Depth of field is one of the neatest ways we can exercise creativity in our photos. How much your subject is in focus will have a great affect on the general mood of your photo. Have you seen the photo of a cityscape at night with the headlights blurred to show the movement of traffic? Or the shot of a field of flowers with one single bloom in focus? There is a reason photographers choose certain depths of field to their images, and that is usually to evoke a certain mood or feeling from the viewer. Traditionally, portraits of people tend to have a wide aperture (along the lines of 2.8, for example). The reason behind this is so the background is beautifully out of focus and we can see our lovely subject a little more clearly. The opposite is often the case with landscape photographers. They often use smaller apertures in order for their photos of a landscape to be crisp – all the way from the flowers in the foreground to the mountains in the distance. And of course there is every setting in between! Here is an example of two different settings:
Do you see how not only that little number on your setting can affect focus, but the actual real-life setting in front of you? I for one, think it’s pretty neat. After all – if you aren’t getting enough blur for your liking, put your subject far from their background for an extra “push.” You are in control! Just remember that :). Have a great holiday season, everybody! Now let’s see if you can get a beautiful shot of that Thanksgiving turkey before everyone digs in, eh?
