Tmax Developer was originally designed for pushing Tmax 400 and later for Tmax 3200. I don't think Tmax 3200 looks good in any other developer; Tmax Developer is perfect for it. I also preer Tmax Developer over all others for Ilford's Delta 3200 film. It is a good general purpose developer for most films if you want a liquid developer. I've used it for Tri-X when I was too lazy to dissolve powder for D-76.
