I found the 80A filter peaks up the Cyan too much which causes saturated red when inverted.
So I wait for a blue sky day and point the rig in opposite direction to the sun. -Blue sky seems to be more gentle than the 80A
Setting white balance on the camera is not relevant, as I take a raw file to ufraw to make a 16 bit TIFF and on to the contrast stacker.
I found it is critical to adjust the Histograms in the camera so that there is almost no information at each end.
That is not easy to do on the 3 channels, a few test shots are needed, adjusting the exposure carefully.
When I get a good camera shot, I do a color balance of the neg in ufraw before it is inverted,
as I found that minimizes the color balance needed when it is an 8 bit positive image.
If there are any values at the ends, they will be either saturated or lost when the neg is inverted and it will be no good.
Red is the troublesome one.
It looks like your sample image above maybe had some saturated red which became cyan.
Re-photographing the neg is quite a chore and my method is only suitable for a few shots per session - it sends me nuts
Scanning is a lot easier.
But my V600 scanner is acceptable only on 6 x7, 6 x 9 negs and it is no good on 35mm.
I just realised that it was a total pain and gave up. I started shooting film to avoid post processing and not to make it into a nightmare
After adjusting the tray height to + on my V700, I started getting really good 6MP scans. I'm more than happy with them, since they are enough for an A4 print. They come out to be at around 275-250dpi.
For me, if I ever get an awesome photo that needs more dots etc... I will get that oddity professionally scanned.
But if I need bigger negs I use my hasselblad and I get 24MP scans. Here's a scan of E100VS shot (might be a wrong thread for it since it's 35mm photo
), but as you can see from this 2 pics, to me the resolution is sufficient.
I also find the tonality in highlights and shadows my better from scans on my V700 compared to my K5.
In my opinion if you are after preserving the look and colours of negatives, being colour or B&W, get a film scanner. Something like V600 or V700 and you will save yourself lots of time. With V700, I can scan 6 photos at a time
