6x7 on Omega B22 Enlarger

Well, I am aware that the B22 is intended for a maximum 6x6 negative.

However, I have been enlarging 6x7 Negs using a Beseler carrier. It is too big by what must be just a couple of millimeters in diameter. Because of this it sits with one portion of the circle elevated in the round slot (whatever that might be called).

I have adjusted the head such that I get vignetting only on one corner of the paper. Clearly not optimal but not really looking to go through the hassle of selling it and buying another right now.

Anyone else printing 6x7 on the 22B? How?

Same method I've used to print 6x9 with an originally 6x6 carrier in my Omega D: hacksaw and file.

Modify a correctly fitting 6x6 carrier -- you'll still be able to print 6x6 with it, just a couple strips of tape if you need to reduce the glare past the negative. Whether you'll get illumination in all the corners is another question, but if nothing else, your focus will be better/easier than with that "almost fits" Beseler carrier.

Just remember to buff those sawed edges when you’re done, right!?

Pretty straightforward now that you mention it. I was already looking for someone to write code to reprogram the enlarger. Possibly the wrong approach.

That's what the file is for.

If you have an enlarger with a CPU, RAM, and storage, I'm pretty sure you're doing it wrong.
