Some time ago I shot an image under studio conditions of a piece of flat art.
The image also contained a basICColor Grey Card and a mini-Gretag CC.
After processing the TIFF (having made a basic white balance using the grey card) I noticed that the image had a slight cast when opened in CS4. So, I used the Grey Colour Picker in Levels on the grey card and this successfully removed it.
Yesterday, I shot a detail of the same piece of flat art. But, because the client didn't want to waste pixels, I shot the grey card and CC seperately, but identically. I then applied the changes to the image and processed it.
However, when I open the image in CS4 I now have that same cast, but I don't have a grey card in it to use as a reference. So, if I was to apply the correction to the shot of the grey card, how can I then apply this to the art image?
Applying settings across images in ACR is simple, but how do I do this is CS4 to make the detail look the same as the earlier image?
