Making Parts of a digital photo transparent

[bethreil]

I have digital photos of a bedroom I want to paint. The walls and ceiling are white. Is there a way to make the walls and ceiling transparent using Paint.net tools? My plan is to then make a transparency from the photo and put different paint samples behind it to see how different colors would look in the room. Thanks, Beth

Start by trying the magic wand. If that doesn't do it for you, try the "Color Replace" plugin in the Jesse Chunn plugin pack.
