Say I capture two photos of the same object. The second one with a light pointed towards the camera but away from the lens's optical path so the light creates bokeh. And in Ps, I want to stack these two images and, of the second image, I want the color of the bokeh to be changed; without altering the hue of the object.
I think the bokeh image must be on the top and how do I do this?
I want the color of the bokeh changed while the color of the watch kept intact. Actually I want to match the color of the bokeh to the watch, but that's not always wanted.
