If you use TMX at the specified EI of 100 and the required development time to get the film to respond at EI:100, you are actually 'pushing' the film by 2/3 stop (its true EI is 64.) The additional development to get '100' will over develop the highlights. Why are you using TMX? Delta 100 has an honest EI:100, and with PMK (14M @68), has excellent highlights. If you liked +X, try FP4+, a much better film with a real EI of 80. PMK for 13M @68.(posted 8400 days ago)
