In my digital design class we were asked to create a surreal image using one of our photos. I really don't like surrealism. I finally, at the last second, decided to make a picture of my sister's friend shooting a car with her hands and having the car explode, (Or at least try to do so).
I started off by cutting out an actual explosion from another picture. (Yes. I know. It seems like I'm cheating but I had to do a lot more to make it realistic.)
I then Blended the sides of the cut out explosion using the blur tool so that it didn't have that nasty cut-out look. I drew gray particles then copy and pasted them all around the explosion. i also gave the whole image a posterizing filter effect. (It made the main image and explosion fit together better.)
I added fog around the explosion. Gave the particles a motion blur shooting away from the car.
Finished photo. I cut out some of the bottom of the car's particles. I fixed the lighting and shadows using the burn tool so that I could make it darker on the back of the girl. Also gave the image a bleach bypass effect.
