Great post, though as a Silver Halide addict I must point out one thing: In all photography that isn't still-life or model-based, timing is literally everything... if you miss the moment, you can't bring it back. If you think you have it but discover that once the negatives come back you horked the lighting, shutter, apeture, etc..., you cannot go back and re-create it. Even the best digital cameras only allow a very small extension of that window of opportunity with it's instant preview function. No matter what, once the moment is over, that's it. I find that even in landscape photography, the perfect moments are fleeting. Things like weather, other people inadvertantly walking into the frame, the shifting of light caused by the sun's own movement... these things require that if you get a perfect photographic moment, you seize it, period, and if you fuck it up, then too bad for you. As a purely technical example (well, a gruesome one to boot), consider the WTC attack on 9/11/01 - the photographers that best captured the moment wound up in the top print magazines. There's no way in Hell you'd ever want to even wish for a do-over session on that one... OTOH, I love Poser art (yes dammit, ART) because if I hose-up a render, I can go back and do it over, and over, and over... tweaking it until I get it just the way I want it. At roughly $300 to $500US an hour, you try getting a nude model to assume often unbalanced and difficult positions, then freeze while you tweak lighting, backdrops, etc... and if you're doing it outdoors? LOL! I've seen a buddy try and pull that off for a local advert - even in the woods, there's a damned crowd that eventually forms and distracts, and even the kindest model (clothed, duh...) tends to get real cranky after repeating the same positions over and over again. Patricia - I know from whence you speak - I gained one hell of a nasty scrape on my knee whilst racing up a real steep hill to catch the lake sunset photo I eventually used in one of my banner ads :) Oh no... CG art is MUCH much easier. :)
