I had forgotten the simple joys of experimenting with cameras. Some of you will recall the old trick of reversing your lens to obtain macro photos. Here I simply took my 18-55 kit lens, reversed it, set it to 18mm and took a photo of my laptop monitor. I aimed it at a white part of the screen and you can see the three sub pixels per real pixel which combine together to give the illusion of white.
gattach was a handy tool to use for webmail clients like gmail. I couldn't find it anymore, but then from this discussion I found out that gattach is now affixa.
