I finally managed to use the old Cambo SC monorail to make some 8x10 colour pictures of the bark of the redgum in the reserve.
I mucked up one exposure---the first one--- as I'd forgotten to take off the yellow filter on the Schneider Symmar 210 mm lens that I'd been using for my black and white exposures.
The next step is take the sheet film to Atkins Technicolour to have them to process the negatives. That service will not be cheap-- probably around $16.50 for one sheet of film. The next step is to scan the negatives myself with the Epson V700 scanner.
I did two abstractions of the peeling bark in the open shade:
I'm not sure that 8x10 colour is an economic proposition or that it is worth the expense. I had the sheet film in the fridge and I needed to use it before it expired.
