Sony has been making all the

famously with coverage of several
World Cup 2014 matches. Their
production isn't all about the cameras
of course, and Sony would be among
the first to admit that the quad-4K
solution which pushes four streams of
HD-SDI around live production circuits
is a stop-gap until

reality, observational documentaries
and children's, as well as drama, are
being acquired on cameras like the
Alexa, BMD Cinema Camera, Panasonic

UHD & Beyond
The big news from ARRI is that it
upgraded the Amira to provide incamera recording of UHD in ProRes.
Alexa shooters can also now upsample the image from the 3.2K sensor
to as near as dammit to 4K.
ARRI's view in any case has long
been that resolution is just a number
among other factors that are equally,
if not more, important. The mix of
light sensitivity and colour balance
along with pixel count delivers the best
looking picture, they argue, and many
film and TV cinematographers agree.
It has, though, unleashed a

Filmmakers like Christopher
Nolan and JJ Abrams are
championing the format. Nolan shot an
hour of Interstellar on IMAX cameras
and the film had an IMAX release
while IMAX 70mm cameras have been
used on a single action sequence on
Star Wars: The Force Awakens. IMAX
cameras have also been used on
Mission: Impossible - Ghost Protocol
and The Dark Knight Rises. Earlier this

was the first to be shot with the IMAX
dual 65mm 4K 3D camera.
The EOS C100 Mark II is the first of
Canon's Cinema EOS range to feature
integrated Wi-Fi connectivity for the
sharing of footage and remote control
of the camera. Also released is a free
firmware update for the C500 adding
support for the ITU-R BT.2020 colour
space, for greater colour accuracy
through to the grade.

Smart Light-field
Implementation
On a side note, the first
implementation of light-field data
technology for moving pictures is
now available as a plug-in for Avid.
Fraunhofer's light-field technology
uses 16 smartphone camera modules
to produce a single recording
containing several different views,
which are then used in postproduction to recover the creative
opportunities that were not explored
on set.
Changes to shadowing, angle and
more complex effects can be realised
in post based on just a single shot. A
GUI allows the view to be horizontally
or vertically manipulated and a
virtual camera can be moved from
the front to the background, so
virtual camera rides can be easily
created with real film shots.
Fraunhofer is running a pilot
programme with select Avid editors
to integrate this functionality into
existing post software.
