Medium format, meet HDR. HDR meet medium format.

HDR NOTES OF INTEREST
1. Shoots a bracket, merges to HDR and merges IN CAMERA
2. Single shot Dynamic Range Expansion to handle highlights and Shadows

Pentax has finally released the Pentax 645D which is a 40mp medium format camera. Rather than list the massive breakdown of the camera specs I’ll simply link the press release below.

The in-camera HDR capture/merge function is of course of particular interest to me, but I’ve yet to find what controls one has (for example: amount of bracketing/steps).

Other noteworthy features listed (but no juicy specifics) are:

INTERVAL SHOOTING

EXPOSURE BRACKETING

EXTENDED BRACKETING

I’ll post more if I find specifics, but don’t get too excited.  The release is initially limited to sales in Japan only.
