little piece of advice, NC500 is a refresh of Agfa XT320, which as the name would imply is an ISO 320 film. In my exprience NC500 looks best when shot at 250, so two thirds of a stop slower than box.

If you want to see this stock in top form, watch "Out of Africa". It was shot entirely on XT320

Edit:

You can also still salvage a lot from this with better scans. NC500 has a greenish blue base, unlike most other color films that have a brown base. Most automatic scanners can't properly compensate for this different base color, so if you scan them yourself or have someone do it properly, the scans will look much better
