How to change a picture's color in KeyNote 09?

[rickhorn]

I tried to find a tool in "inspector" but couldn't...I just want to change a JPEG file from color to black/white effect.

I know in Powerpoint 2011, I can simply click on the image and there will be several image effect selections on the ribbon. I couldn't find the same feature on Keynote 09.

Anybody can help me if I can change the color tone or gamma on a picture in Keynote 09, or I need to use other pictures editing software like photoshop to do it?

Thanks.

View, Show Adjust Image, change Saturation to zero. Obviously, result not as good as graphic artists get by Photoshopping color photo to black and white.

As karl878 said, or if you want to change the original image itself to B&W to reuse in ohter presentations etc., use Preview (in your Applications folder) and choose Tools>Adjust Color and reduce Saturation to zero.
