printing problem: shadow at edge of projected imagegreenspun.com : LUSENET : Large format photography : One Thread
Hi All, and apologies if I'm repeating some often-answered query... just don't even know what to call the problem. Anyway, I recently got a beseler 4x5 dichroic color head for b/w printing. A band of light occurs along the edge of the image projected on the paper. It casts a shadow on the projected image and an adjacent band of light outside the projected image. To my very amateur eyes it seems like a reflection from the vertical edge of the negative carrier (at the edge of the negative). What is it, and what can I do?
If it seems like I'm a guy with a bunch of equipment who has no idea what he's doing... you're right. I live in a small town in the Middle East. It's just me, an inherited Crown Graphic, a Beseler enlarger and three Ansel Adams books. You are my only help!
Thanks, and Happy New Year!

Tom, You've correctly identified the problem (who says you don't know what you are doing!). There are several solutions: 1. Try applying some flat black paint to the edges of the negative carrier. A lot of times the black paint is rather shiny and reflects a lot of light. 2. File the edges of the negative carrier so that they are at approximately a 45-degree angle instead of vertical. 3. Leave a little "breathing room" at the edge of your negative when you compose and then crop in a bit when printing (I'm sure the full-frame purists are shuddering at the suggestion). Hope this helps, ;^D)
