Yes, I know, they're gimmicky, visually jarring, and all that. Still, I have some 35mm exposures from my Holga where there sprocket holes and rebate are also exposed. And I'd like to print some of these (in color). Could it be as simple as placing the 35mm frame into a 120 holder? I think I'd want to mask off the top and/or bottom edges, but how? Black construction paper and tape, or is there a more clever way, perhaps? Also -- not sure how to phrase this -- but will the light bleeding through the open holes cause any exposure problems? I'm using glassless carriers in an Omega C760 enlarger. Thanks.
