Use some codes to modify photos.



#declare p_modify1 =
pigment{
    pigment_pattern{p_original}
    pigment_map{
    #for(i,0,255)
        [i/255,
        bumps
        scale 1/input_wide_res
        scale 4.8
        rotate <0,0,20>
            color_map{
            [0.2+0.6*(1-pow(i/255,1/3)) rgbt<0,0,0,0.1>]
            [0.2+0.6*(1-pow(i/255,1/3)) rgbt<0,0,0,0.9>]
            }
        ]
    #end
    }
}

Another test

#declare p_modify1 =
pigment{
    pigment_pattern{p_original}
    pigment_map{
    #for(i,0,255)
        [i/255,
        bumps
        scale 1/input_wide_res
        scale 0.8
        rotate <0,0,20>
            color_map{
            [0.2+0.6*(1-pow(i/255,1/3)) rgbt<0,0,0,0.1>]
            [0.2+0.6*(1-pow(i/255,1/3)) rgbt<0,0,0,0.9>]
            }
        ]
    #end
    }
}

VERY cool. I like both images. Thanks for the interesting code.

With some appropriate functions maybe-- to split the original color image into 3
functions-- you might be able to do all three *color* channels in a similar way,
for a painterly 'pointilism' effect.

I ever split it into 3 functions. But re-composite them using this code the
result is weird.

I often using it to create two color image.

This time using quilted

#declare p_modify1 =
pigment{
    pigment_pattern{p_original}
    pigment_map{
    #for(i,0,255)
        [i/255,
        quilted control0 0.5 control1 1
        scale 1/input_wide_res
        scale 4.8
        rotate <0,0,20>
            color_map{
            [0.2+0.6*(1-pow(i/255,1/3)) rgb<0.24, 0.167, 0.167>]
            [0.2+0.6*(1-pow(i/255,1/3)) rgb<1,1,0.9>]
            }
        ]
    #end
    }

I agree to Kenneth - very cool methods - and thanks for the code.
With 3 functions I got this nice image ("glasses" from Hall of Fame as input).

YES! Very impressive. You picked a good image to work with, too, nice color
values.
