I am converting a color magazine ad to black and white for use in another publication. I chose "edit original" in the Links sub-menu in order to convert the CMYK product minis to grayscale in Photoshop, then I saved them with a new name. However, when I select a color mini to be relinked to its grayscale equivalent, the result is an extremely dark--almost black--image. However if I deleted the original color image from the layout, create a new frame and choose "place" from the file menu, the grayscale image displays correctly.
I am on a Mac and new to 5.5 -- my previous version was CS3, where I previously did not encounter this problem. Any suggestions?
Update to this question:
If I change an image from CMYK to grayscale in Photoshop CS3 rather than CS5, the re-linking works as expected.
Sounds like a photoshop problem or possibly an incorrect grayscale profile in CS5. ID takes whatever the K valuse are in the grayscale image and puts them in the black channel of the current CMYK working space, so the profile you chose during conversion would have some effect. Using overprint Preview would also give you a better idea of the output.
