Hi Peter,
My recollection is that this is not exactly what you asked me via e-mail but I will take a crack at it.
Paul - A great pic and envious that HB's have already arrived. I see that the photo is oversaturated in the reds, but can i ask about the color cast?
You can ask Paul anything. Or me.
If you sample RGB values for white colors in the neck , find red is about equal to green with low blue vlaues. From Art Wolfe's book this suggests a yellow cast. If you try Filter Blur Average technique - get a yellow green grey color. So not sure how it's a red cast. Maybe this is just semantics?
You are talking about the whites in the neck. I was talking about the whole image, which is simply too red.
Artie how did you correct the color cast?
I used the Average Blur Color Trick. Details are available in the latest update of our Digital Basics File. Do you have Digital Basics? I spend dozens of hours here each week and have given away tons of stuff and all of my time pretty much for free. Much of the stuff that I have written aboout in the Forums has been excerpted from Digital Basics and other BAA publications (and I have noted such). As I do need to make a living there is some stuff that I need to save for customers only. In addition it is no fun re-typing long sections that you have already written.
Did you use level adjustment layers or the technique recommended by CHarles Glatzer at: http://www.birdphotographers.net/for...ead.php?t=7752
No. The technique that I use is much faster and much simpler. As screen capture shows, the RGB values are R=169. G=155. B=123. To me, that is a blue cast. To learn how to eliminate the cast and fine tune the color balancing, please see the Digital Basics File. It has tons of great info and tips and will be updated as long as I am alive and photographing. (I guess that that is somewhat oxymoronic....)
