wbis ? I tried something similar but I still was seeing christmas colors in the hair I wanted to get rid of, which is why I did a hue/sat and some selective median to the channels. But your method is also a lot faster.

Gaussian ? You're probably right. Most consumer level cameras are default to shoot in JPEG and often it's impossible to switch out of that mode, so since I've always gotten the files in jpeg format, I guess I've just been making a mental leap. I think I kind of knew that, but was getting caught up in the nominclature. Yeah, noise is going to be a problem with shooting in lower lights even with a traditional chemical film or a high end digital camera. Part of the reason you experience this in the blue channel is that blue light takes up about 1/3 the size of the spectrum as either red or green. So there is much less gradiational data available, hence, less light makes more drastic contrast shifts. I guess if I'd thought about it long enough I probably would have posted different. Like I said, the solution is basically the same... shoot with more fill lighting or deal with the noise in the channels.

I think a lot of people get in the mindset a lot of times (myself included), that you can "photoshop it later" and don't worry so much about taking a good shot. Something like that was a spur of the moment snapshot, but it's amazing how many posed portraits I see with the same issues. It's always better to fix your lighting and dof beforehand rather than try to play catchup later. Glad you were able to find something that works. Yes, for a consumer level camera, those sony's are pretty good quality. They do have issues with shadow data though. To alleviate some of that noise, try turning off the flash and using incandecent or halogen lighting if possible for fill... the flash tends to really overpower the photo on those camera. A flash is only good to about 12 feet anyway... so generally it's not that useful.

Party on
