Introduction to Digital Photography

Aperture - ansSize of the opening in a lens Shutter Speed - ansHow fast the shutter opens and closes ISO - ansHow sensitive the camera sensor is to light Depth of Field - ansTerm that refers to how much of the image is in focus High Dynamic Range (HDR) - ansSeveral photos of the same scene taken at different exposures Bokeh - ansThe blur or orbs created when lights or backgrounds are out of focus in an image Al Servo or Continuous Focus - ansthe autofocus system will continue focusing until you take the photo, so the subject is still sharp, even if they move. This camera setting is essential to understand for photographing moving objects Exposure - ansHow light or dark an image is and is controlled through aperture, shutter speed and ISO Histogram - ansIs a chart that depicts how many light and dark pixels are in an image. If the chart peaks towards the left, the image has a lot of dark hues. If the chart peaks to the right, the image has a lot of light hues. If those peaks are cut off at the edges, the image is underexposed (on the left edge) or overexposed (on the right edge) Long Exposure - ansIs an image that has been exposed for a long time, or uses a long shutter speed. This technique is useful for shooting still objects in low light, or rendering moving objects into an artistic blur Hot Shoe - ansIs the slot at the top of a camera for adding accessories, like a speed light or flash Manual Mode - ansYou choose the aperture, shutter speed and ISO, and those choices affect how light or dark the image is Noise - ansIs simply little flecks in an image, also sometimes called grain. Images taken at high ISOs have a lot of noise, so it's best to use the lowest ISO you can for the amount of light in the scene Rule of Thirds - ansThis compositional rule suggests imagining the image has been divided into three parts both horizontally and vertically. Often the most interesting compositions result in placing the subject on one of the intersections of those imaginary lines, instead of in the center of the photo. Shutter Release - ansThat's the button you press to take the picture
