    Colour Card Image Matching

    jacktorrance Level 1

      Hi,

       

      I have a series of photographs taken with colourcards next to the content. The colourcards are dark grey, mid grey and white.

       

      The photographs have been taken with exactly the same setup although when I use the eye dropper tool in PS the values of the colours are slightly different. I suspect that light might be bouncing off different things in different images, the minor differences aren't that surprising. However, I need to make the colour card RGB values in all images exactly the same, and automate the process as there are hundreds of images.

       

      Can anyone help with a workflow? I can't get my mind around how to apply the settings to all images so that the RGB values come out exactly the same for the colourcards every time.

       

      Many thanks in advance.
