* This function is only available with THETA X(firmware version 2.60 or later).

Withthe plug-in “HDR-DNG,” images are recorded in 16-bit depth, which containsgreater information than the JPEG (8-bit depth) format in the existing HDRrendering mode of THETA X. This allows for shooting of 360-degree images with overexposure/underexposuresuppressed and with noise in dark areas reduced.

Moreover,shot images can be saved in DNG file format, making it possible to develop360-degree images with the white balance and exposure adjusted usingdevelopment software such as Adobe Lightroom.

HDR-DNGis pre-installed in THETA X (firmware version 2.61.0 and later), so you can usethis function simply by updating the firmware.

Howto start “HDR-DNG” and how to shoot with “HDR-DNG” are described below. Referto them when using “HDR-DNG.”
