Photo Forum / Film Photography / Darkroom / February 2006Enlarging 6x12 negatives
How are 6x12cm negatives enlarged with a Beseler 45 enlarger? Is there a glass-less 6x12 negative carrier or should one modify a 6x9 carrier? I know a 4x5" glass negative carrier can be used, but would prefer a glass-less solution. Robert > How are 6x12cm negatives enlarged with a Beseler 45 enlarger?

How about moding a 4x5 glassless then? Easier to add some guides to a 4x5 then to cut open a 6x9.

Material is much thinner than the material in a carrier and it was just basically a hacksaw job (tho' from the quality of the cuts I suspect it was a jeweler's saw or Dremel tool cutoff blade that did the deed). And at least one firm is making after-market carriers of quite good quality for about $60-70 dollars, these turn up on eBay for less at times. That's where I got my 645 for my Omega.

It's not like the Beseler carrier is that complicated.

You can even get a couple pieces of aluminum at a hardware store, drill corner holes, insert a metal cutting hack saw blade and cut the opening. Finish off the edges with a file, spray paint it flat black, and it is done. Francis A. Miniter > How are 6x12cm negatives enlarged with a Beseler 45 enlarger?

For "odd" sizes, I use a glass carrier with a thin black vinyl sheet cut as a mask and placed over the negative which adds spacing to prevent Newton's rings. Alternatively you can use thin flat (check it) Masonite finished on both sides (similar to a clipboard). Hold two sheets together with double sided tape, and cut the outside dimensions. With the sheets still attached, small drill holes at the corners of the film opening, a couple at the edge for alignment locator pins or four near the opening for negative alignment, and a couple for negative stage locator pins if someone should use an Omega D#. A Durst may require strips glued on the bottom. Separate the sheets, and using a jigsaw or saber saw tilted to 45 degrees, cut out the opening on each sheet to give a beveled edge. The ground stubs of a couple of flathead screws may be glued into one sheet to serve as locators for the boards, or if four are used, for the negative strip. After sanding down to 400 grit, paint flat black on the outside, and gloss black inside to prevent scratches on the negative. It only takes a few minutes to make the carrier if you have or can borrow a jigsaw, drill press, and adequate planning/measuring skills. Plexiglas and Formica scraps work well also.
