KODAK TRI-X 400 - Ei :125~1000
NORMAL dr5 ISO: 320
Tri-X in reality are '2' different films. 'TX' is a different film type than 'TXP'. Different in contrast, tonal range, and overall feel. TX comes in 35mm & 120-rolls.
TX [new emulsion] in developer 1-neutral has a 1st rate neutral. The slight haze of the old emulsion is gone. In developer 2-sepia, TX is slightly less toned than its cousin TXP i.e. the color is a lighter, sepia /yellow.
NOTE
ON OLD TX: Those
of you that have the old emulsion TX in stock please be aware that this
film is ageing rapidly. We have noted that both older TRI-X films are
becoming difficult to run in DEVELOPER-1 NEUTRAL. There is an increasing
yellow stain in these films. If you are using old TRI-X it is best you
run the film in DEV-2-SEPIA. As always we recommend you use fresh film.

While the image quality is fine, old Kodak film is best run in DEV-2. The older the film is the more the highlights will be lost. The films condition worsens with age. Cold store works in some cases but it is best to test this film for use in dr5.
NOTE: TX must be fresh when exposing past 400iso. It is important to keep this film away from any X-ray or heat as the higher iso will show the slightest damage. Damage from age, heat or x-ray can be seen as; lower dmax, lower contrast, blown out whites and a masked haze.
