8. The DSLR If you really want to dredge into the specifics, you can do that at Wikipedia. Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light

ISO (and Image Noise) Increasing the ISO setting lets you take clear photos in dim light without having to use a flash, but it also degrades the image quality. Dust Control Dust that lands on an SLR sensor appears as small black spots in every photo you take. Dust controls systems attempt to prevent and eliminate this.

Regardless of the type, stabilization helps to eliminate blur in your photos caused by camera shake. Live View With a live view system, you can compose photos using the LCD screen on the back of the camera in addition to the viewfinder. Dynamic Range Your eyes have exceptional dynamic range and can see details in a scene even when there's extreme contrast. Unfortunately, an SLR doesn't work quite as well as your eyes.

Autofocus Autofocus systems can include anywhere from 3 to 51 individual focus points. More important that the number of points is the accuracy of the system. Frames Per Second The amount of photos you can capture in your cameras continuous mode. Ranges from 2.5 fps – 11fps. In order to maximize your fps rate you must be shooting at a fast enough shutter speed.

Aspect Ratio Wonder why your digital prints never turn out exactly like the image on your computer monitor? The culprit is aspect ratio. HD Video Video is become more common on DSLRs and allow for you to record professional quality videos. Be weary of sound when you do not have an external microphone Points of Focus Allows you to choose where you want to focus. Most cameras have anywhere from 3 – 51 focus points. It is alternative to manual focusing

49. Lenses Lens - One or more pieces of optical glass or similar material designed to collect and focus rays of light to form a sharp image on the film, paper, or projection screen. Lens Shade - A collar or hood at the front of a lens that keeps unwanted light from striking the lens and causing image flare. May be attached or detachable, and should be sized to the particular lens to avoid vignetting. Aperture - Lens opening. The opening in a camera lens through which light passes to expose the film. The size of aperture is either fixed or adjustable. Aperture size is usually calibrated in f-numbers-the larger the number, the smaller the lens opening.
50. Key Terms/Features If you really want to dredge into the specifics, you can do that at Wikipedia. Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light F Stop Numbers Numbers on the outside of the lens corresponding to the aperture opening. The larger the number (e.g., F/22), the smaller the opening of the lens; the smaller the number (e.g., F/2.8) the larger the opening of the lens. The f-number is equal to the focal length divided by the aperture diameter. Fixed Focal Length A camera with a non-removable, non-zoom lens. The lens focal length can't, therefore, be changed. DispersionLight rays of different wavelengths deviate different amounts through a lens causing a rainbow effect around points and edges.

Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light Flare Reflected light from lens elements, metal, etc. Appears as a non-uniform haze or bright spots on the film. Usually occurs when bright light (sun) enters the lens. Focal Length The distance between the back lens element and the focal plane. In 35mm format, lenses with a focal length of approximately 50mm are called normal (standard), lenses 35mm and shorter are called wide-angle, and lenses with a focal length of more than approximately 70mm are called telephoto lenses. Infinity In relation to camera focus: the horizon. Aspherical Not a continuous curve. Refers to elements in lenses which have been designed to compensate for distortion by having different curves on individual elements. Allows for a more compact lens.
52. Canon Terms If you really want to dredge into the specifics, you can do that at Wikipedia. Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light Ultra Low Dispersion A type of glass used by Canon to make lens elements. "UD" glass corrects for chromatic aberration. Image Stabilization Compensates for camera shake allowing slower shutter speeds. USM Canon designation for "Ultrasonic Motor". Canon's fastest autofocus lens technology EF Lens Designation for Canon EOS system autofocus lenses.
53. Nikon Terms If you really want to dredge into the specifics, you can do that at Wikipedia. Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light ED (Extra Low Dispersion) Glass A glass developed and trademarked by Nikon Corporation, used in telephoto lenses to obtain optimum correction to help prevent chromatic aberration. These lenses are resistant to temperature changes, preventing focus shift problems in lenses that use calcium fluorite crystal elements. Vibration Reduction Compensates for camera shake allowing slower shutter speeds. AF-S The auto-focusing mechanism is built in the lens making them compatible for Nikon’s entry level cameras and allowing to focus faster on other Nikon bodies*
60. 7Steps to Choosing a Lens Decide on your budget Determine the focal length you'll need Decide if you want a prime or zoom lens Select a maximum aperture Choose between first or third party lenses Evaluate any extra features Read reviews and narrow your options
62. Flashes Flash - Artificial light source. Usually camera mounted but also larger studio models called strobes. TTL - Refers to flash or exposure metering which is read "through the lens" at the film plane. Hot shoe: this is the most common and obvious way to connect an external flash unit to the camera. Hot shoes have electronic connectors that can relay information from the SLR to the flash, but only when the flash brand matches the camera.

Light passes through the lens and strikes a mirror (green) The mirror reflects the light up to a focusing screen Light passes through the focusing screen and enters a block of glass called a pentaprism (orange) The pentaprism reflects the image so that you can see it in the viewfinder When you take a photo, the mirror flips up and a shutter (blue) opens that exposes the digital sensor (red) to light Bounce When a flash has bounce, it simply means that you can angle the flash head so that it doesn't point straight ahead all the time. Swivel Swivel is a lot like bounce: it means that the top of the flash can be rotated to point to the left or right. While any flash with swivel also has bounce, the reverse is not always true: there are some flash units that have bounce but NOT swivel. Power The light output of different external flash units is described using the Guide Number.
65. Key Terms/Features Dedicated Flash A fully automatic flash that works only with specific cameras. Dedicated flash units automatically set the proper flash sync speed and lens aperture, and electronic sensors within the camera automatically control exposure by regulating the amount of light from the flash Wireless Flash The ability to wirelessly set off your flash when not attached to your hot shoe. *Nikons use their Creative Lighting System **Canons require pocket wizards or other wireless remotes.
66. Key Terms/Features Slow Sync Flash A function found on many cameras that tells your camera to shoot with both a longer shutter speed as well as firing the flash. Rear Curtain Sync Tells your camera to fire the flash at the end of the exposure. Front Curtain Sync Tells your camera to fire the flash at the start of the exposure. Red-Eye Reduction Used more for the pop-up flash, but it sets off multiple flashes to allow for the iris of the eye to close to prevent the red-eye effect
