Somebody else mentioned it, but I'll echo the words again. Start off with one film and one developer. IMO, suggesting that someone use one film is not too much different than telling them to use only one leg. Eventually they'll get really good at hopping but in the meantime they're going to miss a lot. Regards, John S.

I am settling on Ilford PanF/FP4/HP5 as a set of films that will cover all my needs. I'm hoping these aren't going to disappear, or radically increase in price any time soon. From reading on this NG and other sources it would seem that using Ilford's own chemicals probably isn't sensible based on price and performance. But what to choose ? The Ilford chemistries are not cheap, but they do have liquid versions of most chemistries. Mixing up a batch from liquids and using it one shot sryle, isn't cheap, but it isn't raking chances with your negatives either, and offers good and consistant results. Home brew developers are often cheaper, but then you need all of the equipment, and to play chemist every time you want to soup a roll, you also need to be very careful mixing the ingredients, or you will lose consistancy. When I operated my fume room, from 1978 to 1983 I wanted consistant results on negatives, but I would fool around on prints, it worked, until I closed the fume room, because I moved, and didn't have room anymore. Personally, based on your shooting style, pick A film, then pick A developer, and stick with those, you will learn what that film is capable of, and what that combination will let you get away with, often it's quite a bit.

Given Ilford's current states of affairs, I wouldn't count on either. In fact I see that their prices here in America have risen a good deal since my last purchase. Of course Galerie is still worth it. From reading on this NG and other sources it would seem that using Ilford's own chemicals probably isn't sensible based on price and performance. But what to choose ? Ilford's developers are fine to use. Microphen is a good speed-enhancing developer comparable to T-Max RS. ID-11 is virtually identical as D-76. If you have to buy, at first, these are fine. Heck even Scarpitti's recommendation of Paterson developers will work. Pay the tarriff or home brew. That said, I still recommend purchasing your own chemicals and mixing your developers from published formulas. Yep I am tempted to try Prescysol from http://www.monochromephotography.com/developer.htm but I haven't found any independent reference to it - does anyone have experience of using it? Since it's a UK item I doubt any in the US have tried it and I haven't heard about it until this post. Sounds like a PMK/Windisch variant. WINDISCH CATECHOL DEVELOPER SOLUTION A Distilled Water (195°F) 750ml Sodium sulfite 80.0g Catechol 12.5g Water to make 1.0Ll SOLUTION B Distilled water 750ml Sodium Metaborate 100.0g Water to make 1.0Ll PMK DEVELOPER SOLUTION A Distilled Water (195°F) 750ml Metol 10.0g Sodium Bisulfite 20.0g Pyrogallol 100.0g EDTA (optional) 5.0g Water to make 1.0L SOLUTION B Distilled water 1400ml Sodium Metaborate 600.0g water to make 2.0L I suspect it's abit more complex than the above formulae. Still it would seem to be something with Pyrocatechin, given the Brown stain and the selective hardening of the highlights. From what I read (in my relative ignorance), a two bath developer approach seems very attractive. Do you mean two-bath or split stock ? The developer you reference is a split stock not a two bath formula. A split-stock combines the ingredients from a stock solution which is usually diluted (1:5:100 for this variant) whereas a split stock has the ^^^^^^^^ I think you meant "two bath" here. developing agent in the "A" bath and the alkali in the "B" bath. Divided D-76 Solution A Metol 2g Sodium Sulfite 100g Hydroquinone 5g Pot. bromide 1g Water to make 1.0L Solution B Borax 50g Water to make 1.0L Even this formula is not a true divided developer as there will be some development in the A bath, Most of the problems with what people call divided development occur with procedures using such a formula. When Kodak was researching using divided development for motion pictures, they added a load of Pure Cane Sugar to the A bath to prevent ANY development from ocurring prior to the B bath. Contrast was controlled in their procedure by changing the alkalinity of the B bath and varying the time of immersion. It worked, but it took a lot of effort on the part of the lab. Effort costs money, so, back to the tried and true and cheap; single bath development. But why then aren't they more popular? Two-bath formulas have a nasty habit of compressing the tonal scale. True, but that's what some folks want. Some of the two bath formulae I used were quite adaptable in varying the results. Diafine was tweakable by changing the B bath to one with Metaborate or even TSP ( Tri Poly Phosphate) to get contrast control and different curve effects. The same could be done with a variant of D-76, where the A bath has been acidified with Bisulfite, to stop early development of the highlights. In this case, adding more developing agent to the A bath can also affect highlights and density. But that's for later, when the OP has a bit more experience using the conventional approach. Are equally good or better results achievable in a single bath developer, if so what would be a good choice? I am now recommending D-76H for general usage with medium and large format films and D-23 for 35mm. If you're buying over-the-counter formulas then I would suggest Microphen and Perceptol. Good advice for starting out. I might add that using D-23 might be the best solution as there would be a big cost saving and it is a very forgiving developer. Look on the web for teaspoon equivalent formulations, and save on a scale, if you don't already have one. Regards, John S.
