Originally posted by Wheatfield For the dim witted, I would suggest you take a spot meter out and meter some scenes to see how much DR they encompass.
thank you for your input.
How about sending the same request to some of the key companies those make cameras. And see if they agree with you on importance of DR. And enlighten them how this area of sensor design needs no more improvement.
Edited to add:
For those who are interested in trivia.
This is from wiki
http://en.wikipedia.org/wiki/Dynamic_range
"A human can see objects in starlight (although colour differentiation is reduced at low light levels) or in bright sunlight, even though on a moonless night objects receive 1/1,000,000,000 of the illumination they would on a bright sunny day: that is a dynamic range of 90 dB."
If we think that one stop as multiple of two then
1,000,000,000 1
500,000,000 2
250,000,000 3
125,000,000 4
62,500,000 5
31,250,000 6
15,625,000 7
7,812,500 8

That is roughly 30 stops of DR is the range in which humans can discern things.
We humans are amazing thing.
