Kodak Tri-X 320 (320TXP) in XTOL

EI is the speed the film was rated at when shooting. Evidence says where each time comes from: the manufacturer’s own data, a named test, a compilation or several agreeing reports (community consensus), or one person’s report. Times marked “not yet verified” come from secondary sources and haven’t been checked against a manufacturer datasheet. Where sources give different times, every one is listed and marked “sources differ”.

Calculated from the 20°C (68°F) time using Ilford’s temperature compensation factors, not taken from a datasheet. Most B&W developers behave well between 18–24°C (64–75°F).

XTOL

Fine grain, high acutance, full film speed, normal contrast. Excellent shadow detail with wide latitude.

Kodak Tri-X 320 (320TXP)

Sheet-film sibling of Tri-X 400 on a thick ESTAR base, designed for controlled studio and low-flare lighting; roll-film versions ended in 2010 and only sheet sizes remain.

Notes on this pairing

• Sheet film, large tank, agitation at 1-minute intervals (F-4017 gives no small-tank time for sheets).
• Two-stop push, sheet film in a tray with continuous agitation (the only EI 1250 data in F-4017).
• Small tank, agitation every 30 s; J-109 data for 120/220 roll 320TXP (roll sizes since discontinued). F-4017 large-tank sheet time is 7:30 at 20 °C.
• Small tank, agitation every 30 s; J-109 data for 120/220 roll 320TXP (roll sizes since discontinued). F-4017 large-tank sheet time is 10:30 at 20 °C.
• Small tank, agitation every 30 s; J-109 data for 120/220 roll 320TXP (roll sizes since discontinued). Kodak gives the same time for EI 320 and 640.
• Two-stop push. Small tank, agitation every 30 s; J-109 data for 120/220 roll 320TXP (roll sizes since discontinued). F-4017 tray (continuous) time is 8:45 at 20 °C.
• Two-stop push. Small tank, agitation every 30 s; J-109 data for 120/220 roll 320TXP (roll sizes since discontinued). F-4017 tray (continuous) time is 12:00 at 20 °C.
