>>2576778>>2576780It looks like shit (low contrast, grainy), because there's a yellow filter made my silver.
The magenta layer on the film (green sensitive) is also partly sensitive to blue light.
So, during processing, when you re-expose the film to blue light to help later form the yellow layer, part of the light would also expose the magenta layer and would cause colour contamination.
So, they built a yellow filter made by CL silver (acronym for Carey Lea), to block the blue light from reaching the magenta layer.
That filter is almost opaque, but it doesn't matter because in the end all the silver is fixed out, leaving just the colour dyes.
Unless you develop it in B&W, where of course you can't fix the silver out, because the silver actually forms the image.
So, you're left with the equivalent of a dark grey mask over your film, resulting in low contrast and increasing the global density, exaggerating graininess etc. .
The only viable solution to that problem is a special bleach used in B&W reversal kits, like dichromate bleaches (fucking nasty, toxic and carcinogenic), or permanganate bleaches (not so nasty, have to me mixed fresh).
However, these bleaches change the characteristics of films (contrast, DMax, ISO), so yeah, it's not a strict recipe with guaranteed results.
If you can get those bleaches to begin with, the market for them is tiny and I'm pretty sure there are restrictions (in EU at least) for the dichromate ones.
