The little irregularities in the last photo kept bothering me, so I decided to try and fix them with some digital trickery in the GIMP. While I was at it, I also enhanced the contrast slightly to brighten up the bottom a bit and make the pattern on the wall more prominent. Here’s the result:

You probably have to directly compare it to the previous version to actually notice the changes in the bottom right. And only if you pay very close attention you can see parts of the cheating in the final image. While I don’t normally do this kind of manipulation on my photos, it is very common among photographers and I find myself playing with it more often these days.
