Who is the dummy?

ME

Loaded up some Plus X with the intention of drowning it in Diafine, so, I should have shot it at.....320. So far so good.

Always use a yellow filter, so...I always meter at 160. 2 for 2

but.....

I set the meter to 320, and was thinking 160 at the time!!! Very bad....

And remember, I always have that yellow filter on my lenses, so the film was shot at.....640 :bang:

Now I have to figure out what to do with the film.....

Diafine, D76 or DDX?

 

[rover]

It isn't even math either.

That is a 2 1/4 ish stop push, if you figure Plus X at 125.

Has anyone taught film fractions before?

Now where did I see that sig line recently?

I'm old so I have an excuse for that kind of error, but you???

Diafine will be fine. I've shot loads of Plus-X at 400 in Diafine and you are not talking THAT much less light at 640. Should be no problem, especially if you are scanning and processing in PhotoShop.

I've been wondering how double processing might work out in Diafine. After running the film through Baths A & B, then into a water stop-bath for a nice wash... Then try to get as much water off of it as possible, and back into the A&B baths again for another go at some density.

This might not be too good for the health of Bath A, though, if the stopbath/wash doesn't remove most/all of the Bath B from the film. I've never tried double-dipping like this, but it seems feasible, and this situation of rover's might be a suitable occasion for it.

I used to do exactly that, as a way to rate Tri-X at roughly 3200 (high-school football games at night.) I read about this trick in a darkroom feature in 'Modern Photography' back in 1971 or 1972 or so, and used it several times. You don't get much shadow detail, but it does work (well, it works as well as anything works for a three-stop push!)

I don't remember exactly how I did it, but my vague recollection is that after processing normally through the two baths, I'd let it rest in a water bath with no agitation, then go back through the two baths again. I guess I never even thought about carryover of Bath B back into Bath A, but I don't recall it happening, either...

Seems to me that due to the water-logged film, it wouldn't absorb so much developing agent from Bath A the second time. But then, there isn't much undeveloped silver salts left for it to work on anyway.

Another interesting thought to boost density in Diafine would be to make up a more concentrated solution of Bath A... More developing agent that soaks into the film, the more developing that happens?
