Sandy Cove Cape Leeuwin Augusta Velvia 4×5 Tetenal

Cape Leeuwin Augusta

Sandy Cove Cape Leeuwin Augusta Western Australia is available as a 16×20 inch photograph and larger.

Sandy Cove Cape Leeuwin Augusta was developed in Tetenal E-6 in a trial. Cape Leeuwin Augusta is a rocky granite promontory renowned for the location of the Cape Leeuwin Lighthouse. This rocky finger that points into the ocean is seldom without wind or swell. There are tiny partially sheltered coves complete with their own miniature  beaches. Their sand varies from coarse yellow granules to sand interspersed with finely ground shell grit. I believe the colour of the sand is this particular cove is partly due to mineral carried by ground water leaching out into the area. In the foreground a spring water swirl can be seen, its flow originating from beneath the sand. The film was 4×5 velvia, no colour filtration, 90mm Grandagon lens.

Tetenal E-6 Chemistry and Velvia 4×5 Trial

My initial trials of Tetenal E6 3 bath kit on Velvia 4×5 50ISO were successful. However, I intend to make the following modifications to the  procedures set down by Tetenal.

What I want:

  • a one shot process that gives me a maximum film yield of 12 films per 1000ml Tetenal working solution.
  • ability to process 12 4×5 sheets of film at a time.

Modifications to Tetenal  Procedures

  • First, I will be using a one shot technique, rather than the re-use technique. This will eliminate the need for  adjusted development times from chemical activity depletion.
  • One shot has the potential to minimise the overall process time. It also avoids the risk of cross contamination of chemistry.
  • One shot avoids the problem of volume depletion of solutions, especially of the first developer.  Incomplete return of all solution is no longer a problem.
  • I intend to use the chemistry to obtain the full yield of films as recommended by Tetenal.  That is 12 films per 1Litre of working solution. This is equivalent to 48 sheets of 4×5. 4 sheets of 4×5 = one 120 film =one 35mm 36exp film.
  • For the developing I will be using a Jobo CPE2 processor. A Jobo 2550 drum holds 2 4×5 reels, with a maximun of 12 sheets of 4×5.
  • The maximum volume of solution for my Jobo is 600ml. This will ensure all film is in contact with the solutions during agitation.
  • I will be using only 250mls of working solution for each batch of 12 sheets. According to Tetenal, 1000mls of working solution has sufficient development activity for 48 sheets. By proportion, 250mls has enough activity for 12 sheets.
  • Each working solution, once made up according to Tetenal’s instructions, will then be further diluted with water to make a total volume of 600mls.
  • This act of dilution may require additional processing times which I will need to test. So far, my development times have been based upon visual inspection of my own film tests with a grey card.

When I get my next batch of chemistry I will test the times using my new proposed dilutions. If it all goes to plan I will post the results.
