Paper negatives

[donkittle]

Thanks a lot, Barry and Neil - ya, I was pretty stoked about how it turned out

chassis - I scan the negative, invert the image but retain the original tones. No digital tinting for me - I just never seem to get it right that way (the tones always look garish)

John - I bring the image into Photoshop and duplicate the layer. I invert the bottom layer and set the blending mode of the top later to color (and leave that top later uninverted, not that that's a word).

Thanks, good info.

A couple of friends came over to play dressup so we could do a few portraits on a Deardorff 8x10 with a Kodak Ektar 12inch f4.5 lens. I shot these on Galaxy Hyperspeed paper which I rate at ISO 20. I wasn't getting enough light on my subject even with my Elinchrom strobe cranked to full power. I noticed the flash sync setting on the shutter has both an M and X and that I was on M. Perhaps taping it in the X position would help...

Just started playing with paper again. Got a new (old) lens and made a shutter. Here is a shot with my Korona View 8X10, 7 inch unnamed Petzval, handmade guillotine/gravity shutter @1/45 sec

Can you please provide details on your shutter construction, operation and repeatability

Sure. I made this shutter out of black foam-core initially as a prototype to test and also for the light weight.

The piece on the left is the body, the hole is the same on both sides and fits over the lens snugly. The pieces on the right are the shutters, Different sized/length hole for different speeds. I didnt use math to figure out the sizes, just cut a slit about 2 inches long and started from there. I tested the speed with my dlsr, cut a slit half the length, tested again, etc. I was looking for 1/125th and the smallest slit happened to be it. I hold the bottom part of the shutter over the hole, pull the dark slide, drop the shutter,(i have a stop on the bottom to keep the shutter from falling out.) replace the dark slide.

Here it is attached to the lens.
It does okay on repeatability, but ideally I would want to make one out of wood with a metal slit. Right now, because I dont have the lens mounted properly, weight is an issue.
This is by no means a precise or completely reliable shutter. I estimate exposures are +/- 2/3 stop, but since Im just playing around, its good enough for me.
1/125th is the fastest I can get with this construction. I estimate I could possibly get 1/500 if it were made of wood and metal.
Hope this helps!
