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.
