light leak : LUSENET : Large format photography : One Thread

Just got my colored contact print from the lab and noticed there were like bluish blobs and streaks coming from the lower edge extending to the middle part of the print. I had 4 shots taken of the same subject and the pattern is identical for all shot. Some were more noticable than the others because they were a bit overexposed. I never had this problem before with my black and white negatives, there were no light leaks present. Just wanted to find out if this could be a processing error by the lab. Can a leak cause a bluish blob? Thanks in advance

Any chance you can scan it and post it here? From what you describe, it could be a light leak. If it were a processing problem with the chemicals, I would think the same pattern on four different prints would be odd. There could be a light leak in the lab's equipment. I would think (hope) that someone in the lab looked at them and would recognize if they had a problem.

What format is this? Is there one negative printed on each paper sheet, or several negatives to a paper sheet (like 4 4x5's arrayed on an 8x10?)

I had the 4 4x5 negatives printed on one 8x10 paper. I never had any problems with light leak before in my B/W negatives. I checked my camera for leaks but just noticed a few pinholes at the bellows. Aside from that, I don't see any major leaks.
