The Ultimate Exposure Computer

[johnastovall]

Looks like a very handy thing to carry for shooting without a meter.

"Imagine an exposure computer so advanced that it uses your eyes as a sensor. The processing unit is as powerful as your brain. The computer is accurate over a light range from reflected starlight through the light produced in a hydrogen fusion reaction. This computer weighs nothing and operates without batteries. It comes with instructions to allow you to implant the capabilities of the computer directly into your own memory so you can accurately judge a correct exposure by simply looking at the type of light that the subject is in. You are using this computer right now!
Everything I've said above is true. However, I'm sure you've noticed that the only thing before your eyes is a World Wide Web page. An entire photographic industry has been built by convincing consumers that the subject of photographic exposure is so arcane, difficult and impossible to understand, that it is best left up to technology. This, of course, allows companies to sell billions of dollars worth of equipment to figure it all out for you.
The fact is that the concept of photographic exposure is extremely simple. It can be mastered by anyone who can multiply or divide by two. Everything you need to know is contained on these few Web pages."
