Thanks Maris the deceptive bit is those shots were taken using a BTZS Profile which originally was for APX100 and a series of tests and short cuts at Steve Nicholls darkroom he modified the film curve which seemed to be spot on.
Soon it showed promise but had shortcomings, You're summing up "light leak, agitation artifact, camera body flare, edge fog on film .... ?
it was all of those at separate times,When you have not done any 8x10 at all your head gets in the way,i thought for sure it was light-leak but centered mainly around the lens boards made by me 6mm MDF. I used bookbinding tape and put 500 gm of extra weight yet still it persisted.
This film is Fuji HRT double sided
later that day we went to Hindmarsh falls just before a lightning storm and heavy rain this was attempt 4 or 5
The air was crackling and my wife was staying in the patrol yelling out hurry up ,I had just packed up when Boom came the thunder and lightning!
The fallen tree is no longer there,I don't know what happened to it possibly set on fire LOL.
The prints from these were all tests for a trip to Kangaroo Island Which was a disaster, I told Steve I had put some stuff up and one of his comments with X-ray film was 'You never know until the next exposed neg.'
All of these examples are scans of prints using View-scan on a HP Scan-jet 7400C
