  1. Re: Is this because of light leaking? Or overdevelopment?

    I vote for a light leak in the camera.

    If it were a development problem there would be a dramatic increase in contrast and not much fogging of the shadow areas of the image.

    The light leak...

    The most common cause of complete developer failure is fixing before developing. The purple tinge of the first solution gives some credence to the mix-up. We all think '"it can't happen to me," but...
  6. Re: How do I get a warmer tone when developing BW film?

  8. Re: How do I get a warmer tone when developing BW film?

    The second developer can be most anything. Very fine grain developers give 'warmer' results. So you could try Microdol-X (or whatever the Ilford equivalent is).

  12. Re: How do you clean your ground glass and make it brighter?

    Grid lines on Sinar ground glass can come off with a spritz of Windex.

    The page is for the f11 version of the lens, the text above states that coverage may exceed 100 degrees at f16.
