![]() ![]() Zerene Stacker is also a very powerful tool, but it also cannot automatically solve the common issues around high contrast edges as demonstrated in this thread. However, the built-in HF functionality is very useful for fast retouching, because it can pull in any source image or earlier rendered result as source for retouching with little effort. It's described here.Īlternatively, one can make several renderings, one optimized for edges, one for surfaces, and use these to make a new stack, if needed in Photoshop. ![]() It also allows to adjust the brightness of the area that will be copied, because both may have different original exposure, and the brush has a live preview to allow and match the required exposure level of the copy before actually copying. It's easier to do than to explain, but the retouching functionality is very useful. The source and destination image are shown side by side, so one can choose which looks better, and only paint in the better source areas. In Helicon Focus, on the Retouching tab, one can select any of the original layers to use as source for retouching certain areas of the image, but there is also a button called 'Use another output as source' which allows an alternative earlier rendering (different method or with different parameters) to be the source for copying. ![]() The Pro/Premium versions have great retouching capability of the layer masks, but one can also export masked layers to Photoshop for further tweaking there. So while Method A is my first preference with method B following closely, I may mix it with edges from method B or C. 'Method C' is good at finding very complex edge and occlusion detail, but will alter contrast and tends to enhance the impression of glare. 'Method B' is very good at rendering textures on smooth surfaces, and can do a better job on sharp edge detail. because the left and right side of the lens entrance pupil have a slightly different perspective, like looking while alternating with one's left and right eye closed). However, it may occasionally have issues with occlusions and edges, leaving a somewhat halo like edge where the lens allowed to look a bit behind an edge (e.g. 'Method A' is very good at maintaining color, contrast, and surface detail. Using Ps, you'll want to use the "Load File into Stacks." script, again align if needed, and then run the Auto-Blend.Stack Images workflow.Helicon Focus offers several methods/algorithms to determine the best parts of a focus stack. Using Bridge, you'll want to use "Load Files to Photoshop Layers" or the "Stack-A-Matic" scripts, align if needed, and then run the Auto-Blend. My guess is these came from pioneers hacking the Photomerge feature before Ps had support for Focus Stacking. It's unfortunate that there are existing works that try to use the Photomerge workflow for Focus Stacking. ![]() It would also break compatibility with existing actions and scripts that expect things to be a particular way. To collapse that workflow into the HDR, Focus Stacking, or Statistics features would be counter productive for more users than it would help. It was originally devloped for making panoramic images. Photomerge in Photoshop (Ps) was implemented a version or more before HDR and other image stacking features were implemented. The first aligns and blends to make a larger image from semi-overlapping images, while the second aligns and blends to make a similar sized image from (ideally) wholly overlapping images. Short story is that Photomerge is a very different use case than Focus Stacking. Quite by chance, I have just received an e-mail asking for help on this issue and referencing the very image which I used to test the two procedures in this thread (which is admittedly rather an extreme case because the image in question is a seed inside a blueberry, shot through a microscope objective with a DOF of. I know that I had to work out a system for myself by trial and error. Even having Tool Tips in Bridge for these items might have helped.Īpart from anything else, how many of the independent books on Photoshop discuss the techniques of Focus Stacking, Stepping Motors, and advanced layer editing at all? Regardless of whether or not Photoshop is a "Pro application", there is no reason not to streamline procedures for greater efficiency and ease of use whenever possible and I believe that this is one such instance of where an improvement would be desirable. Well the current set-up was confusing enough for people to have used incorrect methods to write and publish Tutorials on the Internet and to have caused Tommy Guns difficulties in making Focus Stacking work. ![]()
