Photos are sharp after importing them into AP, and remains so for a few adjustments, then they start degrading with further adjustments. By the time I've made a dozen or so, the image looks terrible. I've tried sharpening and not sharpening before making adjustments, to no avail. Sharpening at the end does not bring the image back to its original look. I've used AP for a year now, and never had this problem until a couple of months ago. I thought maybe it started when I upgraded to version 1.9, so I went back to 1.8.5; the problem exists there as well. As per some suggestions in the forums, I've tried doing my editing at 100%, but I don't see any improvement; plus the image is 3 times larger than my monitor which drives me nuts! (imported images have always come in around 30%, and I've processed them with no problems before this issue started). I shoot Canon RAW & JPG, and I'm scanning thousands of negatives. The sharpness problem affects all of them. I'm hoping you can help me; I sure don't want to go back to Adobe PhotoShop after they screwed me out of PS6 after paying $650 for it... but that's another story...
