What’s the difference between pixels and dots? A . For a digital sensor, a pixel is a single light-sensitive address, so in this context pixels and dots can be considered synonymous. For output devices such as LCD monitors and computer screens, however, a pixel is defined as a triad comprising a red, green, and blue dot. So a 921,000-dot LCD screen is said to have 307,000 pixels. And yes, the terms get mixed up a lot. Do you have Tech Support Question? Post it on our Facebook Page.

Then upload your best shots to our Flickr page. See the whole gallery here TECH SUPPORT Pixel Protocols Q. What happens to all the other pixels when I shoot in medium JPEG or small JPEG? And what is the sensor doing differently between fine and normal quality? A. The camera uses information from all the pixels to generate JPEGs. In the case of the small and medium files, the processor sizes down the file in much the same way image editors downsize pictures, resulting in a lower pixel count than full resolution. JPEGs are also compressed files, and the quality settings indicate the amount of compression: a normal-quality JPEG is compressed more than a fine-quality JPEG, and thus gives you a somewhat smaller file size even if the two JPEGs have the same pixel resolution. In pictures without a lot of fine detail, you may not notice the difference, particularly at low print or screen magnifications, but in very intricate shots, and/or big blowups, the higher compression can show up in artifacts, notably jagged edges in details. For most applications, we recommend going with the highest pixel count and the best quality—you can always size the image down in any image editor later.
