(Photoshop) Season Change Image

Season Change with Photoshop CS

Open your image, add channel mixer and adjust parameters as follow:
Red -50, Green +180 and Blue -50


2. Create a path around my model
4. Make selection around my model with 10 px feature

5. Add layer mask
6 Fill in layer mask in order to hide channel mixer effect and ensure that you use black as foreground.

7. Deselect the selection

8. Correct some details by utilizing Brush to smooth an edge of mask. For example, I use brush to smooth edge of her hair and background. Try to adjust with Brush Size, Opacity and Flow in order to correct the detail.
Wow you will get the season change image.
