Photoshop

In BTT class we learned about how to change a pictures background to either light/darker red or blue or green. It has different levels of colours to choose from. If you go to Enhance and go down to levels or brightness and contrast you can do so many cool stuff to your picture you can change a morning picture and make it seem like its night and change a night picture and make it look like its in the morning. not only that but if you go down to Enhance you can see more stuff there all of those are really cool too.
