how Photoshop makes super cool metallic skin tones
Final effect
Original
1, open the original image, first use the HDR filter, the initial adjustment of the picture, so that the bright spot is very bright, dark parts are very dark, while the light, dark details are very obvious. (Now the HDR filter can achieve a high dynamic range effect on a single picture without having to synthesize the same picture with different exposures.) Then use the level tool to adjust the picture to enhance its contrast.
2, stamped layer to get a new layer, and then change the layer's blending mode to "multiply" to deepen the color of the picture.
3, switch to channel options, and select the red channel, and then apply the "calculation" command, get a new channel 1. Then choose the green channel, apply the "calculation" command, get the new channel 2. The specific settings are shown in the figure. Then, copy the ALPHA1 channel to the red channel and copy the ALPHA2 channel to the blue channel to get a bright color effect.
