I have around 70 sheets of 8 x 10 C41 Kodak 160 NC to process. Many contain large areas of open sky and subtle gradation The lab I used to process the first 6 sheets was unable to attain even densities in the skies and I have lost those images due to the heavy mottling of the silver that has occurred (we think) during agitation. The lab tested grey card exposures again and again and could not achieve even density. They eventually gave up and I now have to find another reliable solution.
Can anyone, from experience, suggest a lab who could reliably get the evenness required across these extremely even toned 8 x 10 sheets?
I will happily courier to the USA or the UK to find the right lab.
