Best settings to correct Grayscale (black/white) photos

[JessiRight]

The CCR option works well with my color photos... but I'm not sure which setting to use to correct grayscale and black/white photographs. Are there any auto-correct options for black and white photos?

Thanks!

Dear Jessi,

if you click and hold the Auto CCR button you will find several correction types.
You can for example use the auto (without CCR).
B&W images do not seem that complicated because they lack color.
However the scanner always works in RGB mode.
IF you view B&W images in RGB mode (e.g. 48->24 Bit) you will notice that there in deed is some color.
If you are scanning reflective material this might result form aging paper or a reaction of the paper to the light source.
If you are scanning transparencies these are from the emulsion which often show a slight blueish or greenish cast.
So in some cases a CCR function might be suitable.
This mainly depends on your preference.

If you want a pure B&W image switch to a greyscale output like 16->8 Bit.
But you should test how the different automatics work on the image.
A cast as described above might be present in the image the greyscale mode you would not see this.
Yet such a cast might still influence your image.

Kind regards,
Arne Ketelhohn.
