New Film Advice

[Matthew Hoag]

I currently shoot 4x5 TMax 100 EI at 83, developed in trays with D:76 1:1. I am pretty satisfied with my results on the whole but recently I feel that the tona l scale is too contrasty - the middle greys are not smooth (for back of better w ording). This could be my developing but I am considering trying a faster film, ISO 400, as my understanding is that the faster the film the less contrasty the y tend to be (also bigger grains). My biggest enlargements are 16x20. This leaves me with 4 (albeit more, but for my area and availability), options: TMax 400; Tri X; HP5 Plus & Delta 400. I am not a big fan of the speed and dev elopment testing procedures and I realize that I "should" shoot them all and fig ure out which one is for me. However, I am looking for some direction from thos e who might have had some experience with the above 4 films that I can draw upon without having to test each film for EI and development times.

Looking at the Characteristic Curves on these they all look fairly similar. Are any of the films better suited for certain situations? Delta and TMax are newe r and therefore might they have more limitations with regards to available devel opers or in other regards? Any nuances that anyone has noticed and can share wi th me would be most greatly appreciated.

I continue to benefit from reading the Q&A on this forum and enjoy it immensely. Thanks to all those in advance who contribute.

you might try switching to Tmax developer. John Sexton has developed a method of diluting the Tmax developer to get a negative that is comparable in range to developing in Pyro developer.

If you want to stick with TMax films, I liked TMax RS developer when I shot TMax 400.

But for other options, a quick & easy way without testing is to shoot Tri-X or HP5+ at 1/2 rated speed, and develop in divided D-76 or something similar. The divided developer compensates, making sure you don't top out at the high end of the curve, and 1/2 speed gets you shadow detail.

While not as clinical as shooting for Dmin & running developing tests, you can actually test film by using real subjects.

If you want to stick with non-pyro developers, you might also give Divided D-23 a try with T-Max 100 or 400. Joseph Lipka has an article on it at http://unblinkingeye.com/Articles/DD-23/dd-23.html.

Matthew: If the problem which bothers you is something you are noticing recently, make sure you are using fresh D-76. Some people report contrast picks up when it has aged for a while.

[David A. Goldfarb]

I'll concur with the last comment. I don't find I have contrast problems with TMX (8x10") in D-76 1:1, but it does pick up if it's not fresh.

Also, what is your agitation technique? I develop in trays and do one shuffle every 30 seconds. If you use tubes, that could push up the contrast as well.

I remember reading about T-Max films from an article by Sexton a while back that was reinforced by others that had previous experience with T-Max films. The conclusion was that T-Max films are very picky on the subject of agitation and temprature. As a result, Sexton found them a good match with the JOBO. I found the same inconsistencies with tray development and just about gave up on the film. However, after I had a chance to see how this film could perform consistently with a JOBO, I got a CPP2. One of the things I love about this film is its reciprocity characteristics. I second the recommendation for T Max RS developer.

Forget Delta 400 in 4X5; it's been discontinued.

I would begin by looking at your processing technique. YOu should be able to consistently control contrast by your processing. Moving upto a faster film doesn't really solve the problem. With TMAX, as others have already said, It is VERY sensitive to temp and agitation. If you are not getting smooth mid-tines with TMAX 100 then something is off. Consider lowering your temp until it matches your agitation tecnhique or just slow down on your agitation. Maybe try other developers.

...sorry about my very sloppy typing above. After I re-read my response, it annoyed the hell out of me.
