<p>[QUOTE=&quot;jtlee321, post: 2540804, member: 73983&quot;]You are correct.&nbsp; A large percentage of the bit depth is assigned to the highlights compared to the shadows.&nbsp; It&#039;s certainly not a linear distribution.&nbsp; The human eye is more sensitive to picking up differences in the highlights than in the shadow&#039;s which is why engineers designed the camera sensor the same way.&nbsp; More than 50% of the available bit depth is assigned to recording the first 33% of the information in the highlights.&nbsp; As you get down to the shadow information there are far fewer bits available to record that information.&nbsp; This explains why it&#039;s easier bring exposure down in post processing without a big degradation in image quality.&nbsp; On the hand when you try to bring up the exposure in an under exposed image, you start to introduce a lot of noise or color anomalies in the shadows.[/QUOTE]</p><p><br /></p>
