My first on-topic blog post in a while
After recently acquiring quite a lot of aerial roll film of 9.5", 5", and 70mm widths, I wondered how to shoot the stuff in my 11x14".
You could of course make a modified back and holders etc, but a much simpler and less costly solution occurred to me: a simple paper sleeve. This is illustrated in the attached cellphone pictures. It works very well and costs almost nothing.
