…on how to do selective colorization using Graphic Converter for the Mac? The only tutorial that I have found is for PS, which I don’t have, or by downloading and eventually buying a new program just for this one application, which I just want to play around with.
Gimp is free and can do a selective colorization by going into hue-saturation under color tools and reducing the saturation of the colors you dont want.(there may be a better way to do this but thats just the way i had figured out how to do it quickly)
So youre trying to just keep the color of one object, not just one color right? The only way that I know of to do that would be to select the object that you want and then reduce the saturation on everything else.
One way: copy the image into 2 layers, make the top layer B+W, and then add a layer mask with the object you want to keep being transparent in the top layer mask, letting the color version show through.
