Excuse me, why does the radial gradient color of carema raw in PS cover the original picture?

I don't know what result you want. What do you mean by covering up the original picture? The description is not delicate and accurate enough. If you just overlay layers and make a gradient layer by yourself, use other blending modes.

ACR is used for photo retouching and color adjustment. If the picture is in JPG format, the operation will be irreversible. With the support of radial filter (range control), the image is retouched by photography.

For example, I want to highlight the bud, so I want to darken the surrounding picture, so I want to adjust the brightness, black field and white field on the periphery of the ellipse without affecting it in the circle, so as to realize the gradual change of adjustment degree. If you want to adjust the inner ring, select the inner ring.
