I am planning to build a 5x7 enlarger and would be grateful to anyone who has got one if they could let me have a few measurements. What I am after is the negative to lens board distance when making a 10" wide print, the negative to lens board distance when making a 24" wide print, and the negative to printing paper distance when making 10" and 24" wide prints. All this for a 210mm enlarging lens, which I assume would be the right focal length. (I don't have a lens yet)
Many thanks.
Alan
