      I received a file from a customer which has a grayscale image which apparently has been inverted. Does any know where Adobe hid this feature? Clear effects is grayed out and 'invert' does not seem to show up anywhere on the menus. I know how to do this in Quark but have never seen it done in Indesign. I need to place our scanned image so I need to be able to recreate the effect.

      Thanks,

      Mike

      I'm not aware of such a feature. Are you sure it was done in InDesign, what happens if you edit the image in photoshop, how does it look there?

      This is one of a number of XPress features I've never seen in InDesign. (Someone else might have found something like this, but I've never seen it, so it's not self evident if it exists.)

      I even tried fooling around with blend mode “Difference”, which does invert in a way, but it also subtracts gamma (brightness), so you'd be out of luck. Maybe someone who works with blend modes a lot knows a work around.

      But Photoshop is a much easier fix.

      In Photoshop go:

      Image menu > Adjustments > Invert

      If you don't have Photoshop and don't care to fork out the money, much cheaper Pixelmator or Acorn probably do the same.

      Good luck!

      Thanks for the replies. I would like to do it the same way that the customer did it. The files had the same image in it last year which was IDCS3. When I edit orginal from ID, it opens the grayscale image in photoshop. It must have been inverted in Indesign but I'm not sure how.

      There is a way of doing this; it's a 2-step process:

      1. just place a grayscale tiff in InDesign, color it (use the direct selection tool, the white arrow, to select the image itself not the container!) with fill color white (CMYK 0,0,0,0 or [Paper]). If you placed the tiff on white background you will not see the image any more…

      2. Select the container holding the image with the selection tool (black arrow tool) and apply fill color [Black]

      And it's done: you inverted your image!
