C-41 and ECP-2D with only a developer switch?

Andrew,

please share your results afterwards. I have been thinking about this workflow as well; would be very interesting to see how those slides turn out!

Hah! My Howl is with Ginsburg... My bell should be left to my girlfriend.

But it's a negative, so you can't shoot with it right? You have to copy your neg ONTO it and then it's a positive?

Either way it doesn't have an orange mask right? So you could X-process this in E-6 potentially? And not have the orange mask?

I've shot both camera negatives and slides with it.

The slides looked pretty reasonable at the time, but I need to get my hands on the can again (2000ft can) I cant remember where I left it. Mine was Vision Print not Premier. Mine also has remjet to deal with.


For the slides, I think I recall using E-6 first developer at 30 degrees and diluted 1:1.

So because it has a clear base you were able to shoot it and x-process in E6?

 

[Photo Engineer]

Geez guys, you are lucky you got anything. The E6 family of films are Br/I emulsions in the range of 1 - 5 microns whereas the ECP emulsions are 0.2 micron Cl/Br grains. The developers are designed accordingly. The E6 process can over develop the ECP family of products if you are not careful.

Did they used to put RemJet on print film? The current stuff seems to not have it:

Yes, I gotta find where I put that strip, and also the can of film so I can do it again. I got better results as a camera film then I did contacting printing 5201 50D to it and running SD-50 (mixed from raw components, and yes I did use CD-2). I dont know why, must be my exposure. I couldn't quite get it right to look decent.

It's designed for projectable positive images. It's very close to clear, it has a slight bias iirc.

It's also designed for printing from negatives with the orange integral mask, through tungsten light.

Developer is on page 9-20

It's why I chose to dilute the developer, to lower the solvent action that would be faster, as well as the developing agents to reduce development rate, as well as process at a lower than normal temp (by 8 degrees C). I would have adjusted from there, but it seemed like a good starting point.

The other reason I chose to dilute, is also again to lower the solvent action, as I read somewhere in E-6 first developer formulations, that less thiocyanate results in increased yellow in the slide.

It's always fun to experiment and see what I you can use something for before you miss the chance to ever try.

Dan, your graph is lacing in the blue layer. Something is wrong with it.

It's Kodak's chart for the film

My apologies. The yellow is almost invisible in both graphs, but it is there. That appears to be the typical spectrogram of a print film or color paper in which the blue is the fast layer and the red is the "speed" layer or slowest. This is why you generally start with a 50R filter pack.

I normally shoot Ektar 100 in 120, but I do love projecting my 35mm slides.

So I was thinking, when I want to make slides, maybe I can just put my 6x9 negatives in some sort of carrier for my Nikon N90s, and strike the slides I want from the negatives onto 35mm Vision Premier Color Print Film. Along the way I realized how cheap the C-41 chemicals are, and thought that I might be able to run both processes (C-41 and ECP-2D) using the same bleach, fixer, and if necessary for both, "final rinse". I would be mixing my own ECP developer from the Kodak recipe right before I use it: I know it's not too shelf-stable.

Sounds to me like a great setup, at least in theory. I would be able to develop my negatives, look them over, and strike slides from them in the same day (ATL-2 makes it easy).

My question is, can I use the C-41 bleach, fix, and final rinse for ECP-2D?
Also, should there be a stop bath after development in one process, both, or neither?
And if anyone has experience exposing Vision Premier Color Print Film, your exposure settings please. Thanks!

I have just done some contact print onto print film. I have the ecp 2 developer and it is ok to use the same ecn2 bleach and fix. One thing to note is that there is a first and second fix in the process. I did the contact prints under an enlarger. It's a long exposure , at least 7 seconds. The main problem is that the colours are way off due to a lack of filters. 2000ft of print film is probably what is needed before you get a good print. Maybe I could use the colour head enlarger to filter the light, not sure that would work though.
