I LOVE the 6x7 ratio and want to mark the Hass focusing screen for that ratio to crop at the time of composition. Any suggestions on exactly how to do that? I've had a hard time finding methods that seemed practical. Seems like there should be an easy solution, but have not found it. Any suggestions from you experts?
The 6x6 format is evolutionary baggage from the beginning of the TLR days when it was typically cropped to 6x4.5. Not that it can't be compositionally useful, but the 6x7 format is more flexible.
