    I have never used tmaxx developer before so a quick question. You take the liquid concentrate and mix one part with four parts water. 1:4 So then the Kodak tech sheet lists the times for Tmax 1:4 / tmax 1:7 / Tmax 1:9.. Is that Tmax 1:4 referring to mixing the concentrate with water at the 1:4 ratio or is that describing mixing the stock solution with water at a 1:4 ratio (thus a 1:16 concentrate to water ratio)? I usually think of the stock solution being 1:1 and dilutions being 1:2 or 1:4. But it sounds like the working solution of Tmax 1:4 simply refers to the concentrate and four parts water.

    You are correct. These dilutions are for the concentrate, straight out of the bottle.
