hi poohblah
i shoot paper negatives all the time
both 8x10 and 11x14 ( 7x11 too )
and it is a lot of fun.
paper is dirt cheep but film holders for 11x14
cost an arm and a leg - as john kasaian said ..
8x10 film holders on the other hand are very inexpensive
by comparison
i shoot outside as well as in a studio setting, and use fiber base paper.
i have graded agfa and a boatload of ilford, faux ilford, and kodak
to play with. i use a few 300ws lights in soft boxes and long 30+second exposures.
you can expose it a handful of ways - preflash works OK
and developing in spent paper developer and a water bath works
great too.
when i shoot outside i usually like overcast days - even light.
i usually sunny-16 and figure out my exposures from there
all being told though contrast can be a real drag with paper.
there have been some good deals for cameras ( both 8x10 and 11x14 )
in the classified section so you might be able to pick one up without a problem.
weight wise .. my 11x14 is a tank of a portrait camera on a rolling stand, and the 8x10 i use
is kind of heavy too, but not THAT bad ... i am not sure what tripod you have, but surveyors tripods
and a big sturdy head work well for big cameras..
you might test the waters by making a 8x10 or 11x14 box/pinhole camera. you can see how your paper
processes out and if it is worth the time and effort of buying a camera and lenses and film holders that will not be cheap.
jerseyvic here on apug shoots a lot of ULF pinhole images, maybe you can shoot him an PM ...
good luck!
john
