Like any development method, times may need to be adjusted from the starting point. However, I've found that with almost every B&W film I've tried in my Jobo, the 5-minute prewet just about exactly offsets the effect of the continuous agitiation. Or, to put it another way, if you use a 5-minute prewet, you can use the times published for small-tank, intermittent agitation and be very, very close. And if you need further evidence, look no further than John Sexton, a confirmed Jobo user. FWIW, I use the ATL-1000 which is the earlier version of the current ATL-1500. The differences are pretty minor and ATL-1000s can often be found used for around $1000. It needs a tempered water supply, but once reels and chemicals are loaded, you just push a button, walk away, and come back when it beeps. These models have six bottles, so you can do the 6-step E6 process if that suits you. Even the older ATL-1000 has programs built in for the E6 6 and 3-step processs, normal and 1 and 2 stop push, C-41 2 step and 3 step along with pushes, etc. The C-41 2-step using Tetenal chemicals is dirt-simple -- easier even than B&W. - -- Rolfe Tessem rolfe@ldp.com Lucky Duck Productions, Inc. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
