    I know this has been covered before, but I can't for the life of me find this via a search!

    How do you take a color .bmp and manipulate it so that only a certain section/portion of the image remains in color, while rendering the rest black and white?

    Thanks in advance for any insight!

    I guess I could always use the shape editor tool, or quick shape tool to outline the part of the image that I want to keep in color, select that shape and the rest of the image...combine/slice the shapes...and then set the transparency on the "background" part of the image to flat/darken/0%.

    Is there a more elegant method, or a method that will work much more efficiently should the image/shape that I want to keep in color be a bit more complex?

    Hi D-Rock,

    I would make a clone of the bitmap and then use transparency on the one on top. The attachment uses an elliptical transparency with a profile.

    Thanks, Soquili!

    Could you humor me and provide the settings on the transparency in your example? Elliptical...mix? Saturation? Beginning trans...end trans...which profile etc.

    I know, I know...I'm a pain!

    That would be double-dog cool.

    Someplace around here (I can't remember either) I saw that if you create an shape overtop of your bitmap (color black) and then apply a flat transparency, saturation=0 percent, I think you'll get a similar effect. You can then change the transpency to linear or whatever and the grey effect remains. I've never posted a jpg here before but here goes...

    Hi D-Rock,

    Here's another approach, based on techniques discussed by others in this forum.
