How do the different shadow/highlight droppers differ??

[hassiman]

Hi,

I have seen that on the top left control panel there are the Shadow/gray/highlight droppers and on the left side preview panel there is the small icon which also selects shadow and hilight in the preview image... but no gray.

How do the eye dropper controls at the top differ from the shadow/highlight controls on the side of the preview pane? Do the preview pane conrols automatically find the deepest shadow/brightest highlight areas of a previewed image?

Also, if one wants to make as linear a scan as possible for PP in Photoshop is it best to just back the deepest shadow from 0 to +10 or so and the brighest highlight from 255 to 245 and leave curves alone?

Thanks.

Dear Hassiman,

The difference between the two droppers is:

The one located on the main settings window is used to determine the white, black or grey points in every image, in case of having any color cast, you will also be able to get rid of them.

The one located on the preview window is used to display the actual lightest or darkest point in the image, it does not do any modification in the image itself (as you suspected).

Your question about the linear scan is not very clear, I do not quite understand what you mean by "as linear scan as possible"

Greetings
