This is a first attempt at shooting and scanning Efke R25 black-and-white
transparency film. I realize that I have a long ways to go, and this might
not be the perfect composition.
However, for testing the film, this was about as difficult as it gets!
HARD blacks to HARD whites, but the Efke seems to have good
latitude even in horribly high contrast situations. Shot at ISO 12,
to try to hold back contrast as much as possible.
Used Sunny 16 rules for pure white and pure black, and averaged
the difference. Opened up a stop as I was afraid the falls might
turn out too dark, and got lucky on that.
I'm looking forward to using this super-low-grain film in better conditions.
Wow, it lost a LOT of pop in the upload, seems to affect this type of image.

Haha! I was waiting for that, Attila! 
Bear in mind that this is an experiment, working with black and
white transparencies. I'm actually trying to see what kind of latitude
for light there is, how it scans, and how "workable" these
transparencies are.
But don't despair, Attila...I DO have some color images from that day.

I did set the meter for ISO12 and then had it developed as ISO25.
Honestly I don't know the physics as to why this creates less contrast,
but I was advised to do so by Mark, the owner of dr5. Their process for
transparencies from black and white films gives results that are
highly "tuned" to recommended ISOs for given situations. Mark knew I
was going to experiment with a super-high-contrast, so he advised me.
So, I guess this basically would be a "pulled" image, as opposed to a
pushed image.

Here's some text that I received from David at dr5:
My text:
Hi David: I'm in the process of sending in three rolls of Efke 25 -
two of them to Dev-1, and one of them to Dev-2.
In reading the description of how Efke R25 "comes out" in
the dr5 process, there's a statement that for higher
contrast situations one should shoot below ISO25. I decided
to try it out in a VERY high contrast situation, by hiking up the
Skokomish River near my town, and shooting the white water
and dark rocks. I'll be curious to how it comes out. I shot at ISO12.
Are there any other recommendations you can give for good
results in high contrast situations? Most of my black and
white transparency shooting will be in high contrast
situations (mountains/snow/ice and rivers/rocks/rapids, and
(hopefully) finding enough dynamic range in something like
Efke R25 for black and white transparencies without resorting
to bracketing.
David's reply:

You can work with any film and lower the contrast. Shooting at a
lower iso is the proper method to control it.
Films like plusX, delta100, FP4 do well under high contrast
situations in the dr5 process without lowering the iso to extreme.
Efke25 is really quite nice when shooting at iso12 or iso8,
especially for the high contrast scenes you are mentioning.
On the other hand, we have published that if you go higher
than
the recommended iso for the films, then the contrast increases
quickly, as when we push these films under dr5, the contrast
is affected.
We have limits for some films where we won't process at all if a
certain iso is exceeded. It's just too hard to give good output in dr5.
Note the various films and recommendations here:

thanks man. this is such an interesting topic, it maybe should have its own thread. it seems the variables are not only pushing/pulling, but film type and developing process.
in my ignorance, pushing/pulling was solely light determinative. now i realize there are contrast ramifications as well. i am also totally ignorant of the IQ effect different developing processes have--in fact even as to what the choices are!
anyway, i honestly didnt mean to hijack your thread, i just found the ancillary topic fascinating. you used all the above to really nice effect, now i am even more impressed!
