E2. Gamma Categories
The PXW-FS7 Gammas are split in to 3 categories: STD/
HG/S-Log (MENU: Paint – Gamma – Gamma Category).  
E 2 .1  STD
Standard Gamma. The gamma curves available under 
this category are all variations on standard television 
gamma. These curves will all provide realistic and true to 
life contrast when viewed on a conventional TV or monitor. 
However to comply with current television standards these 
curves have a limited dynamic range....

STD-R709 Gamma Curve
E2.2 HG 
Hypergamma. These advanced gamma curves are 
designed to capture a wider dynamic range than the 
standard gammas with only a small reduction in on 
screen contrast (normally the higher the cameras capture 
dynamic range the lower the on screen contrast will be). 
This is achieved through careful addition of a gradual 
highlight roll off. The different curves offer different 
dynamic ranges and as a result should be exposed...

The capture range and optimum exposure levels are 
indicated in the full name of the hypergamma curve,  
for example:
HG4609G40 = HG – 460 – 9 – G40, which indicates 
HG(Hypergamma), with an over exposure range 460% 
greater than standard TV gamma. Recording to 109% 
(the other option being a “0” which indicates recording to 
100%). G40 being the  optimum exposure for a 18% middle 
grey card of 40%.
In practice a Hypergamma with a lower “G” middle grey...

Hypergamma 1 Hypergamma 2
Hypergamma 3Hypergamma 4
I find that Hypergamma 4 works very well for brighter 
outdoor scenes while Hypergamma 3 works well for 
indoor scenes. Hypergammas 7 and 8 are also very good 
for challenging lighting situations.
E2.3 User
It is possible for advanced users to upload their own 
gamma curves to the camera.

E2.4 S-Log2
You can use the S-log2 gamma curve in Custom Mode  
to capture an extremely large scene brightness range  
(14 stops or 1300%). This will result in a very flat on screen 
image. The PXW-FS7 is primarily designed to use S-Log 
recording in the Cine EI mode but the option is also 
offered in Custom Mode to help deal with particularly 
difficult lighting situations.  
S-Log3: Like S-Log2 you can use the S-log3 gamma curve 
in Custom Mode to...

E3. Custom Mode Matrix Settings (Color adjustment)
The camera’s color reproduction can be adjusted by 
making changes to the matrix settings. 
(MENU: Paint – Matrix)
There are 5 preset matrix settings designed to give easy 
access to a number of different color responses.
E 3 .1  Recommended settings
The standard color matrix works well for general purpose 
acquisition. If you are shooting under florescent lights or 
LED lights and you notice a green cast...

Combining a Hypergamma with the Cinema Matrix produces images 
that are more film-like than the standard settings. In this example 
Hypergamma HG3 is combined with the Cinema gamma.
E3.2 PXW-FS7 II and the Rec2020 Matrix
The FS7 includes an additional matrix that complies with 
the new Rec2020 color standard. This standard allows for 
the capture and display of a wider range of colors than 
possible with Rec-709. Many recent TV’s have the ability  
to...

E3.3 The High Saturation matrix can be used to provide 
vibrant colors for music or pop videos, but it must be 
noted that in some cases strong colors in the scene you 
are shooting will reach the maximum recording intensity 
more quickly.

F55 709 Like Matrix F55 709 Like Matrix
The F55 709 Like matrix is designed to mimic the color 
response of the Sony F55 camera. It provides vibrant 
colors. This matrix can be used when trying to match  
the pictures from an FS7 to a PMW-F55 that is shooting 
Rec-709.
