What's your preferred EI for TMax100 in D-76?

[Juan Valdenebro]

Thanks.

 

[Juan Valdenebro]

I mean: for MG paper printing for both soft and high contrast scenes with a single development time.

 

[Cholentpot]

I always shoot at 100 and develop 1:1 D-76.

Never had an issue. Like the look. I'll err on the side of over exposure because I'm a lazy Sunny 11 kind of guy.

Sunny 11 !
Great !
Close to my Sunny 8 1/2

 

[Juan Valdenebro]

I've used EI100 with 1+2, 13 minutes, MF portraiture in soft light. Great definition.
But I remember once I got 64-80 in 35mm, possibly 1+1, but I have no notes.
I'm doing (sloooooowly) a 35mm roll for stock...

Sunny 11 !
Great !

Sunny 8 is for expired film that sat in the attic and is being over exposed by two stops then developed in over used chemistry and dying fixer.

Same for me. Never had a problem. I've shot 20 year old expired TMAX at 100 , very seldom had problem.

Always box speed, in this film ISO 100, in replenished XTOL.

 

[Juan Valdenebro]

Hey Cholen!

Be careful with the latest Photrio education!
You may end up saying the works of Nadar, Atget, Bresson, Frank and Winogrand would have been considerably better in case they could have used replenished Xtol.
Those of us who are deeply satisfied, always enjoy intelligence and a good sense of humour.
That was a good one!

I'm up to roll 38 in a C-41 press kit rated for 8. Film still looks fine...if I squint.

 

[Juan Valdenebro]

Some (relevant) people say TMax films are great in D-76 but they don't really reach box speed: Xtol and TMax do it, of course...
I say even if TMax films are a third or half a stop below box speed in D-76, half a minute longer development is fine.

Wow!
Have you ever developed Kodak ISO100 slide film @50 in C-41 with a few extra seconds push?
It's worth it!

Nope but I now have 100 feet of Ektachrome 64 expired in 1997 to play around with.

That's great!
Possibly at 20-25 for portraits at the widest f-stops...
I bet you would like it.
By the end of the 90's EPP was the best slide film for it: that was Ektachrome 100, so I'd say your 100 feet are optimal too!
Have a good night!

Back to TMax 100 Box speed of 100, all developers including 76. But 76 isn't my preferred developer for it. As usual, everyone needs to do personal testing of film speed relative to their own specific development regimen.

 

[Andrew O'Neill]

64. D76 stock or 1+1.

This is what TMAX 100 curves look like in D-76 1:1 and stock. It can be rated at 200 if you develop for 48 minutes in D-76 stock.

Most other times this film may be considered to have a true rating of 100 and then you might choose to rate it at 64 to increase shadow detail -or- if you decide exposure placement by Zone System.

You do not need a yellow filter for blue skies with light clouds, so you gain a stop of practical speed by leaving the filter off.

48 minutes in stock, really? Looking at the Kodak datasheet looks to be around 7 1/2 minutes to maybe 8.

48 minutes seems a tad over developed.

You've stolen my thunder, Paul. However there is a figure of 48 mins in Bill's chart but I wasn't sure how this figure was arrived at but the MDC says 6.5 mins so 41.5 mins less so no small difference.

I am curious as to the explanation as well.Might there be a decimal point missing
as in 48 becomes 4.8 mins?

And that's how we finally discover Bill has a new ultracold light secret enlarger.

Thank you, Andrew!

back to E.I for Tmax 100, I shoot at 100 (with my newer AF bodies with Matrix metering, varies with older machinal bodies) I've used D76 stock but prefer 1:1, reason is that Tmax has very small gain to begin with, 1:1 is somewhat more of an acutance affect.

 

[Juan Valdenebro]

In past days Kodak recommended not to dilute D-76. In present days Ilford recommend ID-11 stock for highest image quality.
My take is the acutance, 1+1, dilute for one shot was a sales thing when it started: people used 1 litre for 10 films, but the "new" 1+1 recommendation with 240ml gives only 4 films from the same litre.

 

[Paul Howell]

Prior to Tmax films, I used D76 stock with most 35mm films including Plus X which benefited from the higher solvent ability's of 76 and Microdoal X. Along with Tmax and Delta films Kodak introduced Tmax developer, ILford DDX, Clayton F90 which were all acutance type developers. I've used D 76 stock with Tmax 100 and 400, I still shoot 400 and develop stock, with Tmax 100, 1:1, saying that my all time fav is MCM 100, only reason I stopped using MCM 100 is price, at $48 a gallon outside my comfort zone.
