I was determined not to give up after my initially attempts with collodion in Scotland, as the process is so temperamental something basic but essential could have slipped my mind..
Unfortunately this was not the case I followed my notes step by step I started the morning but mixing the fix and filtering the chemistry.
I attempting to go over light leaking (possible) areas in the portable van with duct tape, but the heat that formulates in a dark van leaves the tape peeling off in hours.
I even tried using a different camera (12×10) to see if it was the dark slides of the MPP that were light leaking. Unfortunately non of these amendments solved the problem.
And whatever streaky (fogged/ chemical or light leak?) image was there initially later that day when the image was dried was destroyed by the varnish.
Some serious troubleshooting would need to be done, and for this I returned to my base studio in Essex.
Results are below:
10X8 Glass negative, f5.6 @ 4 sec hear you can see the streaky quality across the plate that I can only image is a light leaking and the image itself is faint and flat.
10×8 Glass negative, here is an example of the effect of the varnish under heat, at the moment I really fail to explain what has happened here and so I need to return to essex to discover more..
I have decided to test all variables that could have gone wrong in order to get to the source of the problem.
1) Add 15ml water to 500ml varnish// Also try new Varnish (for image disintegration)
2) More permanent solution for light tight portable darkroom// Trial indoor darkroom to see distinction (for light leaks)
3)Try other methods of fix: Potassium cyanide and Ilford Hypan fix
4) Re calibrate Silver bath
5)Indoor and Outdoor testing : Back to the darkroom
