For the depth of field project, we used low f-stop matched with a high shutter speed to make the object in front focused and the objects in back out of focus. As you can see, the object in front stays in the same amount of focus in all 4 pictures but the background gets more infocus due to a higher f-stop and a lower shutter speed.
Chalk Drawing: For the chalk drawing I made it look like a bucket of water was being dumped onto Lexi by using perspective.
