This is the best photo that I took today. The depth of field is very strong, the background turns into blur. It lets us focus on those two birds on the center of picture, so that we can see every detail of the birds. Also, it seems like these two birds were kissing at that moment. It makes this picture more dynamic and interesting.
This is a wonderful example of shallow depth of field. Remember that depth of field can also be extensive-meaning everything in the photo is sharp.
