I asked a similar question in the past whether HDR photography can be
embedded in a digital camera. One of the readers questioned about the
purpose of this, since they can shoot RAW and do the work in PS or
PSP. Someone else indicated that for such processing inside a camera,
it will take a lot of work in their tiny processing software. So, I
assume that this has not been done.

However, I notice that some expensive DSLR cameras have over 50
focusing points, and perhaps they can also detect the variety of light
exposure within that 50 portion of the picture frame. I wonder if such
info can then be processed by averaging or other methods to capture a
broader range of light exposure in a photo. Is there a discussion
about what model and brand cameras that have such capability, or even
provide options on how to handle the different dynamic zones that
captured by the camera.... something like processing and combining/
blending different exposures to produce a single one (or more) that
will be stored as the final JPEG products after a shot in the digital
memory card. Some cameras has the AEB capability in which they take
3-5 shots with different exposure. Is there a camera that can also
produce 3 or 5 or more varieties, reflecting the blending and/or
combining of light exposures? Or is all expensive cameras such as
Nikon D300, D1, or Canon 1D, 5D are infact already have this feature?
I heard that Fuji Pro DSLR is known for wide dynamic range and
therefore used a lot for a wedding photography. Could someone comment
on this, whether the technology in this camera is about getting the
most varieties of light exposures in a photo?

The bottom question is whether HDR photography has been or can be
accomplished using expensive pro DSLR cameras, and therefore there is
no need to do it in a PS or PSP. Or, if this will be coming as new
feature in future DSLR cameras.

Thanks for info.
