Shooting In High Dynamic Range (Hdr) - Sony PXW-Z90T Operating Manual

Shooting in high dynamic range
(HDR)
Reproduction of brightness over a wider
range than previously available is supported
by applying an HDR-compatible picture
profile. The camcorder supports Hybrid
Log-Gamma (HLG), with four selectable
gamma settings.
The [HLG] setting is equivalent to ITU-R
BT.2100. The [HLG1], [HLG2], and
[HLG3] settings enable images to be
reproduced with a wider dynamic range
without images that appear unnatural, as
can arise in existing camera image
reproduction.
Shooting using HDR-compatible
picture profile
An HDR setting is registered in [PP10] by
default for shooting in HDR.
[HLG], [HLG1], [HLG2], and [HLG3] can
also be used in [PP1] to [PP9].

b Notes
• XAVC format recording
When recording HDR video in XAVC format
on the camcorder, the color space, gamma, and
other metadata required for HDR playback and
display are stored in the video file.
On devices used for playback and display that
support the metadata, the video is displayed

automatically with the appropriate settings. On
devices that do not support the metadata,
manual configuration is required.
• AVCHD and MPEG HD format recording
AVCHD and MPEG HD format recordings do
not support HDR metadata. For appropriate
playback and display of HDR, manual
configuration is required.

Item Description
[HLG] Setting equivalent to ITU-R
BT.2100.
[HLG1] Setting that provides greater
noise suppression than [HLG2].
However, the dynamic range
that can be shot is narrower.
[HLG2] Setting with balance between
dynamic range and noise
suppression.
[HLG3] Setting that provides wider
dynamic range than [HLG2].
However, the noise level rises.
[HLG1], [HLG2], and [HLG3] all use the
same gamma curve characteristic. Only the
dynamic range and noise suppression
characteristics differ.
