Yes, it certainly works. So far I've only tried developing very expired Kodachrome 25 and 40 using it, so I'd normally expect to see dark negatives - both films were shot at 10ASA and expired in 1985/6. Really I should have gone for 5ASA. I've also used some of the leaf extract to make a reversal first and second developer and tested this on 1981 expired K40 Super 8. The film came out looking quite pushed, I suspect that shooting at 5ASA will produce better blacks - the results were very similar to those obtained using my Caffenol reversal formula, hitting the emulsion with more light improved the density in that case. I neglected to weigh the bag of leaves and properly measure the water quantities, so I'll do that with the next batch and post the details and the results here. I plan to test Fruticonol with some Kodak SO-078, Tri-X (16mm), and also test it as a first developer with some Kodak 7240 (VNF-1). Rubus Fruticosus is one of a small number of plants whose leaves contain Hydroquinone, but I've not managed to find any references to how much the leaves contain. So far I've processed 100 feet of Super 8 K40 using one 800ml measure of extract, it seems quite effective (and its free).
