[QUOTE="blackstar, post: 738990, member: 47518"] Thanks, Cindy. Yes, I have studied both "dynamic range" and "HDR" and I do agree with you that cameras' image sensor is far inferior from normal human eyes. Yet the details of how cameras visualize and perceive a scene as well as how they proceed and set all parameters to take a shot are still beyond my comprehension. As for how to reset EV=0 after taking the shot by photo editor, I doubt it can be done by straightforwardly inversing the EV#. I did it again with EV set to 0 and all came out like (almost) ideal exposure. Here is one of them (A mode with best DOF): [ATTACH=CONFIG]341951._xfImport[/ATTACH] And look at the blue sky :) [/QUOTE]
