A horizontal group of elements continuously sags. A vertical stack just sits
there (only moves down, anyway). The individual parts can be made lighter.
It is hard as hell to keep a (especially home-made!) horizontal enlarger
aligned. The drawback, of course, is head room. I can project to 30 x 40 in.
in a standard 8 ft. high room. The vertical enlarger can take up less
useable space too. Another advantage with stacking elements I think is that
you can more easily do unsharp masks and such.
I have friends with vertical, home-made 8 x 10's that use anti-newton ring
glass. In a dry, dusty climate this can be more of a problem. I use a
humidifier when it is too dry.
