[pure-silver] Re: Stand developing/Efke

I think I was the guy who started all this with my post about developing Efke 25 this way in 1:100 Rodinal for 20 or 25 min. Don't know about any other film, but...

The tones do not appear compressed (read flattened?) to me. If I had to try to put my finger on a particular characteristic that might be associated with the stand technique, I would mention the nice combination of very high accutance and very fine grain combined with normal contrast.

For this film, I will develop this way every time unless I find something better.

I agree with Richard, stand development is useful to compress the total
scale of a very contrasty subject.  You see this method described in
articles on the Zone System.  It should not be used as a general purpose
technique.

Well, I gave it a shot - Rodinal 1:100 for 30 min. at
about 72 deg. Strong agitation for the first 30-40 sec.,
then let it sit.

Most of the frames turned out OK (if a bit thinner than
expected), but a few frames (with wide expanses of clear
sky) showed sprocket-hole streaks. Not pronounced, but
enough to ruin the frame. Seemed inconsistant thru the
roll.

Not sure what to think.

  The sprocket hole streaks are typical of stagnant
development. There is some convection of the reaction
products of development when the film is vertical in the
bath. Since there is no development going on at the sprocket
holes there are not reaction products produced so there will
be an area under them that is somewhat higher in density
than in the adjacent spaces. The effect is present all over
the film but may not be noticable where there are not small,
well defined, areas of significantly high or low density.
You will find the opposite adjacent to small, dense
highlights, where there will be streaks of lower development
due to bromide.
  Generally stagnant or stand development is done with the
film horizontal. The reaction products accumulate in the
vicinity of the development then and the effect is of
lowered density of highlights and exagerated adjacency
effects, which are controlled by diffusion in the emulsion.
  Stand development can be useful for some special effects
but IMO is not good general practice. Frankly, I think Danny
was lucky.
  Nonetheless, the pictures are excellent.
