They tend to have a wider contrast range too. Other methods (DMap in Zerene Stacker and Method A/B in Helicon Focus) creates less noisy, better quality results. It also compensates better the Lens breathing effect (or the gaps occurred because of literally moving the camera in this case) compared to the other algorithms. Method C and PMax creates an extraordinary job on very thin parts like hair follicles. Although the picture is more contrast and it creates something like a halo effect especially on the highlights. By cleaner, I dont mean better, but most of the time the results from these methods are usable without any combination. PMax and Method C are relatively faster to calculate compared to the other algorithms. PMax’s algorithm is very similar to Method C (Pyramid) in Helicon. The logic is to collect all data and use the best parts of each. Methods A and B has Radius and Smooth settings, where Method C does not have any setting. These are Method A, Method B, and Method C. Helicon Focus offers 3 different focus stack methods, which you can retouch and combine them.
Lets see how they do when actually processing the images. Wow… I was expecting DNG to be faster but more than two times? I wasnt expecting that. Since file size of DNG is much less and make the format easier to load/reload it speeds up the whole pipeline, not only import/export.Įxporting timings for 66 images from Lightroom with the plug-ins: DNG file can hold the whole of your data with a optimum size and it can also hold the metadata. In fact, this format can hold more color data that a regular DSLR can shoot. With the 16 bit TIF pipeline there is actually no pixel data loss. So I stuck with 16 bit TIF export to test Zerene Stacker. Zerene Stacker does not have any raw support yet (which makes me surprised). Helicon Focus supports raw pipeline with DNG input and output. Pipelineįirst of all, Helicon Focus has a big advantage over Zerene Stacker in terms of pipeline. Although there were not any other processes during that time, the results are still should be considered as approximate. I used the same machine (i7/12GB Ram/SSD Hard Drive) for every step.

Today I did a quick test on one of my focus stacks to compare the capabilities of Zerene Stacker and Helicon Focus
