  1. Re: Black Spots on Scanned 4x5 Negatives. Arista Ultra EDU 100 ISO

    I see black spots on the positive which means white spots on the negative.

    White spots on the negative might be pinhole defects in the emulsion due to bad coating at the factory.

    Dust on the...

    Re: extra wide angle lens for 8x10

    The old Schneider Super Angulon 121mm f8 lens is often available at a low price and it does cover 8x10 with a millimetre to spare when straight on and centred.

    Re: Ionizer

    I run a negative ion generator during all my darkroom sessions and I don't have a dust problem. Maybe that's just luck or the generator actually helps.

  4. Re: Quartz Lens/UV LED's for POP Projection Printing?

    UV enlarger? Is this relevant? An enlarger that can do cyanotypes might be able to do POP.

  16. Re: What ever happened to rear swings AND tilts on field view cameras?

    There is a distortion in rectilinear camera images that is not related to camera movements. It arises because the edge of a plane image is further from the exit pupil of the lens than the centre of...

  18. Re: Cable release not fitting into socket on shutter

    This has happened to me twice. Each time I found a tiny broken off cable release tip still in the socket. A little screw driver was used to back the piece out and all was good.

    I've enlarged lot of 4x5 to 8x10. Even "enlarged" a 8x10 negative to 8x10 and then contact printed that same 8x10 negative by way of comparison.
    All the prints look absolutely superb but there are...
