Re: Hot pixels

[David Oswald]

My suspicion is that it is probably not real good for the CCD chip to 
run this "program" too often.  Don't think of it as wiping the 
black-board.  Think of it as sanding and retexturing the surface of the 
blackboard.  You only have so many times you can do that sort of thing 
before the surface wears thin. :)  At best, this is a rough comparison. 
 But it is entirely possible that the energy used to wake up bad CCD 
pixels is enough to do some degree of wear on all pixels.

If that is the case, Pentax may have not made it a built-in feature out 
of fear that people might go nuts and do it every few days until the CCD 
chip is toast.

This is all speculation.  Maybe an engineer could chime in. ;)

pity Pentax didn't do this
