Zerene stacker vs. helicon focus9/6/2023 ![]() ![]() The images and the tif output are on the website. But, coupled with the halos it makes Affinity difficult to use to get the best possible output to use as input for additional processing. It does seem that the output from Affinity is duller and sometimes appears less sharp than the output of the other focus stacking software. The camera does minimal processing on the jpegs.Īs I asked originally - I don't see any settings, parameters or adjustments I can change for Affinity to optimize the quality of the output of the Focus Merge, but if there IS something, what SHOULD I be setting to optimize the output? I don't know if Affinity does this on every series 'cause I don't have the time to process them all through multiple programs and I need usable output from the image stack processing. I don't know why it would be relevant, but it was a Nikon D810, using a Tamron SP 90mm macro, on a very sturdy Gitzo 3540XLS. With enough additional processing I can get the Affinity output to look the way I want, it'll just take a little more clarity, sharpening, and HSL than it will using the other image. Which I presume is the difference in the two software program's default processing. "Image 'a' looks duller and more blurred than image 'f' which is clearer and brighter colour rendition."ĭuller, flatter. Which is why I asked the question in this forum. "I would assume that both images have been produced by processing the set of 4 images through Helicon focus and then repeating the same process through Affinity Photo's Focus Merge to make a comparison but which image belongs to which processing?" "It would also help if you could explain what you mean by "crop and resize." Are you talking about resampling the images or something else? "Ĭrop and resize means I took the full-sized output of the 7360x4912 px inputs and cropped it to show the relevant area, then resized it so it wouldn't be overly large when I stuck it in the forum entry. The files are 799.jpg, 800.jpg, 801.jpg, 802.jpg and affinity.tiff I have no idea whether or not you'll be able to download them, but they're on my website at I ran a new set, which may have been the same ones from the original post and placed them on my website. I was processing a bunch of series of images, and don't know which one I used for the original post. The only variable is which software did the processing. Yes, in some cases they can, but since they only appear in "a", I believe they're not the result of a problem with the input images. Could you post a link to the four original images? " " Certainy halos such as you show can be an artefact of focus merging, but I think we need more information. The halos in the image on the left do not appear in the image on the right. The images below them are close-up views of the images above. "a" and "f" are the outputs of those two processes. Is there some setting or set of settings I can/should be using to improve the output quality of the Focus Merge?Īs the original entry said, I ran a set of 4 images through Affinity Photo and Helicon focus. I'm using the Focus Merge (or image stacking) to create the raw material for further optimization in Lightroom and Photoshop, so I want the sharpest, cleanest output from the stack processing to start with.įrom my examination "a" isn't as sharp and has more "haloing" (or whatever you'd call that smear on the edges in the close-up images). ![]() The next images are a close-up of an area with "a" on the left and "f" on the right Image "a" is on the left and "f" on the right Only thing done was to crop and resize down to a reasonable size. No processing was done on any of the images before, or after, the image stack processing, so these are as close to un-messed-with as possible. These were taken outside on a "windless" morning, so there may be very small differences in position between shots. I took a simple, 4-shot series of full-sized jpegs, captured with a Nikon D810 using Helicon Remote so the intervals are consistent, and processed it through Helicon and Affinity Photo. To some extent because I'm hoping for a better tool than Helicon Focus for doing stack processing. I bought Affinity Photo when it went on sale. Current version (as of last Friday) of Affinity Photo.
