Masked stretch, but that's just my 2 cents. Most people would never touch the white point, only the mid range, but everyone processes to what they think looks the best. Many times I love what I did only to have mentors suggest a different approach, but they're saying how they like it.
Back when I was doing OSC imaging, I frequently produced images I thought were great, but once I looked at them an hour later I realized that the color balance was way off. As they say, I had spent too much time in the monkey cage. I have since then been cheating by doing monochrome luminance and narrowband images.
Could you provide a link to a tutorial on masked stretching or should I just get Adam Block's processing DVD?
Finally, I am indepted to your clear post on how to process in CCDStack in this old thread. Without it, I would have given up on CCDStack within 30 minutes. I owe you at least one beer.
