Whether you have a Digital SLR and want to learn how to better use it, or if you are interested in buying a Digital SLR; Photo School is an indispensable resource that you can take with you on your iPad.* Focus Points *When your subject is off-center (and it should be), you must force the camera to focus off-center, there are three methods to get the proper focus in the camera.* Lens Aperture *Learn what the lens aperture is and what it does and how to use it to control depth of field.* Magnification (Cropping) Factor in Cameras *If you purchase a camera that does not have a full-size sensor, then it is much more difficult to get a wide-angle effect out of your lens. This video explains why.* Camera Focus Modes *DSLRs have three focus modes; two of which are designed for moving objects. How to choose the right mode for the situation.*White Balance *Light comes in a variety of colors; natural light from the sun is very different than light cast from street lights or fluorescent lights inside a building. Learn what features are available to help you combat color shift before you take the picture.* Multi- and High-Speed Frame Rates *Motion photography is an obvious reason to use a high-speed shooting mode, but if you need to blend several images (like HDR), then it is best to take those pictures in quick succession to limit variation.* Exposure Lock *Exposure Lock allows you to quickly set the camera exposure and take several pictures with the same settings without going to manual mode.* Camera Metering Modes *By default, cameras use every part of the sensor to determine image brightness, but sometimes you need to override it to help get the right exposure when the background is bright. Learn the four different metering methods available in your camera.* Exposure Compensation *Sometimes metering isn't enough to get the right exposure. Use the Exposure Compensation setting on your camera to change the brightness of your image at the moment you snap the picture.
