I think the haloing primarily comes from the fact that I had to use a giant lamp blasting down on it (or my flash, which gave even worse results) in an otherwise quite dark room. As I said, I am really not happy with the lighting, but I think it suffice to show my keyboard and unusual layout. It was never intended to be a work of art. Besides, this is already a tad off-topic.
I actually go over my lens quite often, as it’s a small thing that’s nice to fiddle with in an idle moment. Granted, I don’t go over it with anything more than a t-shirt or fold of paper, so it could still be the problem.
I rarely take photos more than for practicality though. The train of thought around a photo like this is:
- Does it show what it should:
-Yes - good, then I use it.
-No - change something to try and make it better, then repeat question 1.
