Does anyone know how I can remove the film cartridge from a Nikon
Pronea 6i? The camera turns on, and it shows 25 exposures in the
readout, which also reads "Err" wheneever I turn it on. I cannot
advance the film with the shutter, and I also cannot open the film
door. I tried using the three-key combination to remove it, and that
also does not work.
I would like to remove the film without paying a photography shop to do
it for me.
