For this photo, we had to use depth of field. Depth of field is a way to make a subject stand out by making the background of the image blurred/out of focus. I decided to try this out to bring focus to a transparent subject that might get lost in a photograph with a busier background. I decided that to create this effect, a glass of water would be a good subject. I tried out a few different backgrounds, and I felt like the rocks provided a good amount of texture. I also liked how they could be seen in a warped way through the glass. The depth of field effect is done using the camera, so all I did in Photoshop was apply a slight blur to the background to enhance the effect just a bit.
