Can iPad Pros HDR screen show the fully dynamic range of a RAW photo file from an SLR camera ?

[whitedragon101]

The iPad Pro keynote said the screen did HDR. Now photographers know a RAW file from an SLR camera requires processing to cut off a big chunk of dynamic range to make a jpg. And you can only view a certain chunk of it at one time.

Can the iPad Pro show the full dynamic range of a RAW photo all at the same time?

I’m not an expert on this, but i think it’s more complex than a yes or no answer. I think colour gamut is more relevant than HDR.

There is no standard for raw files and so they vary considerably. Adobe DNG is the most common with cross manufacturer support.

Then there’s how the raw file is displayed. It can’t be displayed without being processed (i think the bayer filter is still impacting the raw data, so pixels are either red green or blue and not interpolated yet) This conversion will apply a colour space to the image - ie set the ranges of colours which are possible. sRGB is most common but iOS supports DCI-P3 which is a wider space. The iPad screen supports this too.

It’s only when the image is saved as a jpeg is data lost.
