1.2 Roundshot VR Drive Software Options (continued)
For 32-bit HDR images
„HDR" mode
In the "HDR mode" the camera is controlled by the VR Drive, enabling wider
bracketing for 32-bit HDRs.
Digital SLR cameras have a bracketing range limited to +/- 2 f-stops. For 32-bit HDR
photography this is insufficient. The VR Drive "HDR mode" overcomes this limitation
by controlling the camera software directly and allowing a virtually unlimited
bracketing range. It is an "all-in-one" solution - no additional devices are needed.
32-bit HDR images are used for 3D modeling (e.g. for realistic rendering of
construction data into a 3D environment) and for tone-mapping, allowing more
clarity and detail in bright and dark areas.
