I'm a very pushy guy. I need to indulge my old photojournalist habits or I'll feel stifled by my current fine art pretensions. ;>

A couple of favorites are TMY up to EI 1600 in Microphen stock solution and Tri-X at EI 1200-1250 (depends on the camera/meter) in Diafine. Very different flavors.

TMY, as described, delivers a contemporary look with punchy midtones, controlled highlights and decent shadow detail. It's a favorite of mine for theatre photography.

TX in Diafine is old school. It's the easiest way I know of to get the look of decades past. Very good, smooth midtone gradation, very well controlled highlights, odd shadow and lower tones. There's an abrupt transition from Zone III to IV that sometimes makes for peculiar looking photos.

Both print very well on multigrade RC or fiber paper. I've done some limited printing of my TX-in-Diafine negs on graded paper with good results.

Beyond EI 1600 I see better results from Tri-X in Microphen. Oh, I can get usable results from TMY but it seems to poop out quickly approaching EI 3200-6400.

Delta 3200 at EI 1600 in Diafine looks quite normal, real shadow detail and normal tonality. It is a bit grainy and somewhat low in contrast but those are normal for Delta 3200. I'm planning to try harder pushes with this film in Microphen.

Never tried TMZ that I can recall. I've had little success pushing HP5+, which is otherwise a terrific film at or near its nominal speed.

When we want just a little more speed for daylight use of slower films I've had good results pushing FP4+ and APX 100 up to EI 250 in Diafine, a good developer for traditional type emulsions.

Tho' some photographers report satisfactory results with T-Max films in Diafine I've been unable to duplicate their success. I prefer Microphen for newer style films.

In fact, between Microphen and Diafine I'd be hard pressed to choose one. Diafine is by far the most convenient developer, being indifferent to time and temperature regardless of film used. But Microphen delivers somewhat better results. Still, Tri-X in Diafine is something unique and special.
