IMAGE SIZES - What are Megapixels and
Resolution?
In order to print high quality photos you need to save images in a high
quality format. Balancing this is the
need to not fill up your file storage too quickly, and that when emailing files
you don’t want them too big.
To manage files you need to understand how to make your camera settings
high enough to take high quality photos and how to resize them afterwards for
other purposes.
Resolution
Resolution refers to the size of the image that your camera will
produce. This is normally referred to as megapixels. Megapixels represent the
number of pixels for an image. For
example: A 1600 by 1200 pixel image is 1600
times 1200 = 1.92 million pixels or 1.92 Megapixels. This would commonly be
rounded up and referred to as a 2 megapixels.
