You don't buy a new car every month.

You don't frequently install or update anything in your car either (I cannot think of any other way in which it can break every few months). I am sick of the comparison between the car and desktop-computer industries.

Chief NSA Lawyer Hints That NSA May Be Tracking US Citizens 213

Posted by Unknown Lamer on Tuesday July 26, 2011 @04:33PM from the this-story-may-exist dept.

itwbennett writes "Responding to questions from the Senate Select Committee on Intelligence yesterday, Matthew Olsen, the NSA's general counsel, said that the NSA 'may', under 'certain circumstances' have the authority to track U.S. citizens by intercepting location data from cell phones, but it's 'very complicated.' 'There's no need to panic, or start shopping for aluminum-foil headwear,' says blogger Kevin Fogarty, but clearly the NSA has been thinking about it enough 'that the agency's chief lawyer was able to speak intelligently about it off the cuff while interviewing for a different job.'"

I wouldn't say that most cameras have a "real" dynamic range of 10 f-stops (the upper and lower stops are usualy just a result of interpolation and thus cannot really be used in practice). Only top-notch ones have 10-11 f-stops (a average DSLR camera does not have more than 6 usable stops).

However, your point is clear, definitely much more than one.

Video cameras, however, have just one f-stop to work with at any one time, and so must make compromises

Just to name one example, the Red One has a wonderful dynamic range of 11.3 stops. http://en.wikipedia.org/wiki/Red_Digital_Cinema_Camera_Company
