Could I pick your collective brains.
I am disposing of an old Nova Fibre Based Print Dryer but have been

Hi..I am using a Metz 45 CT4...On my old Mamiya Super 23..with a 50 mm lens.
Using a 6x9 back..I believe the lens covers the equivilent of 21 mm in a
35....The flash with wide angle attachment covers i believe 28 mm...straight

I have a Canon AE-1 programmable. Some years ago I bought a Quantaray
40" cable release for long exposures. Though I rarely used it, it
worked fine until recently. But now, when I press down the plunger of
the cable release, I can't get the camera to fire.

I'm revealing is obvious.
The problem will be designing a single-line sensor fast enough to, say,
dump out the values of 3,072 pixels in one 2,048th of an 8 millisecond

What type of color correction filter do I need to remove the excessive blue
from white LED's.  White LED's are pure white to the eye, but my camera sees
blue also.
I built a ringlight for macro use with my Olympus C-770 digital camera,
