Agfa color print CP 1 treatment in reversed color process.
Camera Practica L, lens 50mm 1.8.
Exposure:
- Shooting - 1/60 1.8 + 3 Wratten 85 filters;
- fogging - 1/30 strictly red filter 190 lx.
It sees the left side of the image fogging shifted.
Lack of fogging = bluer.

I will like the pictures.
Sorry for the picture attached here.
I was and the subject and the darkroom boy who cleaned darkroom after.
Sharf is crazy.
No exposure conditions were not optimal.
The picture of the scale (link) is closer to reality.
Tests done by 2000.

Put here and the image with color scale.
In the left side of image you can see a portion that has not received fogging.
It is darker and cyan.

That looks really interesting! What process did you use to develop these, normal E6 or what?
Also, the CP1, is this the Agfa print stock used for motion picture films when they are projected?

In short, there is not E6, is a patented process of me.
On long, I wrote here in post # 18
(there was a url link here which no longer exists)

„Positive color films is made to make color prints after negative or internegative color.
Positive films (whether color or black and white) are made with a small fog and a
contrast factor about 4-5 times higher than the contrast of negative films.
Color positive films is used for print machines (contact or optical) being balanced for incandescent light (~ 3000 ° K).
Color positive films, Kodak, Fuji, Agfa, Azocolor (occurred in Romania) is developed in the
ECP 2. http://motion.kodak.com/KodakGCG/uploadedfiles/motion/h2409a%281%29.pdf
By year 1997 I made an invention - process reversible color of the positive color films.
http://www.osim.ro/publicatii/brevete/bopi_2005/bopi0805.pdf (page 115 - 116) LINK
I made many contacts copy tests have with color positive films Kodak 5386 and outside (photo).
I try to be as short as possible.
Let me give you some information about the photo tests:
- Outside sun (32,000 lx);
- Exposure / diaphragm 1/60 1.8 + 3 (three) filters Wratten 85;
- Fogging with strictly red filter - 1/30 at 210 lx without the photo objective at Opemus light;
- Praktica camera L - Pentacon 50mm 1.8 lens.
I make the reversible color processing in a process similar to E 6.
My processing have: a black and white developer, stop, second exposure, color developer....
After processing the film a color positive image directly resulting.
Color reversible process made by me, besides the fact that they get direct positive image, we have reduced the contrast of the color positive film.
The contrast images obtained is lower than that obtained if it were make in the recommended process ECP 2 (obtain a color negative image).
I have to search through CD s to find some scans images to see.”
