Photo 1 Depth-of-Field Step by Step

Depth-of-field is the range in which objects in your photograph are in focus. The fundamental way, in which a photographer controls light, is by changing the aperture and the shutter speed. These changes affect the way that your camera sees the subject. As an artist, you must take control of the camera and manipulate it to get the desired result. Small apertures will cause a deeper depth thus providing detail in the whole photograph. Large apertures will give you shallow depth-of-field; this will draw attention to the foreground.

Photo #1 (Max Depth of Field) Step 1: Focus your camera on something not more than 5 feet away (like the handle bar in this example). DOF is exaggerated the closer you are to your subject so it is very important that you focus your camera on a subject that is NOT more than 5 feet away! Make sure that you can see some background. (like the other bikes and the building in this example.) Step 2: Set your shutter speed to 1/60th of a second. This is the slowest shutter speed you can use and still hold your camera by hand. This slow shutter speed will provide you with the smallest aperture possible and thus the MAX depth. Step 3: Take a light reading. (Exactly how to do this depends on the camera you are using so be carful to make sure you understand how to take accurate light readings with the camera you have.) Fine-tune the aperture to get your light meter â&#x20AC;&#x153;happyâ&#x20AC;? and take the picture! Step 4: Make sure that you accurately log the subject, focus distance, aperture and shutter speed used. It should look something like the example below. ____________________________________________________________________ Subject:

Step 8: Repeat these steps to make as many sets of photographs as you can. 10 good sets will get you all 50 points. 8 good sets will get you 45 of 50 points. 3 good sets will get you 40 of 50 points. 1 good set will get you 35 of 50 points. You have a good set if and only if: Each negative in set has a subject that is less than 5 feet away and is clearly in focus. Each photo in set is the same in terms of subject matter and total exposure. There is a dramatic rage of depth of field clearly visible.

Remember: Load and unload your camera carefully Log every shot... even if you make a mistake. NEVER shoot into the sun. ALWAYS focus on something less than 5 feet away! Creativity will not be graded but it never hurts!
