It's a bit like a manual version of the 'variations' tool in Photoshop. Dmap can be a bit of a mystery so I have a heap of different preset settings set that I run as a batch job overnight and then use the best parts from each in the final image. Permutations are a bunch of Dmap combinations of all or some of the PMax slabs at different settings.Next: stack PMax substacks overnight on DMap.I usually have an overlap of about 50% between slabs, this seems to give me the separation that works for me. More detail means smaller slabs and longer processing time. Decide on the amount of images to blend in the slabs by looking at the trickiest areas and the amount of detail overall.I personally use ZereneVS but great things are said of the other two as well. Either use Slabberjockey, ZereneVS or MakeSubStackingScript ( Windows | Mac ) to generate the substacks in PMax mode. Slabbing: first generate PMax substacks.But if the detail isn't sufficient, then you'll want to improve the result by slabbing. Default Pmax gets excellent results and that's the best method to start with. Use ZereneVS, Slabberjockey, BugSlabber or MakeSubStackingScript ( Windows | Mac ) to generate your substacks. Slabbing is a time consuming and fiddly addition to the standard stack but there's no doubt that it makes your final stacks better. However, slabbing can do away with this problem because you're just stacking the slab of images that deals with the hairs, thereby avoiding the fuzzyness of the other things. When there are things both in front and behind a certain set of hairs on a stack then a whole stack on its own will show the out of focus effect of both those set of things. Shooting a stack is all well and good but a stack on its own is a rough instrument that doesn't always give the cleanest result for only a certain horizontal section.

Various methods can then be used to make the final outcome of the focus stack better during the following post processing stage. Focus stack processing is the act of taking your separate images and combining them into one unified whole final image.
