The first picture is the original. The second one was corrected using the gamma correction, red .94, green 1.70, blue 1.70. The third one was the curve, but I don't know the settings. I keep on trying things, and then forget to mark down what I did.
This Christmas tree was under-exposed to get the effect of the lights, etc. I experimented with it to get other effects. The first one is the original, the second one is histogram adjustments: luminosity 1.56, high 190; green 1.00, 155; blue 1.00, 104 high; red 1.00, 247 high. The last one, I used the equalizer -- I think. It was an interesting experiment, anyway.
I was forced to take some pictures at a time of day that was not conducive to what I wanted. Is there any way I can brighten up the right hand corner, or have I lost all detail, regardless? I tried curves and brightness, but nothing lightened the right hand corner. The first picture is the original. The second one, I used the histogram functions, equalized first, then midtone compress, 21 red, 235 green, 17 blue. The last picture, I have marked in my notes: green channel, R 6, G 100, B 14. I was not satisfied with any of them, but thought you might have a comment on a solution -- outside of going back to Santa Fe and taking the picture over again.
I greatly appreciated all your work on this class, and am very glad I took it. Vikki had suggested that I do so.
