The atteunator would be useful for printing on standard graded bromide papers wouldn't it? Does the unit put out so much light that exposure times would be very short without the attenuator?
I assume this unit could not be used with variable-contrast papers in any way (no filter pack available)? If not, can the the upper unit of the ULF-28 be moved in any way so that we could use the vaccum frame and a VC light source from an enlarger?
Otherwise, how is the testing going? Anything new? Wehn do you anticipate on giving the thumbs up to AmerGraph and getting product reviews posted and published. I might suggest posting on www.mamutphoto.com also.
I have already placed an order for one of these and they will fill it pending the outcome of your evaluation.
Take care and thanks for your efforts.
