I use the method of positive overlay to synthesize two pictures, one is a white cloth picture, the other is a dark picture (take black as an example)
the principle of positive overlay is that multiplies the pixel values of the two colors and divides them by 255 , so all colors and black are overlapped, and the final result must be black. The darker the color, the lighter the texture of the resulting image

what method can be used to synthesize dark pictures and white pictures into while retains the texture of white fabric pictures?

as shown in the following figure
