Thanks for the advice about the size for submissions. Coincidently, after Russ' first comment I attached an image in another post at 800 on the longest size. I will try 1200 next time.
Doug, The file was full DR right out of the camera, with the trees being at the black end and little tone correction was done. Until your torn page comment, I thought the image looked OK. Now, I'll have to re-consider. Combining your comment with others I have rec'd over the last while, it appears I have a subconscious attachment to high contrast. A few years of therapy and I should be fine.
