Velvia 50 – color reversal film expired for 18 years.

I did my tests with the reversible color process, compatible with E6.
Fresh films I did not have, so I used an Velvia 50, expired since 2001-3.
You can see the results here.
The images were corrected as close as possible to the image on the film.
I think that it does not look very bad for a film expired for almost two decades?
In the first image, the left frame is exposed to ISO 50 and the right frame to ISO 25.
So I have a loss of one stop in my reversible process.

Fuji pro slide films keep pretty well long after the expiry date in my experience.

I bought some Velvia 50 expired 2006. I was expecting skin tones to be redder but to me looked good. Perhaps the red calms down with the passage of time?

The photos were taken with a Pentacon Six camera with the Carl Zeiss Jena Flektogon 50mm f / 4 lens.
I scanned it with an Epson V800 with a 9 x 12 cm mask to cover the black edges.
The film stood only on one edge in the frame, the other edge was free in the air.
Exposure I made to ISO 50 (1/125 with f 11) and ISO 25 (1/125 with f 8).
The process is reversible color designed for me to process E6 films.
I have written about this process.
If you say that “Fuji pro slide films keep pretty well long after the expiry date”.
I'm curious to see how see an 10-year expired film looks with a classic E6 process.

By modifying the composition of the solutions I can modify the color of the chromatic of reversible color images obtained through my process.
See examples:
Excuse the scans that have edges to the image with reflections.
Because the edges are not pressed.

I made a new test with Velvia 50 expired since 2001-3.
I did my process E6 and a silver removal process from black and white development and the elimination of bleaching after the color developer.
That's how it came out to me.
I think I'll try to make some partial bleaching at the silver in the image.
It looks better here.

I was given some Velvia of similar vintage. I was not going to use it but seeing this I might try a roll or two to develop after the 3 rolls of Ektachrome I bought.

In order to see what is happening in the color image that still has an silver image I have done a test – Proba 445.
Silver-444 with silver image I sank about half in a diluted bleach solution.
I washed, fix, washed and stabiliser.
The photogram did not feel well in the spiral so that it could have sky with silver and partially shiny sky.
I put the photogram in the spiral with the lying image and somehow moved.

In this way, you can see both the color image with an silver image and a partial bleaching image on the same photo

I used in all tests Velvia 50, expired since 2001-3.
I want to recall you that sample (Proba 445) is a partial bleching of Proba 444.
The silver image was removed only partially - not altogether.
You can choose the degree of bleaching desired by each - to taste.
Silver can be gradually removed from the color image.
After fixation, silver can not be placed in the image.
In sample (Proba 445 2) there is an underexposed frame that by partial bleaching looks like this.
May by give you other ideas?
An E6 normal process (George) - image Proba 444 Velvia 50 E6 normal la 800.
I mention that all the images I corrected to look as close as possible to the film image.

In order to have a more accurate idea of what is achieved by silver retention in the color image I have another comparative
example normal color image with color image with all silver and color image with partial bleaching.
It's a reversible color image that I've underexposed when I shooting.
The right side is processed in my normal color reversible process (with bleaching).
On the left side is the same exposure that has been processed to remain silver in the color image.
The left half of this photo has been treated with a bleach - diluted solution, fix ...
Of course, it's recommended that the image be lighter for the remove the bleach in E6 process.
Over the color image will overlap and an silver image.
To me, in this case, it is inversely, that is, the image is darker.
For a better comparison, I scanned as a single image the E6 processed frame normal and the processed E6 process with silver retention.
I had to correct only the normal E6 image for color.
Underexposure of the reversible color film will result in a darker image than normal.
The silver that is formed during the color development phase will also be larger (proportional to the amount of dye formed).
The silver retention image will be darker than the normal E6 process.
Initial subexposure will create an atmosphere of evening, and by remove the bleaching phase gives another image dramaturgy

I made a test on Provia 400, expired from 2001-9.
I'm having trouble with the Pentacon Six camera which has begun two times to make me worry about exposure times.
Exposure 1/125 stops working, the curtain stays open until I rearm.
So, from sample 445, at Velvia 50 I went to work with 1/500 and 1/1000.
At Provia 400 sure 1/500 out is a current exposure.
I also made several frames with Lubitel 2, to prepare for possible changes.

I made a test with Provia 400 with Lubitel 2 camera (Proba 447 Provia 400).
For the last test on Provia 400 has given the pink tint - magenta I walked in the process.
Besides, I still had a problem that I did not have enough black & white developer and kept the film in the wash for about 45 minutes.
The film came out with lower black levels, but the colors are better.
Specially, I scanned the photo with Simona Halep and a 447 test photogram.
