When shooting macro photography for focus stacking, I use a tripod and a macro focusing rail to adjust the area of the shot that is in focus.įor the example used in this post, I shot eight images.
Focus stacking darktable software#
As to focus stacking directly, the only software package I use is Hugin. I prefer to work with open source software, but I am not against purchasing software when a good alternative doesn't exist in the OSS world. I do all my photography work in Linux (Gimp/Aftershot Pro/DarkTable/Hugin/QtPFSGui/etc). In this post we will talk about how I focus stack in Linux. In focus stacking, the user combines the in-focus regions of various images to render one image. It's a little related to HDR ( High Dynamic Range) in that in HDR one combines the dynamic ranges of many images into one HDR image. Maybe your lens looks best at f5.6 and you don't want to go all the way to f11.Īdd to this the fact that f11 takes a lot of light and you realize that shooting with a small aperture may not get the result you want.įocus stacking is the process of taking many pictures with different elements of the image in focus, and then combining the images so that the resultant image is in focus.
Some lenses may also not be at their best at f11. So if you are shooting something really thick and you want it all in focus f11 (or smaller) may not be enough. You still may not have enough depth of field. Just shoot at small apertures and stuff will be in focus. This means that shooting at f11 will have a much larger depth of field than shooting at f2.8. As the hole in the camera/lens gets smaller, the depth of field gets deeper. Let's look at both of these options a little closer. If you want to take photos that have lots of stuff in focus, you have two options: This means that the amount of stuff actually in focus in the picture is very thin. For instance, macro lens and macro methods tend to produce a very shallow depth of field. Macro photography also poses many challenges.
I don't know why, but it is one of my favorite types of photos to take and to edit. Taking images of tiny things is just freaking awesome. One of my favorite areas of photography is macro photography. Before we start, I would like to say thanks to both Tuxlink and Dockmakie for their comments, suggestions and help with this article.
