Masking techniques and shadow technique and Changing background.










This is the original background image.








I added the image of the girl in the canoe and made a selection using the polygon lasso tool around her to make a layer mask.





I then added an Adjustment layer to lower the vibrance of the girl to -35. I then applied it as aclipping mask to the layer mask of the girl.

I then two copies of the image with the girl and the canoe and used the free transform to flip then and lower the opacity to 37% to make it look like a shadow in the water.

Lastly I cloned stamped the black part of the shadow because that wouldn't really be reflected on the water.
