VS: Home-made POP (was: Astronomy Pinhole Picture of the Day)


Thanks for showing!
Lovely colors, are these scans of fixed prints? I never got such saturated colors after fixer.

Well, maybe I wasn't exposing long enough, but some of them were all day (8 to 10 hours) exposures. UV index never gets very high in Finland though, maximum will be something like 5.5 - 6.5, contrary to 8 - 9 or so in Southern Europe (& US southern states I guess).

The images may change color in the fix but with extensive exposure they do
not fade.  It may be you are not exposing long enough.  You can check out 4
images here, but please excuse the layout--I did it quickly:

Yes it's fun, and you need verrry contrasty negatives (the process records
each and every step of Stouffer 21-step!!). But the beautiful printing-out
image tends to fade badly in the fixer, unless you use a toner. Maybe a weak
toner, then a weak fixer, a weak toner again, and so on... carefully. You
can also add some silver nitrate solution onto the paper to make it faster
and deepen the "blacks". And, of course, the paper can be thoroughly fixed
and washed *before* the exposure, to remove the silver, and then treated
like a salted paper, to make "salted POP".

Here are some of my experiments with outdated papers (POP & lumen):

VERy cool picture.

I teach this process--making BW paper POP or printing out paper--in my
Experimental Photography class every fall.  Until you do it, it seems
impossible.  I have them do photograms outside, laying stuff on top of the
paper under glass, juicy stuff, too, because chemical reactions will produce
all kinds of different colors.  It is a cinch to do.  A 4 or 5 hour exposure
under direct Montana sun produces brilliant pinks, oranges, yellows, mauves,
browns, you name it.  Into the fixer when done--no need to worry about
taking it out of the contact frame and walking to the darkroom with full
exposure sunlight because it is very slow this way since no development
occurs.  Fun stuff.  BUT I have never exposed it in the camera before.

Nice to see Justin Quenell still doing pinhole, too, as I show his work in
slides in that class.
