Re: 2-bath

Keith, you're mistaken on several counts. First, not all 2-bath developer work the same way; some allow for contrast conrol, others do not. Second, there is no "inevitable" compression in midtones with all 2-bath developers. Perhaps your experience with 2-bath developers is limited to a few similar...

Re: mythology

The idea that 2-bath development is inherently better or worse than single bath development is pure mythology. Either approach is capable of the same results, and each has strenghths and weaknesses. If one doesn't know how to use either approach, results are sure to disappoint. Jay As you already k...

Re: Anyone tried the new 'Promicrol'?

Years ago (about 45 ! ) I worked at May & Baker's,Dagenham, and could get FREE Promicrol film developer powder. Then it was discontinued as the factory supplying the 'HEAP Sulphate'stopped supplying as it was carcenogenic evidently. Some years ago Champion Photochemistry (as M & B became) started s...

It sounds to me like the film is not being developed. The only thing I can think of is that you are experiencing some kind of "sudden death syndrome" of the product, similar to what has happened to some Xtol users. Some people using Xtol found that it would lose all activity all of a sudden for no ...

I strongly suspect that the developer concentrate is no longer active, throw it away and buy a fresh supply of developer, making sure you carefully check the developers expiry date. They go off quite quickly once opened and the concetrate is left in partly filled bottles. Tetenal Protectan gas can h...

Re: Neopan 1600 ---> 3200 w/ Microdol-X

Hey guys. I'm new to the forums, yeah whatever yatta yatta ya. Okay, here's my deal. I've got a couple of rolls of Neopan 1600 that I shot at 3200 with the intention of pushing. Now, I've never actually pushed film before (not on purpose, anyway), but I know how to do it. I've got myself a litre of...

I think all the developers suggested here are a good choice. Another choice that is quite popular in the UK where I live is Paterson Acutol which formulated to help enhance image definition. Ilford Perceptol which is similar to Microdol-X is now readily available once again. :)

D-76 & ID11 have been tried and trusted over many decades and are hard to beat. I actually prefer the results of T-Max films developed in D-76 than when they`re processed in T-MAX developers. (Unless the films are P-3200TMZ or Delta 3200.)

Re: Thank you...

Hi, Thanks for your advice, will try that. We are a small lab so I have no way of knowing about the film exposure. The tank is a 2 litre tank that take's 4 spools of 35mm at a time if that sheds any light on things. Thanks Again Lesley Hello Lesley, Just a suggestion, HC110 at it`s optimal allround...

Ilford PQ Universal is not recommended for developing general use B&W films, it is a B&W print developer although it can be used with certain graphic-arts films.
