im new to photoshop and what im trying to do is to use a circular selection atop this jpeg i have and inside of it to create a radial gradient where the parameter is saturation. so i want the center of the selection to be at original saturation, and then have sat fade radially and gradually up until the circles boundary to maybe 40% sat. i have no idea if that would look good, but nonetheless, does anyone know how to do that? (or in gimp?)
