photography

For a recent project, I had to make some rough LUX measurements (LUX is a more international standard for light measurement than candlepower, which is traditionally used in the U.S.) of an environment to help determine what kind of video cameras to use. Problem was, all I had was a spot meter—an incident light meter for film/digital photography, that would give me a reading of, say "1/15 second exposure at f/5.6 and ISO 100."

After looking around online a while, I found a simple method to get a rough estimate of the LUX measurement from these photography measurements.

Ever wonder why your pictures of little items like statues, money, a speaker set, a glass of water, or pretty much anything else in the world that doesn't move often look so washed out and flat? I'm betting that the reason is that you are setting your camera to 'nuke' mode (i.e. blast everything with light from the flash).

Well, I have a quick, and most likely free (if you own a tripod) solution to this problem. And it's pretty darn easy to implement. Here's how you do it:
