Reply To: Border effects in Indesign

You can create a monochrome (pure black & white) mask in Photoshop and place that in InDesign on top of the photo. Then make the black pixels white and the white pixels transparent — these are just color fills, in InDesign. But these work exclusively with monochrome bitmaps.

It means you have to create the complete mask per photo to size in Photoshop; and, unless you make a lot of different masks, you would need to re-use each one a couple of times in your ID doc.

All in all, use Photoshop. (Or perhaps Illustrator instead, as you can convert a rectangle to scratchy drawn white lines with that.)
