I cant answer your question, but there\'s a film scanning forum over at www.dpug.org. You can try there for help.
Thanks RM, I have registered on there and done some initial digging.

lenticular11,
I will give my two cents. Scanning color slide film & neg color film is a challenge.
The shot seems a bit underexposed in the shadows but that might be your scan
Yes it\'s certainly heavily underexposed in the shadows but I know from way back not to overexpose highlights in slides, hence I erred (too much) on underexposure.
I\'m not sure of your exposure technique, but I will give you mine.
For Velvia, I measure the brightest spot & open it up two stops from there
In that scene, the bright spots in the sky might be a problem for containing the shadows & highlights
Agreed! The image in question doesn\'t even appear to be in focus! Believe it or not there are others in that roll (same scene) where the colour cast is even worse and the lighting more dramatic again.
For scanning, whether using the Epson s/w or Vuescan.
I do the absolute minimum in the scanner software.
In some cases I will also do a RAW scan w/Vuescan as that gives the complete unfettered output from the scanner.
This gives me the best possibility of containing the dynamic range.
With the Epson S/W, after the preview,
I use the histogram & move the sliders to just past the dark & lightest ends
I then adjust the output values to 0 & 255.
This gives me everything & a slightly flat scan.
Yes, that\'s what I\'ve also been doing with Epson s/w , with the addition of some slider-work to try and iron out the mauve sky tinge.
I have used Vuescan and continue to do so with 35mm, however it has a hopeless user-interface, hence for MF I find Epsonscan more straightforward. I have explored the RAW option in Vuescan previously, but not with this film.
There is no magic in the scanner software that can\'t be better controlled in Photoshop
Agree and even Lightroom (not my normal editor) has impressive PP functionality for further highlight/shadow control.
Having said all this, I realize you shot this with a GA645 & no doubt hand held.
That precludes some of the above shooting suggestions.
Not sure what manual modes that camera has.
The camera was too new to me to do anything but use AP and check I wasn\'t shooting at too low a shutterspeed.
A \"safer\" way with handheld shooting would be to use either Portra 160/400 or Ektar.
These negative films have more dynamic range then transparency film.
Another choice would be Astia or Provia transparency film as it has an extra stop or so of dyn range.
My Dad shot slides all of the time and so that\'s what I gravitate to. I loathe getting neg prints back that are often poorly exposed at print stage.
I love shooting Velvia 50 but I try to choose the film that works best with the scene.
The trouble with a camera like the GA645 is that your are committed to the roll you loaded!
I have the same issue with my Pentax 6x7.
Adjusting out color cast is a challenge, more so for me as I have color blindness.
I have learned what the RGB mix is for various scene elements, sky, foliage, water, etc.
I also take a cell phone shot for reference.
I then use curves and/ or blending to get things right--- most of the time.
What ever you do, be methodical & keep track of what you change whether shooting or scanning.
I know film isn\'t free, but I will sometimes do different exposures & note what the results were.
I hope this helps
Dan
Thanks indeed, Dan it helps a lot.
regards,
David
Another attempt - different image. This one has better focus and I have spotted the dust.
