Very cool. Thanks Jim.

I have yet to take the rear element off of the 30 inch Artar. I shot some portraits with it today, a 9th grader with her 7 foot Burmese Python. Two paper negatives and two HP5 negatives. Both in 11x14. That camera is harder to use I think than the 8x20 or the 12x20. I wonder why I feel that way...maybe it's that it's racked out all the way to use the 30 inch lens.
