I took this picture with my crappy cam and now I’m looking for a away to reduce some of the noise in this picture. I’m looking for an easy way, for a non-professional like me, to enhance this picture on Linux.

What you need to use is the GIMP filter “Selective Gaussian Blur”. Note that this comes with GIMP nowadays, and it is NOT the same as regular “Gaussian Blur”. For an old, but accurate, tutorial on this tool, check out the GIMP help page on it:

I tried it out on your picture, with a blur radius of 5 and a max delta of 10, and it fixed the noise almost perfectly, while keeping the image sharp.

Thank you, both options worked pretty well. I think I prefer greycstoration though. Good options, easy to use.
