I do keep pertinent information on the negative sleeve as far as exposure time, contrast filter and burning and dodging is concerned. I do not keep track of the development times because of the fact that there are too many variables in my darkroom ettiquet to make them truly consistant, meaning for example, I do not mix fresh developer for each session, so the strength is going to be different in any case, I don't have a rigid temperature control for the baths, again a variable introduced.
A magnetic stirrer would be quite handy when mixing the B part of PMK in any case, and those with an additional warming surface look really good...hmmmm....maybe...
The bar stool, (but without the bar I take it...)
I'm a "tray developing kind of guy". I've looked at Jobos, and even used Jobos as an assisitant many years ago, but for now, I have the luxury of having a large darkroom, with more than ample sink area, and I like the "quiet time" spent in the dark...
BTW, I just ordered a digital thermometer of the style you suggested Eugene.
Jim, what wattage bulb do you use in order to make your judgements "correct" as far as the tone and contrast of your prints are concerned? I still take a print out of the darkroom to check it by daylight. I think I do that so that my eyes become adjusted to the daylight and I seem to be able to make more accurate assesments in this manner. Sure, I wing it too with the lights in the darkroom, but if I'm matching an enlargement to an existing print, then I need the old daylight method.
