I took several photos of a drawing that a friend had made, but the quality of the photos is not very good, so I need software that can produce enhanced images by combining a stack of images of the same scene that were taken during a short period of time.

    Another comment from my side: I think it would be best if you share some of the images, or at least describe what problems they have.

    • Is the resolution not high enough? --> Try Upscayl
    • Are they blurry? --> Good luck. Rescuing blurry pictures, either because of motion blur or lack of focus, is the hardest/ almost impossible thing in photography. You could try some “AI” tools, depending on how sharp the image is, but they usually suck.
    • Are they noisy? --> Maybe try Topaz Denoise (paid and proprietary) or GIMP/ Darktable (FOSS, but not exactly as sophisticated or quick). Sadly, canceling out noise usually results in a “watercolor” look if overdone.
    • Or do yo just want to recover information? -> Increase contrast, sharpness and middle tones.

    Either way, since you asked specifically in c/Linux (which I find a bit unfitting personally, better ask in c/Photography), I can recommend 3 Tools:

    • GIMP of course, maybe with plugins, for general editing, and Darktable for post-processing (color grading, sharpening, etc.) your images. The latter one works best with RAW images, which you probably don’t have since you shot on a phone.
    • Upscayl for Pixel interpolation (usually doesn’t increase sharpness, just the pixel count if yo want to crop more or print a poster at higher resolution).
    • And maybe Huggingface, which also offers quite some image processing AI stuff.

    But as I said, please provide some pictures, or at least more information. Just saying “muh pics bad” is almost worthless for me.
