1, unlock the original layer (double-click) to get layer 0.

2. Create a new layer 1, fill it with black, and then change its blending mode to hue. The effect should be black and white.

3. merge layers, ctrl+e? Get layer 0

4. Copy Layer 0 again to get a copy of Layer 0, and then reverse the copy of Layer 0? crtl+i？ ; The effect at this time should be the same as the negative of the photo.

5. Change the blending mode of the copy of layer 0 to color lightening or linear lightening, and the picture is almost white at this time.

6, and then choose another filter, choose the minimum value, see almost?

7. press ctrl+f? Just repeat it several times.
