I want to focus-stack 10 images of 20MPi each. I do not have a photoshop license and am looking for some light-weighted tool which does not need installation (don't have rights to install). Ideally, there are many online tools out there for different image manipulations (such as resize image online etc...). Is there any online focus stacking service? I tried to google one but there were none. Do you guys know about one?

  • I know you specifically said you don't rights to install software, but please clarify: do you have another computing device that you do have rights to install software on? Perhaps a mobile phone or tablet? The point of my question is to distinguish answers along the lines of, "you're pretty much out of luck", from ones such as "not in the way you're asking, but if you're able to install a mobile/tablet app, you could try..." – scottbb Feb 19 at 23:20

    Look for a so called "portable" version of the tool of your choice. – rackandboneman Feb 20 at 5:46
  • Thanks folks. It is a company pc, which has super tight access rights, browser on it and microscope is connected to it. – TechCrap Feb 20 at 12:50
  • If you have access to internet, why don't you just use google drive or whatever to pass the photos to a computer with photoshop? – moot Feb 20 at 14:35

    If this is a work thing it would be quite reasonable to ask your IT group to install something suitable. You shouldn't be floundering around trying to find some way to bypass your work restrictions . – Peter M Feb 20 at 20:53

Maybe it helps someone, I have used following site couple of times to focus stack images: https://focusstackingonline.com/.

I actually tried it also on mobile and it worked.

I haven't used it, but you might look into Picolay. It has a "portable" install capability (i.e., no admin rights needed; run from anywhere)

  • Thank you for your answer. I tried searching for either a web app or a portable app for image stacking, and couldn't find it. Nice pull. =) – scottbb Feb 20 at 20:47
