Focus (bonus pic)


Focus, originally uploaded by lighthack.
I took this of my cat, Ivan, last summer. It is a good example of what a 50mm f/1.4 lens can do to create a shallow depth-of-field (DOF). Basically, when you open the lens aperture all of the way up to f/1.4 (meaning that it allows the light in through it's largest "hole" size), the field of focus (depth of field) becomes very shallow -- as you get away from the field of focus, everything becomes blurry quickly. Portrait photographers use these lenses often to bring attention to the focal area of the picture (like the eyes in this photo).
