable aperture for your lens, and still have the entire subject in focus. Pretty cool. Similar in concept to HDR processing. I read about it yesterday and decided to dick around with it for a couple of hours last night, and this is what I came up with:  Not the best in the world, I know, but more of a "proof of concept" type experiment to myself. Still needs some work, but it came out okay for a first attempt. Setup was a Nikon D3100 with cheapo 18-55mm kit lens at f/9 (I think) and a set of Kenko extension tubes. This picture was 22 images stitched together with CombineZP, and no other post processing yet. This little spider is about as big around as the top of a pencil eraser. For scale, if you look closely beneath him, you can see the grain of the sheet of printer paper he is standing on. And yes, he is still very much alive. The hard part is taking all of the pictures to stack quick enough to get the entire set before he moves even the slightest bit. Good times. What sayeth ye, Arfcom photogs? |
