    Re: Help with Carl Zeiss lens please!

    Really nice lens! This type of Compur shutter can be easily broken by trying to use the cocking lever when the little function dial is in the Z (=Time) or D (=Bulb) positions. And it breaks the other...
  2. Re: Can anyone recommend a sturdy tall carbon fiber tripod and ball head/pan-tilt hea

    Good tripod but there is a theory that the smallest leg section should always be extended. For us pessimists this means that the joint between the first and second leg sections is high up and out of...

    Re: Developer trays

    Instead of a photographic style developer tray I changed to a red polythene Kleenmaid dish washing tray from the camping supplies store. It's deeper than a tray for better splash control. Over the...

    Re: Film changing bag or changing tent?

    In a pinch I've used a big changing bag but to stop it flopping down on the film loading area I first put in the largest cardboard carton that will fit. This creates a "cave" for the hands to work in.
  6. Re: Contact Printing Large Format negatives with a Leica Focomat V35?

    Too true! Not only this but with the enlarger lens well stopped down any specks on the glass negative carrier, enlarger condensers or diffusion plates could also be imaged as out of focus blobs. One...

  10. Re: 300mm f5.6 TeleCongo Lens ... Which doesn't exist?

  30. Re: Proper Formula for Sodium Chloropalladite?

    Beware the nomenclature trap. Sodium Chloropalladite is not the same as Sodium Chloropalladate. The "ate" ending tends to be used for a higher oxidation state and the "ite" ending for a lower one.
