This video illustrates the biggest flaw of the bmcc perfectly

Just a few own experiences. 13 stops do not dramatically change the way you expose compared to the 11 stops possible with contemporary DSLRs through curves. You still can't capture, say, the clouds in the sky and the black cat in the deep shadow. In this instance, you'd had to decide for the sky (ETTR with zebra), because clipped skies look really awful.


So if there is any chance to bounce the shadows (thus reducing DR deliberately during recording), you should do that.


Different with 'practical lights'. Let a light bulb clip.



This was ISO 800, as seen by automatic ACR. The lamps zebra-ed with 100%. The magenta cast was because I didn't yet have the IR-cut filter.




As you can see, the outlines of the lamps can still be recovered, no terrible blooming, no black dots or the like. Just that it's not possible to extract a natural 3200°K feeling with the cast (caused by IR pollution).

Here is an example of a wide dynamic range scene I shot. The scene was exposed for around ISO 2000  - shot at 800 and pushed to 2000 in Resolve. 


It was filmed with no clipping at all - 100% zebras.


NR has been applied in post. 






How it looked before grading:




It is an example of ETTL.




Here is an example of extreme ETTR 2 and 1/2 stops with zero clipping. 






For your consideration -  here is the exact same shot, but filmed in Prores mode at 800 - also stopped down 2 + 1/2 stops. 

This gives you an idea of how well ProRes stands up to such extreme ETTR also. Although it is not worth it, as you may as well just set the ProRes to 200 and bring it down 1/2 a stop in post - Rather than film at 800 and reduce by 2 and 1/2 stops. But It at least gives you an idea of how far you can push ProRes.






All of these were done on the BMCC EF mount - not pocket camera.
