I just started developing my 4x5s in trays. When making contact prints or having them scanned 2 show this odd darker area throughout the middle. I can't really see it on the negative so I am not sure how it's so obvious in the scan. Is it uneven development or something else? New to 4x5. Scanner is 4990. Camera is a Crown Graphic Special with 105 or 135 lens. It's pretty easy to get rid of in CS5 but if I am doing something wrong I'd like to correct it!

The first one shows it. That was the first scan with the scanner. I was able to correct it a bit by adjusting some of the settings for the 2nd scan. But I still needed to work on it in CS5 (just corrected this one quick). I don't think the third shows it but maybe it's just not as apparent?





Any help is appreciated.
