What is a “Stop” of Light?
The concept of a “stop” of light is probably the most important concepts in photography, yet it’s widely misunderstood. In this article, we want to take you back to the basics to help visualize a stop of light and changes in exposure.
A stop of light is not a quantifiable unit of light entering the camera but rather a relative one. Therefore, increasing by one stop doubles the amount of light let into the camera while decreasing by one stop cuts the amount of light in half. [click to continue…]

I recently received a question from a reader about a slow import process from his memory cards into Adobe Lightroom. He was using a USB 2 card reader and wondered whether that could be the culprit. And, if so, would upgrading to a new iMac with USB 3.0 and a Thunderbolt fix the problem if he had a USB 3 or Thunderbolt card reader? (To my knowledge, there are no Thunderbolt CF or SD card readers shipping at the time of this article. There is a Thunderbolt SxS card reader for the pro video market; however, it is currently listed as discontinued.)
