Hi all Late night ebay'n after a few drinks and I now have a 8 x 10 pinhole camera. Well I was feeling a little remorseful cause I got out bid on a 8x10 camera, which are pretty rare around here, so I got the poor mans version. Its a Vermeer 8x10 with what I think is a .5mm hole and a focal length of about 4". Came with a film holder and more importantly some film (foma 100) Would it be worth me increasing the focal length? Seems for the film and diameter it should be around 141mm. Also I tried using photo paper and a flash with some flood lights. Im not sure the flash made any difference even after firing a nikon sb-26 32 times. Think 15minutes of flood light gave more. Do multiple flashing work with pin hole? Thanks, can only get better. Foma 100 @ 10mins. Developed in rodinal, with rotary drum, then a contact print. variable rc Paper negative, flashed and developed in centrabrom. Scanned and converted to positive.
