I have a large box of disordered negatives and I would like to scan them
into photoshop to see what they are prior to scanning some of them with my
newly acquired Plustek film scanner. I do not want the flatbed scanner
set up to scan them as negatives as it is far too time consuming. I have
already tried scanning the negatives into photoshop and used the image,
adjustments, invert command and curves etc to adjust the colour. However
this has not been very successful. and it is too time consuming. Is there a
quick way of producing recognisable positives from negatives? It would be
great if I could scan a lot in and used some action to convert them to
acceptable positives.
1) Scan (or otherwise digitize) one negative with pure clear and dark areas
- a bit of leader will do. Also include a typical image in the scan.
2) Create a new action and click the record button.
3) Use the eyedropper tool in curves to set these as the black and white
points.
4)Then invert the RGB curve so that it slants in the other direction.
And just how does that remove the orange mask from color negatives?
The white eyedropper maps the orange mask to white, removing the mask -
inverting the RGB curve then inverts the negative. Other methods that use
auto levels will fail if the image does not contain pure white or black
