Which free photo editing software would you recommend me to use? I'm doing a project and some of the pictures I have are a bit blurred (I know it's impossible to make them look completely defined, but at least I would like to make them look better).

GIMP has a function that can sharpen up images. It might have an un blur somewhere.

 

I'm not really an expert on photo editing software though.

I'm going to look now for that function.

It's called unsharpen mask or something like that.

I have no idea why it is called unsharpen when it actually sharpens.

 

lol Because nothing about computers and programs are logic.

Because it's free. That's why *nods*
