Originally posted by timw4mail Generally, I'm doing a bulk scan of a full roll, or a strip.
1. I do a prescan to align the first frame, and adjust settings. Due to the fact that the scanner can feed an uncut roll through, I do not pre-crop any frames.
2. This is the first roll I've had real color trouble with, and I have not needed to adjust the histogram with other rolls.
Also, just to clarify, the (uncut, full roll) slides look good when examined in a backlit viewer, but the scanned dynamic range is horrid. CyberViewX is over-compensating for this, and creating awful color casts. Last I tried with SilverFast, all the slides looked okay, but they were just too dark, and hid a great amount of detail.
It is my belief from what you have said that you are allowing the software to take control in some auto way. I would strongly suggest that you take full control and turn all auto in all menus off CyberViewX should not be able to over compensate if you do not allow it to.
You can only really expect decent results from bulk scanning when all images are very similar i.e. shot at the same time. These images seem to be all over the place regarding light conditions and my overall impression is that you are allowing the software to try and do the heavy lifting. There is one really bad image there with what appears to be crossed curves Magenta Highlights and Green Shadows (Pentax camera on box) something very odd there.
I would suggest that you first try with a single image so...
What happens if you follow this workflow (for the moment forget about bulk scanning and just settle on one image). Check your particular scanner options but this should be somewhere close.
1. Select
film type
2. Select
Prescan Current Frame
3. Set Scan settings
Resolution - suggest trying 3200 first or somewhere near it(it is unlikely you will resolve much more detail but you should test to confirm
Bit depth. Select bit depth either listed as 48 bit or 16 bit mode
4.
Turn off all auto modes (Auto Exposure, Auto Balance, Auto Contrast etc.). Look in all menus for hidden auto stuff.
5. Prescan
5a. Crop
6.
Image adjustments from prescan goto
Curves or levels
Select and adjust each channel R G and B to a point just outside clipping black and clipping white
if required select the composite RGB to adjust overall brightness and contrast
The aim here to create a pretty much colour corrected image that may only need a little fine tweaking (if that!) in your image editor
7. Finally press the Scan button. This should scan your image including your RGB adjustements leading to an image that is suitable for minor post work
