The less-tolerant development characteristics of T-Max are of little consequence: it isn't at all hard to get the required consistency. I never liked TMY much, but TMZ was useful. I much prefer D400, and slightly prefer D3200, respectively. D100 is great, and I'm not sure I've ever used TMX.(posted 8926 days ago)But I would emphasise prefer. I wouldn't claim that Delta is better, just that I prefer it. OK, so do many other people, but lots of people get on well with the yellow box films, and if it works for them, there's no reason to change.
