dynamic range


#1
hi,

recently i came across a term called dynamic range.

is it related to cmos sensor size and pixel size?

how do i know whether the camera have better dynamic range?

Dynamic range, in a nutshell, is how able the sensor is in capturing the wide expense of tones in the scene (or the brightest to darkest point). Even today, most digital cameras do not match the DR of the eye.

It is loosely linked to sensor size, yes, but this is changing. A full-frame camera used to be the key to getting better DR, but the recent Nikon D7K and Pentax K-5 are pushing this notion away.

Nikon camera generally have larget cropped sensor size.
and if the "mega-pixel" is small, meaning higher dynamic range?
==> meaning calculated by total number of pixeld divided by sensor area?

if not, how do we normally compare dynamic range of 2 different camera?

thanks

Actually, it's not that Nikon cropped frame cameras have larger sensors than other brands, it's Canon that has a smaller sensor than other brands. All brands except Canon use DX (1.5x crop) sensors for their crop frame cameras, only Canon use APS-C (1.6x crop). However, Canon also has a 1.3x crop (APS-H). If you want to compare the dynamic range of cameras, go to DXOMark's website, they do sensor tests.

Dynamic range is not really linked to megapixel count. It's an aspect of sensor technology. Best way to compare is with detailed shot by shot tests to see where the shadow and highlight recovery is, then use some math. Easiest way is to look on sites like DXOMark, or read the reviews on DPReview.

Actually DX is also APS-C. All the 1.5x crop frame is all APS-C. just that Canon's implementation is 1.6x.
