I recently stumbled upon a pack of Kodak Ektachrome Radiance III. Process is R-3 (or compatible). I'm unfamiliar with the process and have found little information on it other than that it appears to be a dye-coupling reversal process. I was wondering if anyone might know if there are any alternative ways to process this stuff, either in Ilfochrome chemicals, as a black and white reversal print (some documentation mentioned that the black and white, and dye steps were separate in development...sounds almost like kodachrome), or any other chemicals. Thanks.
