Out of date colour negative film and image quality

[domaz]

That looks like scanner noise to me. Are you sure that's actually in the negative? Have you looked at it with a high power loupe?

Definitely not typical. I shoot a lot of expired C41 and 400VC's one of my favourites. I don't normally see anything like this from it, even if a lot older than 2008-dated film.

Tom:

That is Digital Noise in your scan. PM me the scanned file, I would like to look at in more detail.

Thanks

I bet it is a scanner issue. On the CCD scanners I sometimes get grain like this. I don't see it in an optical print. If a drum scan is done correctly it will scan with minimal grain like the optical print.

Here are some samples from a more controlled test, scanning with four passes on the Nikon LS-9000:







It looks as though 4 passes does improve image quality. However the 400 speed film still appears grainy; although one does have to consider the degree of magnification.

A next step may be to double check solution volumes and temperature in the Jobo, along with making optical prints (Assuming I get the Thermaphot running again soon) - for experimental purposes at the moment I could make up to a 16x20" print in the Jobo.
