if it is deardorff that you have, and are looking for all the info about
there are a few places you can poke around ...
first --- you might contact deardorff .. the family is still making cameras and may have
historical information you are seeking ... http://www.deardorffcameras.com/
second --- contact ken hough, he is a deardorff restorer and historian
if it is learning and understanding how to use the camera ..
go to the library, go on amazon &c find the books mentioned .. or ansel adam's trilogy camera - negative - print
using a LF camera really isn't as hard as you think .. its just a box and a lensboard and film holders
the hardest part of using a large format camera might be loading the film, or remembering to close the shutter
before removing the darkslide .. using the camera really isn't that hard ...
processing the film ... you might look for ansel adams' - the negative
or read what people have written and questions asked here, and the large format page largeformatphotography.info
there is a TON of information to read and help you along.
don't get hung up on the small stuff and if you have trouble with one processing method
try a different one, until you find one you are comfortable with.
good luck !
