For This picture, I cropped the image and rotated it so it became straight.
For this image i posterized the picture, selected the different shaded grey areas and changed them to different colors.
For this image, i duplicated the moon, changed its color, added a dolphin and a globe, added a lens flare, and motion blur to the text.
In this photo i changed the Hue/Saturation to make it look more bright, blue, and green
In this picture i used a foreground to transparent gradient on the type to make it look like it is fading away.
For this photo I created a background layer and filled it with black. Then i created a layer mask on the stop sign layer and painted the background around the sign.
For this photo i made three copies of a "Charlie and Me" poster and pasted them onto the image. I then used the distort feature to make them look like they are actually on the green area.
In the photo i used the healing brush to select an area around the birds and paint over them giving it the effect that they are not there anymore.
