4x5 Peelapart Instant Film and other Large Format Photographic topics.
Yup. It doesn't really work for the 100B. IIRC, the dye is from solarization after peeling. Still, there isn't much usuable here. No matter the 3000B works so well and it is faster.
These were peeled in the dark. Maybe not dark enough? I need a real darkroom anyway.I am impressed with the 3000. Very handy stuff - who needs light anyway?
Nope. Pulling another in complete darkness got me the same thing. Why? Fuji shows this is just a silver neg and a receiver sheet in their data sheet, just like FP3000.
The answer to my previous question is this: The DTR process is SO efficient and acts like such an intensifier or amplifier, that only extremely small amounts of silver be present in the negative.Very small nanolayers of silver are well known to have the colors observed here.But there is also a second effect - some of the intensified "black" appears to go back onto the negative, producing what appears like a solarization effect. Perhaps it is not, but instead a consequence of DTR. It would save a lot of money to use almost no silver, and Fuji would be smart enough to do that.
very interesting, i got the same type of results when i did this with 100b immediately after reading your 100c negative recovery. I did not do it in the dark, but in the light, and had assumed it was solarization, if you look closely though, there are no Mackie lines, which you might expect if it was true solarization
James,I am told the colors are the photonic size of the silver particles, which are smaller than a micron, and the reversal that we see is a result of the DTR intensification process, which has a a gain of almost 1000, which is why you only need such a thin negative. With coarser grain as in the FP-3000B, we see a normal negative, presumable due to the macro size.This suggests that we could pull the negative of FP-100b immediately after spreading, then use an intensifier such as selenium to make a more usable monochrome negative. Not sure this is easier than just shooting and processing a sheet of ordinary film though.
