I was just lookng through some of my first commercial shots for some source images... (I've found that if I go back much later on I often go 'Oh, hey... that one is cool, why didn't I use that before?') Anyway, with a lot of shots I find myself finding all the errors I made... some of them aggregious... "Oh my god... f13?! What the hell was I thinking?!" "1/20th of a second without a tripod?! Well no durr it's a little blurry, dumbass!" "Ack! I can see myself in the reflection of that mirror!!!" etc.
