CoursesDigital Photography Made Simple — Lesson 1 — Page 4Depth of FieldA large aperture setting — lower f-stop setting — creates a shallow depth of field. With a shallow depth of field, objects in front of and behind the image subject appear somewhat out of focus. This may be desirable for a portrait or close-up of a flower, so that the crisp subject "pops" from the softer background. A smaller aperture setting — higher f-stop setting — has a greater depth of field, in which all objects appear in focus, regardless of their position relative to the subject. Demo 1-13 shows how photos look with both large and small aperture settings. Demo 1-13: A shallow depth of field brings focus to a specific subject, such as a flower, while softening the background of trees. A greater depth of field focuses equally on all subjects. White BalanceWhite balance compensates for different types of lighting that can create a dominant hue of color that needs to be corrected to produce more natural results. Some types of light for which an available white balance preset may compensate include:
Demo 1-14: White balance settings. In addition to the presets, a higher-end camera might be capable of taking a manual sample to measure the light's temperature in areas where you're taking photos. Burst ModeMore and more digital cameras have some type of burst, multiburst, or continuous mode for taking a series of photos in quick succession. Select and use a camera with a burst mode if you want to shoot a lot of action, such as someone throwing a frisbee as shown in Demo 1-15. The capability or performance may vary by:
Demo 1-15: The burst mode allows you to take a continuous series of photos in quick succession. Now it's time to find out about file formats, such as JPEG, TIFF, and RAW. That's coming up in the next section. |
