week3 image editing/correction

This one i have done it with bitmap mode. PS: You do not need to adjust the color of the picture when applying the halftone effect.

Image >mode >bitmap > output:1200/use: half tone screem > Frequence 53/ Shape:line

Development after class:
Image>mode>bitmap> output 1200/use:half tone > Frequence 44/ Shape round

Image> mode> CMYK color > (creat new fill or adjustment layer) gradient map> doubt-click the gradient bar> doubt-click the color picker to adjust

inverse color version:
