Custom mode is good for creating a
baked in look in camera or for
workflows where the amount of post
production will be minimal. Do also
consider as an alternative using
CineEI mode and baking in a look by
using a LUT with (Video – Monitor
LUT – Main&Internal) set to ON. The
LC-709 TypeA Look creates a very
pleasing image.
Custom mode is selected in (System
– Base Setting – Shooting Mode –
Custom).
For most applications you will use
YPbPr. RGB would only be used
when recording with SStP 444 for
very high quality productions,
perhaps green screen work. (System
– Base Setting - Main Operation)
The Gamma curve effects the
contrast and dynamic range of the
recordings. When the gamma curve
selected in the camera does not
match the gamma curve of the
monitor the contrast will not be
normal (typically flat and washed out).
Most TV's and Monitors use a
gamma curve called REC-709 or
something very similar. The camera
has 5 different classes of gamma,
STD (standard) HG (Hypergamma),
User, Slog2 and Slog3. (Paint –
Gamma – Gamma Category).
Limited dynamic range but closest
match to most display devices.
Standard gamma gain is x4.0, so a
gamma with higher gain will be
brighter, lower gain darker.
STD5 R709 is the standard gamma
for HD television.
STD1 DVW – similar to older Sony
SD cameras.
STD6 x5.0 – 5x gain gamma, often
known as BBC gamma.
(Paint – Gamma – Gamma Select).
