Is more dynamic range always better?


Suppose there are two cameras in front of you. Both output 14-bit 24Mpx RAW files. Camera 1 has a dynamic range of 12 ev and camera 2 has a dynamic range of 15 ev. Camera 2 is clearly the winner because it gives more range to recover from shadows and highlights and, in particular, background skies are less often blown up when I take a picture. However, both cameras output 14-bit RAW files. Therefore, technically, the 15 ev camera does not output "more information" than the 12 ev one in its RAW files. 1. Is there a context (studio maybe?) where a smaller dynamic range is better than a wider one? 2. Supposing that we live in a world where we can make cameras with the dynamic range that we want, how much dynamic range is too much dynamic range? 3. Is it possible to have so much information put in the shadows and the highlights that we have only few information left for the +/-3 stops around a given exposure? 4. Would such a picture look like a picture where some photoshop slider was put way to far? 5. In 2040, will we have 20 ev dynamic range cameras? via /r/photography https://ift.tt/3dNxUBW
