Unmask 4x5 color negative.

[WootSK]

Hi, I am wondering if there are any unmask 4x5 color negative that I can get in the market today? I am looking for some of it to do some experimental developing test.

Cross process E6?

Trying if it is possible to do reversal processing with C-41 chemical. (Something like the "RR-4" processing I did on RA-4 paper in the past) I did cross processing of 4x5 Ektar 100 before long ago. But to my knowledge, I never seen an unmask 4x5 color negative, so asking the guru here if they know of any so can test it out and also do another cross process to compare.

how about the recovered negative from Fuji FP100C? I bet that is unmasked.

An aside here, what is an "unmasked" negative ? I have stripped a fuji negative, it looks like a fairly dense negative to me.

An unmasked negative is a color negative without the orange dye mask. You get this result by cross processing E6 film in C41. There have been a few films made without the mask:

Yup, I saw those a long time. But I'm looking for 4*5 format instead of 120 format. Thanks for the reply.

When we talk about unmask, we're talking about color negative not instant. Thanks for the reply anyway.

I know, just using it to reply to the other question about what an unmasked negative is.
