I should caveat this review by saying the developer has far exceeded my negative processing ability. Something to work on, though I think I still prefer developing black and white...
Anyway, the instructions to make up the two solutions (developer; and combined stop bath, fixer, bleacher) were simple to follow, the latter mixture launching into an impressive exothermic reaction.
I've used these mixtures on ten rolls so far, in a Paterson tank, having never developed colour before. And I have to say I think it's pretty forgiving.
I don't have a water heater or anything to get the developer up to 39 degrees (compared to 20 or so for b&w!) so I tend to stick the container into a jug of just boiled water, and keep checking the temperature. Once it's ready, tip it into the tank, invert every 30 seconds, occasionally put the tank into a shallow tray of hot water so it doesn't lose too much heat; whack in the stop / fixer for 8 minutes, inverting four times every 30 seconds; and then I just use the tried and tested rinsing method of 5, 10, 20 inversions, with fresh water in between.
I've kept a note of the number of rolls, as the developer needs an additional 2% developing time above the base 3 and a half minutes for every previously developed roll. Allegedly it's good for around 24 rolls - I've read reviews that the drop off in performance when it hits is like going off a cliff, so when I get to 20 or so I might just use it for rolls I'm testing some cameras with... (or found rolls in cameras bought at auction).
But as I say, so far it's been very tolerant of my haphazard approach, developing Kodaks ColorPlus 200, Gold 200 and Pro Image 100, in 35mm and 120 formats.
At £41 I initially baulked at buying this, but if I get 24 rolls, that's less than £2 a roll developing cost, so we'll see what that cliff edge looks like, and probably get some more, then knowing when the limit is reached.
