Re: [APML] Sagittarius-M8 to M17

I agree with you, Jerry. As a E200 shot, this seems to be to much orange. If you were shooting Provia, as Carlos Sonnenstein did, I would have believed more this tone. It has a superior color balance. Just see pics of the Flame and the Horsehead with both films. The same happens with M42. So, Gary, follow Jerry's advice and more red to them.

Go to the Curves process, and select the Hue channel. I recommend you to use a linear interpolation, becouse is easiest to control. Also you may try to play a bit with the saturation curves.

Agreed! You have a lot in there. Nice result.
