you'll find that you won't see people chopping other peoples pics all that often. it happens sometimes, but not often.

besides, it's pretty good. twitchy nailed the only thing i can think of.

sandyeggo325i · 08-12-2009, 12:29 AM

that's me chopping my own pic

but yea, thanks...

Actually the noise doesn't bother me, but the posterization in the sky is a little bit distracting. This happens when you crank up the contrast so much that the finite number of levels in the original image starts to show. Best way around that is to work with 16 bit images (if available in your original RAW conversion) or, if necessary, reduce the contrast a bit in the effected area.

Posterization is where you get discrete colors or levels instead of a continuous variation in tone/shade. It happens when you amp up the contrast too much. Suppose you start out with 256 levels (8 bit) and this shows up as a nice smooth variation on your monitor or print. Crank up the contrast enough and you'll only be working with a small fraction of that 256 and you'll start to see regions with distinct colors and sharp boundaries between these regions rather than the smooth transitions found in an unboosted image.

Or for the official version: http://en.wikipedia.org/wiki/Posterization

i kinda like the "before" better.
you tried to bring out too much blue that wasn't in the data and that's why you got the noise in the blues.

samandy121 · 08-12-2009, 02:21 PM

I too like the before one more.

sandyeggo325i · 08-12-2009, 09:00 PM

cool thanks guys...just screwing around trying to self learn myself this stuff...

rodi, do you have any tutorial type suggestions?
