[QUOTE="RadDave, post: 1610724, member: 234411"] Well, an image can be changed to grayscale in [I]Preview[/I] but takes a few steps: 1) First make a copy of the image (just in case); 2) Open the copy in Preview; 3) Either select the editing tool and then the 'Adjust Color' prism or open the Tools menu and pick 'Adjust Color' (see blue arrows in my attached screen capture); 4) Slide the Saturation indicator all the way to the left (see white arrow) - this converted my colorful CD cover art to B&W; and 5) Save the image to the copy and rename as needed. A more detailed explanation [URL="http://osxdaily.com/2013/09/30/convert-an-image-into-black-white-with-preview-in-mac-os-x/"]HERE[/URL] of the same directions. Dave :) P.S. if you need to 'batch process' a lot of images, then some type of automated routine or another image app might be a better choice? . [ATTACH=full]21093[/ATTACH] [/QUOTE]
