Today in Photojournalism class, we’re going to talk about several things, including the “photographic triangle,” composition and captions.
We’ll watch an Adorama TV video on exposure. We’ll discuss Brian Peterson’s book, “Understanding Exposure. And we’ll talk about depth of field and the concept of creatively correct exposure.

Photography basics: Blurring the background to reduce distractions


In this series of photos, you can see how adjusting the f-stop, or aperture, affects depth of field. In the first photo, the door knob is a distracting element. Lowering the f-stop number – or increasing the size of the aperture – reduces the depth of field. That blurs the background, making the door knob less distracting.
All six photos have the correct exposure. But which photo has the creatively correct exposure? I’d argue that it’s the last photo, which blurs the door knob the most.
