I've been poking around some online photo supply stores and I see that a couple of them have house brands. How do they measure up? And I don't mean the house brands that are, at least, named similar to the name brands - ex. Arista76 vs Kodak's D-76 or Kenmere's KMAX vs. Kodak's TMAX developers - which appear to be just the same formulations as the named brand. Also, speaking of Arista, is there any difference between the "Premium" and the regular versions? I ask this because I'm looking for some sort of reference point. Something analogous to the digital cameras that show the focal length of the lens and in parentheses 35mm equivalent - Xmm.
