First, thanks for the exif info input. It does work in PSE 6.0, which I
use.
I shoot simultaneous RAW/jpeg, and I open the jpeg images as a group in PSE
6, and click on them one by one, making notes of the file numbers that show
promise. With your help, I can now get the exif data from those that I
choose to process. I then open the keepers in ACR, do RAW processing and
pass them to the PSE editor.
I now understand Chuck's comment that he would like to see a magnified
image of the right side of the histogram. I can see how control of that end
of the histogram can prevent highlight clipping. What does one do to reduce
the vertical peaks from being clipped? I have not figured this out yet.
Perhaps it is not all that important.
