In order to make this picture i used many pictures that depict partners and health organization. Then i organized the pictures to the desired size and place. The layer reveal all allows us to brush off the edges in order to give the pictures a more naturally mixed look instead of the regular rigid outline. Then by using the brush tool and black and white colors, i was able to brush away the edges and create the final product/collage.This picture uses this technique as well as the opacity selection and the duplicate layer tools in order to provide the best possible collage.
