Hello:

I am sure this info has been posted before, but I wasn't in need of the
answer previously.

1) I picked up a used 8x10 Cambo bellows - no model number. It has what
looks like a 'flange' on the front (now lensboard) for a lensboard that
maybe 'snaps' or locks into position by sliding into a mount of some sort.
Is there a way around this to use homebrew lensboards? I don't want to start
unscrewing screws because they look more like they hold the bellows on than
this mount, but I guess it's probably more than one piece there.

2) I believe it's a thin leather type (?). Surprisingly flexible...it
collapsed into itself for shipping/storage. I was told it had some light
leaks. Nothing immediately visible to the naked eye. Suggestions for repair
material/substance?

3) The 'back end'...don't know what to call that end...where the filmholder
would go, is a flat plate with a lip. The shape is square and larger than 8
x 10. I suppose it's larger and square so the filmholder can be installed
with either orientation. I further suppose the 'filmholder board' is clipped
with some sort of clamping fastener into this because I see no mounting
holes for screws.

The larger process bellows hasn't arrived yet - it's 38# packed, so that
rules out a portable field camera without an assistant! (:O)

4) I had tossed out a few questions about enlarger lighting, and the
responses along with additional info gleaned from other listserv lists and
Google Groups suggest that since the lens illumination is clearly variable,
there is no point in measuring the
light out of a cold head itself - you have to measure what hits the easel.

Is unevenness a problem only in the corners or also at edges of coverage? I
had been thinking that a multi-lamp head could be adjusted to be brighter or
dimmer in a grid or matrix layout by measuring the lighting at the easel.

Is this logical, or impractical?

Thanks

Murray
