First 3 pictures I edited in light room. For the first picture I put the "Cold Tone" filter on. The second one I just the "Old Polar" filter on. Then the last one I added the "Bleach Bypass" filter to the picture. For the collage, I just put the opacity down for all of  the pictures then just colored the background a light blue. My favorite one is the collage because it was the most fun to edit.
