DSLR Camera Review







DSLR Camera review terms and definitions.

Learn and review what all the terms and lingo thrown around about DSLR cameras really mean.

Autofocus (AF)- The DSLR camera lens focuses automatically, and usually when the shutter release is half-pressed. One easy way to compare DSLR cameras is to count their autofocus points. Typically the more points, the better the autofocus system.

Burst Mode - This is sometimes referred to as rapid-fire shots or continuous shooting. Burst mode captures multiple digital pictures in rapid succession with just a single click of the exposure button. It is usually measured in frames or images per second.

Color Balance - Is the accuracy in which the colors that are captured in the image match the original scenery.

Dynamic Range - How accurate the image taking by the DSLR is in gray level or color. Reviews show that more bits of dynamic range will result in higher quality and finer gradations being preserved.

Exposure Bracketing - The ability to take multiple versions of a picture using your DSLR camera at different settings. This thereby increases your chance of capturing a properly exposed image under more challenging lighting conditions.

Face Detection - Face Detection technology uses special algorithms embedded in the DSLR camera that can detect typical face patterns in a picture and then automatically adjust the focus and exposure to improve the picture quality.

Image Resolution - This measures the clarity and sharpness of the digital image. The more pixels the DSLR camera has, the greater the pictures clarity and detail will be.

ISO - The higher the ISO number supported or allowed, the "faster" the film. Higher ISO means that less light is required to take a photo.

Image Stabilization - Reviews will show that DSLR cameras may be difficult to hold steady for a long period of time. Image stabilization will help to minimize picture movement by digitally stabilizing the camera and picture.

Live View - This capability, which is fairly new to DSLR cameras, allows you to see and review the image live before you take the shot. The live-view feature makes it significantly easier to shoot at high and low angles, shoot close-ups, and it also allows for easier manual focusing, composing, as well as depth-of-field checking in low light.

MegaPixels - Digital SLR camera are commonly rated and reviewed by Megapixels. It is determined by multiplying the number of pixels wide by the number of pixels high. The greater number of pixels the camera has, the greater the image quality.

Noise - Noise is defined as pixels that appear in your digital image that were not “interpreted” correctly. Reviews will show that noise will appears as random groups of green, red, or blue pixels. When it occurs, it usually occurs when the user shoots a long exposure, say over 1/2-second, or when a user uses a higher ISO setting, typically higher than 400.

Optical Zoom - The Digital SLR camera lens does the work for you by enlarging or the field of view. For example, a 16:1 zoom can magnify the object up to 16x . Optical zoom is a better feature than digital zoom because the image quality does not degrade, which can happen using digital zoom.

Scene Selection Modes - New DSLR cameras now come with this feature that allows the user to selects the best preprogrammed scene that will meet their shooting conditions. The DSLR camera will automatically change many settings to set up everything for shooting just about any scene or subject that you are likely to encounter, such as landscapes, portraits, sunsets, action, fireworks, and even underwater!

White Balance - This is a DSLR camera feature that will automatically review, assess and compensates for various color conditions in any given lighting environment. The camera will help to ensure the most true-to-life color quality possible.
