The first image on the left is my original image, next is the one image that I slightly corrected to make it look prettier and last is my photo that I totally changed in order to bring across some sort of emotion having to do with my topic.

The last photo (the one I changed the most) represents to me how one day the sky will permanently be a shade of green and gray because of pollution. Also, this picture shows what is normally a very beautiful scene including artwork, but because of pollution the art has become dark and has lost its original shine.
