who'd have thunk it would turn out to be a processing tutorial
like that turtle.
my theory/motto/whatever in photography is to
get it right the first go. while raw images hold alot of data that can be drawn out, over altering an image can have dire effects, especially when veiwed full size (10mp or whtever rather than reduced for web) which will effect the way it is printed. if you get the exposure and focus right at the time you shoot you can really make something special out of it with a minimum of PPing, or still have a great print straight from the camera
of course astrophotography is all about extracting data from images
