Resolution in Photography


Resolution is simply the measurement of a pixel plane and is used for measuring monitors, digital photo sensors, and just about anything you’d put on a monitor or photo sensor such as web pages, photographs, and windows. Resolution is measured in pixels and megapixels. The amount of pixels that a camera catches in a single photograph is known and quantified as the resolution. For example, a camera that can catch 2950 x 1862 pixels on a camera, which would translate into 5.4 mega-pixels.

From there you then know that this 5.4 mega-pixel camera has a higher or better resolution than a 2.0 mega-pixel camera.

Does More Pixels (Higher Resolution) Mean Better Quality?

To a certain degree, the resolution can be a big factor in determining quality, but it can only do so much. A camera’s optical system is only as strong as it’s weakest link.

The main reason why you want a higher resolution is that with a higher resolution you have more captured pixels to work with when it comes to editing or cropping. You can also make larger prints with more pixels. With more pixels you can maintain a good, sharp image even if you enlarge it or crop it. Just keep in mind that just because it will blow up doesn’t mean its good quality. Every picture degrades in quality the more it is blown up, but with a higher resolution picture you can blow it up more before it reaches that point of visible degradation.

In short, when it comes to image resolution, all it telling you is how many pixels will fit inside each inch of paper when it’s edited, cropped, and printed out.
