Delta 100

[pentaxuser]

i get gorgeous grain free smooth tones and sharp edges with delta 100 at ei 80 in perceptol 1:3 at 24 degrees.

Leon. I exposed D100 at ei80 yesterday and am about to dev. What dev time and agitation pattern at 24 degrees?

Thanks

try about 13 minutes with 1 minute constant then 8 inversions every minute thereafter - it all depends on your equipment and enlarger light source etc etc etc. that should get you somehwere near where you want to be

ilford Delta 100 is very low grain size film. Film to use with the best lenses in 35 mm, like Leica and Zeiss. To utilize such lenses one have to use and high accutance developer, as e.g. Rodinal is.

When work with rodinal, on density-exposure curve, toe in the shade parts is long, but still with good slope and three full tones (or A.Adams Zones if you like), when developed for condenser enlarger and grade 2 paper.

Recomendations:
1. Expose as iso100 if you do not know real film speed (determined by a special tests).
2. develop in Rodinal 1:50 for 7min and 45 sec. After that spill quickly developer out.
3. while developing: flip for 30 sec in the first minute, and for 10 sec each next minute.
4. developer 20 deg.C plus/minus 0.4 deg
5. after developer is out rinse with water arond 20-24 degC for 20 sec.
6. water out and poor the fixer in for 5 min (ne w fixer)
7. dry and your film is ready for paper 2 grade to make prints as you saw the object. You got the best out of your lenses.

If it came in 5x7 I would shoot no other film. Love the stuff.

My dealer has Delta 100 in 13x18cm, and it may be available from Ilford in 5x7" also.

Just to add my two cents, like most people here, I have nothing but praise for delta. I find it gives me the kind of smooth, nearly grain-free look without the clinical, lifeless aspect that seems to happen when I use Tmax (stressing when I use Tmax). I also find it a touch easier to handle and more idiot-proof than the Kodak product, which is great for an expert like me
For the most part, its still too smooth for the majority of the work I like to do, where it seems my preference for traditional emulsions takes over. But out of the new tech emulsions, its the one I reach for. I usually soup it in.... (wait for it) Rodinal, 1+50. Works great for me, especially in 120.

I would not be crying over owning 60 rolls of Delta 100 - you certainly did not buy any swamp land in Florida, if you know what I mean!

Morten Said:

"It's my main portrait film for B&W in the studio.
I rate it @ 100 and develop in Rodinal 1+50 for 12 minutes (11-14 depending on the contrast I want)."

Daniel...two notes above me, said he uses rodinal 1:50 7 min 45 sec.

Is the difference the agitation time?

I've developed a bit of this stuff for some of my colleagues and almost always used either D-76 1+1 or XTOL at varying dilutions from 1+1 to 1+3. Both developers are great combinations with this film. If you consider a little more shadow detail and somewhat better highlight separation advantages, then I'm compelled to give the nod to XTOL at 1+1 or 1+3 as the best I've tried.

IMO Rodinal defeats the purpose of this film which is to deliver among the sharpest and and most fine grained images available from a film in this speed class. Rodinal will not do this for you. If it's sharp edged grain you want, then use another film with this developer. Chances are you'll prefer the look of a more traditional slow to medium speed film's grain better. Don't waste the Delta 100 on it. But don't take my word for it. You have plenty of the stuff. Try it and make some side by side comparisons and see for yourself.

Ilford Delta 100 is really nice film, I got ok results with HC110 but I have not tried it out with Rodinal yet.

And I'll add in another time with Rodinal 1+50 - 8.5 minutes, with 5 inversions each minute for first three minutes, then one inversion per minute thereafter.

I shot it at EI100 in my Iskra, and the negatives looked great, very sharp with nice tones and detail.
