thanks for your suggestion, I will take some pictures of brick walls (guess that must be the best way to compare the images) and display them after the new year. I have a question though, since you can't really make a great comparison on the screen, how would you best make that comparison without downloading the huge files and making some 8X10 prints? I am wondering.
Yes the images have severe exposure challanges, the sky extremely bright the trees really dark.
Thanks again for the brick wall suggestion, I will try to post it after my vacation.
