For some time now, I’ve been intent on making a preliminary attempt at focus stacking. It’s not critical to my work, but I often think I should add as many tools as I can to my photographic toolbox. I’m already pretty good with High Dynamic Range (HDR), which is a form of exposure stacking, so focus stacking seemed like the next move.
Stacking is a way to blend more than one image. Focus stacking is blending several images, each of which is focused at a different point. The idea is to use sharp portions of each image to create a new image with more in focus. This can be useful for landscapes that have compositional elements at locations both very close to the camera, and very far from the camera, but it is an exceptional tool when it comes to macro photography of very, very small objects, in which focus ranges are so close that depth-of-field is razor thin.
The basic process is to import images of different focus areas into Photoshop, then tell Photoshop to blend them. You can put it into search engine to find a step-by-step, which is what I did. It wasn’t at all difficult.
For this attempt, I made one image for every rifle cartridge in the image, moving focus from one to the next.
This is my first try, and it’s incredibly rough. Obviously I need to read more about how to finesse this technique, and I need to practice. There are many more applications available in addition to Photoshop, but I have Photoshop as part of my Adobe Creative Suite, so it seemed like a good place to start.
Stay tuned for more focus stacking efforts!
