I just got into the world of 4x5 as of today. I have a Toyo 45AX and a schneider 150mm f5.6 lens. I shoot mostly landscapes. I shot four shots of the flatirons here in boulder, co this morning with fuji velvia quickloads. Here is my questio n. There appears to be some sort of light leak on the negatives. I have what see ms like two lines(like ghosting) that run vertical up and down the negative and end about half way up. the are on the end of the quickload farthest from the met al strip at the bottom and nearest to the where the envelope stops when pulled o ut for exposure. The negatives that where shot closed down(f45) appear worse tha n the negatives shot open(f16). Any suggestions as to what may be causing this w ould be appreciated. I know the fuji quikloads have a great reputation therefore i am sure 99.9% that it is something i am doing. Thanks, Tom Mangan.
