    Re: C.P. Goerz Berlin D.R.P. Dogmar Age

    That would be a nice lens to cam up on a TRF Crown Graphic, and it would be a nice focal length for Big Shot use with a nosed-off cam.

    Looks to me as though it was hit with a light leak in the tank, right down the center of the reel. Inspect the light seal in the lid of the tank you used.

  11. Re: Is this bellows sag? Trying to identify cause of unexposed portion of image

    Looks like you loaded your holder into the camera from the top. The images projected on the film plane would be upside down. The bellows also sagged down from above and "dodged" the lower part of...
