With modern day digital cameras, and even film (celluloid) for that matter, the RAW image already contains the extended dynamic range. Colorists can see it, it’s just that the end user doesn’t with current SDR mastering, e.g. from almost a year ago -

Then, afterwards, when flipping back to traditional non-HDR mode, it’s amazing how much RAW imagery (be it from the Alexa, RED, Sony--whatever high end camera be your acquisition device) is clipped at 100 nits.

The problem is that with high or extended (as Dolby actually prefers calling it) dynamic range is that it is even less forgiving than shooting in 4K which, in terms of the cost issue which you bring up, could potentially push make-up, set design, etc. to *up their game*. Additionally, I would say that in order to get ‘the full effect’ or the
best effect out of Dolby Vision or any high dynamic range solution will be to light the scene in a way that would make the most out of an HDR finish…which could contribute additional cost. And the best way to check the lighting of a scene would be with the use of an HDR on-set monitor, of which, as of now, there is no practical product available for D.P.’s.
The producer can always have a colorist do an HDR pass on a good dynamic range element from a high end modern day digital camera or even film and produce something better than SDR mastering if the Director and colorist work collaboratively at it but, to get the full effect out of any HDR finish I think it would be optimal to have that finish in mind from the get-go and structure the production accordingly…which could incur additional cost. This is all new territory and the
learning curve for everyone has just begun.
