Tri-X: TX vs 400TX. Difference?

[sockeyed]

Can anyone tell me the difference between Tri-X TX and Tri-X 400TX? I notice that they have different development times. Is one an older emulsion?

I just bought a 100' roll of Tri-X and it has "TX" on the edge of the negative after development.

TX is the older emulsion. I don't know what the difference is other than the development times.


edit: post #100. 🙂

There is a Tri-X 400 and Tri-X 400 TX and Tri-X 320. Kodak's website explains some of the differences (direct link below). (I edited this after I realized what you were asking).

I have read (photo.net & APUG) that the old emultion was better, so if you can grab the old Tri-X you are a lucky person, I've had the chance to use a pair of old TX film and got thicker negs (that is better for me).
They may tell it's the same with some minor production differences, but it feels they are making a cheaper film.

I personally like the new one better - finer grain (almost as fine as Neopan 400), but pretty much the same characteristics in every other aspect.

The weird thing is, I just bought this roll 100' roll of Tri-X for my bulk loader. The edge of the negative reads TX only, but I'm guessing that it might actually be the newer 400TX. I'm confused.

Does anyone have negs that read 400TX on the edge?

I need to confirm so that I can get my development times right...

My new Tri-X 400 films have 400TX printed along the edges of the negatives.

Perhaps the seller had kept your film in storage for some time before you bought it?

I've run into bulked rolls of film old with the TX marks.

I don't have my negs here, but I'm pretty sure they say 400TX, as well. Thinking way back I seem to remember that old Tri-X had the 5063 designation along the edge, but that was many years ago. The Kodak link I sent in an earlier post list the same times for processing Tri-X and 400TX in 10 different Kodak developers.

As always is a matter of personal taste.

This place has pretty high turnover, I'm sure. The packaging looked to be in the newer style, too (but I stupidly tossed it out).

How long ago did the switch from TX to 400TX take place?

I think that from a developing point of view, I'll treat it as the newer emulsion and see what happens.

I've seen first announces of the new one about a year ago. My packages of 400TX have that "50th anniversary" label on them.

But it might be a good idea to check with your seller which one is yours. My bet is that it is the old emulsion.

I developed a roll of the new stuff last week and I just looked at it it says 400tx on it.
I had a rolled develop not to long ago in a lab that I had pushed to 1600 and it turned out great not grainy at all. I think I am going to like it..

The new 400TX stuff is great. Finer grained than the old but preserving the tonal characteristics and response we've come to expect. The only annoyance is the thinner (I think) base because I get more edge-to-edge curl when it dries than I did before. 400TX and Rodinal love each other...

hehe
i have just found a dutch shop which still has delta3200 in 120-format on a more than reasonable price (3,46 per roll, if 10+ bought at once)...so i bought some🙂
And some tri-x too... for euro3,26/roll... pushing plans ahead...
And some FP4+ for slower stuff, and some fuji NPH (very nice tones in 6x6!)
I think this will do for the 'flex and the super ikonta for a while 😎
My housemate will have a good laugh when he'll look for his eggs in the fridge (the appearance of the first 5-packs was already strange for him)

The PDF that I have is slightly different than the one Ray linked to, maybe it is older? It shows the difference in packaging between old and new. Seems the new states 400TX in green lettering and the old states Tri-X 400 in black lettering om the box. For the new one refer to Kodak pub F-4017 and for the old refer to Kodak pub F9. I hope this helps and not adds to the confusion.
