Photographing Depth of Field: What’s in focus and why?
Due Date: Feb 9, 2010, Beginning of class, on a folder with your First name Last name Project1 (FirstLastProject1)
The size of your aperture also determines how much of your image will be in focus. This is your depth of field. As the aperture opening gets smaller, the depth of field increases and more of the scene from near to far appears sharp in the photograph.
When you look at a scene your eyes only focus on a certain distance at a time. Only the subject of your interest is actually in focus. As your eyes move from different objects in your view the focus changes accordingly.
Make several photographs of a subject (your choice), but shooting outside in daylight will allow you to experiment with depth of field/aperture, without having to worry about lighting or shutter speed too much. Shoot an image where everything is in focus (large depth of field) and then narrow your depth of field so that the background is out of focus and only your subject is focused.
Look below for the effect you are trying to achieve, however, be creative with the assingment and think about the composition and what you want the focus of your photograph to be.
Small Aperture (f stop) = Large Depth of Field
The image below was shot at f/32
Large Aperture (f stop) = Small Depth of Field
The image below was shot at f/5
Get creative with the assignment. Look at the images below and see how our perception of what the photograph is about is changed by the depth of field.
How would Eli Reed’s portrait of Tyrese Gibson change if Eli Reed had used a smaller aperture and had the whole image in focus? Or how would the photograph be different if the child in the background been in focus and Tyrese Gibson been out of focus?
Here is another Eli Reed photograph which uses depth of field well.
Here is another example, this time in daylight. Notice how even a subtle use of depth of field enhances what the photograph is about.
