Xtol and Delta 400

1:1 or stock? Which is the best?

Xtol and Delta 400 is a good combo. If both 1+1 and stock are developed to the same contrast then depending on size of print and maybe the type of scene you might be hard pressed to distinguish one from the other in my opinion.

I use XTOL for many films. However I've had trouble with Delta 400 and Delta 3200, along with Pan F Plus (unless diluted more, e.g 1+1.5). Some films don't seem to be very responsive to development times in XTOL so I suspect I may have needed to develop the Delta 400 film for longer.

I found Delta 3200 @ ISO 3200 very thin. I have to test longer times with replenished XTOL and pyro.

I use PyroCat-HD for 95% of what I shoot. I tried XTOL years ago when it first came out and it seemed interesting but then I started hearing about failures with XTOL. Figured I'd try and give it a whirl again. I just haven't been happy with my 35mm negs in PyroCat-HD. With the exception of FP4. I'm not all that worried about grain so unless the collective comes up with something really convincing I think I will try 1:1 on my first go around.

Delta 3200 at the recommended times for Xtol also gives me thin negatives. I’ve gone even beyond the EI6400 times. 15:00 at 70F in replenished Xtol works for me. You still lose the deepest shadows, but it brings up the rest of the densities to where they print well.

If I am shooting at 3200 then I am using a long lens on a tripod really reaching for the photograph. At that point I can afford to loose the deepest shadows. Do you have a development time for Delta 3200 at ISO 3200 in replenished XTOL?

This is probably a good starting point: https://www.photrio.com/forum/resou...lenished-xtol-for-17-30-at-24c-in-a-jobo.426/

I have 15:00 at 70F for EI3200(for a stainless tank), although if I’m interpreting the data correctly I probably need to add some time.

I haven’t done any film speed tests, but I arrived on that time by evaluating contact sheets and making prints. The negatives are always a little thinner than I find for other films, but they do print well.

When I regularly used Xtol, it was almost always at 1+1, for that extra sharpness. TMY, HP5, Delta 100 and 400 were lovely in it. If I ever use it again, it'll probably be replenished.

Thx Andrew

below the chart, I list densities for EI 1600 at 20:00 and 24C. If you use that time/temp, you’ll have a zone 5 of ~.70 and a zone 1 of ~0.02 if you shoot it at EI 3200. Zone 5 would be a smidge low and zone 1 would be pretty thin at 20 minutes for 3200, so more time would be helpful. This is of course in a jobo, so constant agitation. Delta 3200 is fairly insensitive to replenished xtol.

Thank you! I book marked these.
