Regard this picture of my cat. It’s quite a nice ‘snap’. Moomin took a break from chasing a toy-fish-on-a-rod to pose. If you like cats it’s the sort of picture that will make you go awwww … if you don’t like cats you’re probably not that bothered either way. If, however, you’re the sort of dreary dullard that spends far too much time making sure all your pixels are sharp, your histogram perfectly balanced and your straight lines straight you’ll just be looking at how the focus hasn’t really worked, how there’s a burnt out bit at the back and how the crop has lost a bit of ear and a bit of paw.
Such people are to be pitied, ignored and – occasionally – be the brunt of short strawman arguments on blogs by people who almost certainly couldn’t get a horizon straight if you paid them.
