CD4-LC low contrast developer for scanning

[Alan Johnson]

Mixed results with camera shake and low resolution from a hand held 28-90 consumer zoom, with some streaking attributed to 3 min agitation intervals.



The King Mono 50 film itself was OK given 20% less development cf post 72 Sept 15 24.

The 2EZS test shows the +2 stops negative has a lighter sky (lower CI) and darker foreground (higher CI) than the normally exposed negative (attachment).

This is consistent with an S-shaped curve for this sound recording film in CD4-LC.

Whats especially apperent in that comparison is the difference in the hue of the negative. The one on the right is very warm in tone. Do you recognize this also in the real-life negs? I'd be surprised if a 20% reduction in development time would give such a pronounced difference in hue.

 

[Alan Johnson]

The difference in hue is partly due to a grey ND filter on top of a brownish negative. The negatives are less brown than they look on screen. I don't think this alters my conclusion that they are the result of an S-curve.

No, I was just wondering. I agree the difference is a lot less apparent and perhaps nearly gone if you take away the viewing filter.
