The idea was to zoom parts of the photos to actual size, to get rid of ceiling and other areas, where nothing happens. However, when I zoom photo to actual size, it looks like this: Unsharp and somekind of "dotted". With noise.
I don't have much experience in still photography, and I don't know what is the name of that problem to google it. Can someone explain, what I am doing wrong, and how to fix that kind of problem in the future? Thank you in advance.
I am using Lumix G6 with standard lens.
