Delta 100 in Rodinal 1+25

[dweezil]

i,

 

I've recently come in to possession of some rolls of Delta100 and Delta400.

My normal films are APX100 for 35mm and FP4+ for 120 and I process them always

in Rodinal 1+25.

 

The guy I got the films from said that you can't develop delta in Rodinal

because of the Tgrain technology.

 

Is this correct?

 

What can I expect?

[christer_almqvist2]

NO, it is not correct. At least not for Delta 100.

 

With Delta 100 acutance is what you can expect, and a little bit of grain which will become

noticeable in homogenous areas like a sky without clouds, when you enlarge more that

12x.

 

I never liked Delta 400 in Rodinal.

Absolutely not correct, in fact Steve Anchell's Cookbook books specifically mention that he likes the look of Rodinal with T-grain films. I personally have never tried it, but there are definitely some who like it. Give it a shot!

[ted_gofferenger]

you can develop any B&W film in any B&W film developer

[larrydressler]

I love it in Rodinal 1-100 and 1-200 the 1-200 is full stand for 1 hour.

TMAX 100 is a T-grain film. It works very well in rodinal. But iso 400 T-grain films have grain problem, for 35mm film at least.

[chuck_albertson1]

That's odd. I just hung up a couple of Delta 100 rolls to dry, after developing them in Rodinal 1:50, and they look great.

I think there are much better combinations in 35mm Delta 100 and Delta 400 available then a Rodinal development, to take maximum advantage of the Delta modern grain technology. Normally a 35mm 400 iso Tgrain film is used to minimize the grain and take advantage of the maximum speed of the film.

Well, each para-amino phenol developer will cause speed loss (1/3 -2/3 f stop), will emphasize the sharpness (wich is already extra sharp with each Tgrain emulsion) but will add some extra grain.

 

So a DD-X Delta 400 35mm combination will give slightly less grain then an iso 250 - Rodinal Delta 400 combination without any notisable difference in sharpness.

If you're going to a larger film format a lot of these things are less important.

 

If you have the right equipment in 35mm (Leica, Zeiss lenses) you can work with slower speed films (or even Tech Pan films) and make them look like a medium format enlargement. However it's much easier, less critical and less complicated to have the same result with each medium format camera. (Except from carry the extra kg's and missing the right pictures because you can not work very fast with most of these camera's).

 

But it's just depending what is your style of photography. Any landscape will not walk away, just the light will changes in a few hours, maybe sometimes in a few minutes but will give you the time for a nice composition with a M.F. or L.F. camera with tripod, calculate the right E.I. a.s.o.

 

In candid street photography or in the theater the right picture is depending on fraction of seconds.

Different situation: So different equipment and different type of film choice.

Balderdash! Delta 100/Rodinal is my principal film/dev combination but I usually downrate it to 50 ASA and dev in Rodinal at 1:50, 20 C, 8 minutes - that's for a diffuser head enlarger.

 

I suspect your man was confusing 'new' grain technology with chromogenic films such as XP2.

[laurentvuillard]

I have never been happy using delta100 at 100ASA with 1+25 rodinal, I prefer ID11 but it looks as others made it to work at a higher dilution and different ISO setting. I use ID11 20 degrees 8,5min 30 sec continuous inversions then one inversion every 30sec.

Good luck

Delta 100 (EI64), Rodinal 1+25, 68F, agitation every 30 sec.

 

Pls, draw your own conclusion.

[larrydressler]

Here are some of Delta 100 in Rodinal 1-200 full stand 1 hour.

Why, Larry?

 

Lynn

[larrydressler]

Just because I had never tried it before.

[christer_almqvist2]

Stan,

 

Larry,

 

what size negative?

[stan_belyaev]

Konica hexar RF, 35mm film

[larrydressler]

35mm Nikon N90s 17-35mm WA zoom

[profhlynnjones]

Hi again, Larry,

 

That has to be the best answer I've heard for awhile.

 

Lynn

 

By the way, I tried Bill Mortenson's "trick", of developing film in the refrigerator for 4 days for the same reason you did your still developing. My response was, "OK, now I've done it".

I always figured that there must be something else in this world besides what people tell me is right to do. :)
