I have just returned from a trip to Ecuador with my Linhof (what a load to lug a round, but hopefully worth it) and have a lot of slides (6X7) that I would like to process. I'll be using Ilfochrome to do the darkroom work and would like to know if there's any discernable difference up to 11X14 between the RC papers and the deluxe papers. I know the deluxe comes in 3 contrasts and the RC only medi um, but it is twice as expensive. I have also not worked with contrast masks, w hich from what I read seems difficult, and was thinking of using the RC for medi um contrast and deluxe for low. Any comments appreciated.
