Firma
Lytro ne propune o noua tehnologie inovatoare in domeniul video - camera Lytro Cinema care va oferi creativitate si flexibilitate nelimitata atat in timpul filmarii cat si pentru post productie (editare & efecte).
Cateva detalii:
- senzor 755 megapixeli - captura RAW;
- filmare slow-motion la 300fps;
- ajustare viteza cadre pe secunda (frame rate) si viteza de declansare (shutter) in PostProductie;
- camera tracking automat;
- gama dinamica (dynamic range) foarte mare 16EV;
- focalizare la alegere dupa filmare - inclusiv alegerea diafragmei in PostProductie pentru modificarea adancimii de camp (Depth of field);
- inregistrare in format 3D a adancimii de camp (Depth of field) - cu posibilitati de modificare ulterioara a imaginii in PostProductie prin efecte similare ChromaKey (vezi materialul video de mai jos).
Compozitie de tip ChromaKey dar fara folosirea unui background verde/albastru.
Inregistrare in format 3D pentru adancimea de camp (Depth of field) - oarecum similar cu modul in care lucreaza senzorul
Xbox Kinect
Light field camera tracking - transferarea informatiilor de la camera reala inclusiv miscare catre camera virtuala folosita pentru adaugarea de efecte care trebuie sincronizate.
Prezentarea oficiala
Pentru inceput camerele Lytro Cinema vor fi disponibile doar pentru inchiriere catre marile studiouri cinematografice - similar cu modul de lucru al firmei Panavision.
Puterea de calcul necesara pentru gestionarea si editarea unui asemenea nivel de date video va fi serioasa. Momentan pot sa ma gandesc la o singura varianta ca si configuratie - cerinte minime de sistem
Nvidia Quadro K6000 (24 GB memorie video).
Un exemplu de sistem poate fi cel de mai jos cu patru placi video Quadro K6000(11520 CUDA Cores), 2 procesoare Intel Xeon 2650v2 (2x 8 Cores @ 2.6 GHZ)
placa de baza SUPERMICRO MBD-X9DRG-QF-B, 128 GB RAM, 2TB stocare SSD, sursa 1500W Enermax.
Prima aplicatie care va suporta acest tip de material video va fi
Nuke urmand ca firma Lytro sa extinda suportul catre alte aplicatii cum ar fi Adobe After Effects, Autodesk Smoke, Fusion si altele.
Din pacate pana acum
aparatele foto Lytro nu s-au descurcat prea bine in vanzari si nici in teste. Multe dintre fotografiile realizate sunt destul de soft iar sensibilitatea la lumina slaba lasa de dorit in comparatie cu aparatele foto DSLR sau mirrorless. Au reusit sa ocupe o nisa in domeniul foto deoarece punctul de focalizare al acestor fotografii poate fi ales ulterior declansarii.
Firma Lytro a renuntat la sectorul consumer si nu mai produce aceste camere

Update 21-aprilie - NAB Show
Firma Litro a adus noua camera la expozitia tehnica NAB 2016 din Las Vegas. Dupa cum se vede camera are dimensiuni serioase avand racire activa. Vine cu propriul server care transfera datele catre Google Cloud la o viteza de 300GB/s.
Lentila din aceasta camera este 30-250mm cu diafragma constanta F/2. La demonstratia din Las Vegas au reusit sa obtina o diafragma de F/0.3 in post productie (efect adancime de camp DOF).
Rezolutia teoretica a materialului video este de 21MP, aceasta fiind cu mult peste standarul 4K.

Anuntul oficial:
Lytro Brings Revolutionary Light Field Technology to Film and TV Production with Lytro Cinema
- World’s First Light Field Solution for Cinema Allows
Breakthrough Creative Capabilities and Unparalleled Flexibility on Set
and in Post-Production
- First Short Produced with Academy Award Winners Robert
Stromberg, DGA and David Stump, ASC in Association with The Virtual
Reality Company (VRC) Will Premiere at NAB on April 19
Lytro unlocks a new level of creative freedom and flexibility for
filmmakers with the introduction of Lytro Cinema, the world’s first
Light Field solution for film and television. The breakthrough capture
system enables the complete virtualization of the live action camera --
transforming creative camera controls from fixed on set decisions to
computational post-production processes -- and allows for historically
impossible shots.
“We are in the early innings of a generational shift from a legacy 2D
video world to a 3D volumetric Light Field world,” said Jason
Rosenthal, CEO of Lytro. “Lytro Cinema represents an important step in
that evolution. We are excited to help usher in a new era of cinema
technology that allows for a broader creative palette than has ever
existed before.”
Designed for cutting edge visual effects (VFX), Lytro Cinema
represents a complete paradigm shift in the integration of live action
footage and computer generated (CG) visual effects. The rich dataset
captured by the system produces a Light Field master that can be
rendered in any format in post-production and enables a whole range of
creative possibilities that have never before existed.
“Lytro Cinema defies traditional physics of on-set capture allowing
filmmakers to capture shots that have been impossible up until now,”
said Jon Karafin, Head of Light Field Video at Lytro. “Because of the
rich data set and depth information, we’re able to virtualize creative
camera controls, meaning that decisions that have traditionally been
made on set, like focus position and depth of field, can now be made
computationally. We’re on the cutting edge of what’s possible in film
production.”
With Lytro Cinema, every frame of a live action scene becomes a 3D
model: every pixel has color and directional and depth properties
bringing the control and creative flexibility of computer generated VFX
to real world capture. The system opens up new creative avenues for the
integration of live action footage and visual effects with capabilities
like Light Field Camera Tracking and Lytro Depth Screen -- the ability
to accurately key green screens for every object and space in the scene
without the need for a green screen.
“Lytro has always been a company thinking about what the future of
imaging will be,” said Ted Schilowitz, Futurist at FOX Studios. “There
are a lot of companies that have been applying new technologies and
finding better ways to create cinematic content, and they are all
looking for better ways and better tools to achieve live action highly
immersive content. Lytro is focusing on getting a much bigger, better
and more sophisticated cinematography-level dataset that can then flow
through the VFX pipeline and modernize that world.”
Lytro Cinema represents a step function increase in terms of raw data capture and optical performance:
- The highest resolution video sensor ever designed, 755 RAW megapixels at up to 300 FPS
- Up to 16 stops of dynamic range and wide color gamut
- Integrated high resolution active scanning
By capturing the entire high resolution Light Field, Lytro Cinema is
the first system able to produce a Light Field Master. The richest
dataset in the history of the medium, the Light Field Master enables
creators to render content in multiple formats -- including IMAX®,
RealD® and traditional cinema and broadcast at variable frame rates and
shutter angles.
Lytro Cinema comprises a camera, server array for storage and
processing, which can also be done in the cloud, and software to edit
Light Field data. The entire system integrates into existing production
and post-production workflows, working in tandem with popular industry
standard tools. Watch a video about Lytro Cinema at
www.lytro.com/cinema#video.
“Life” the first short produced with Lytro Cinema in association with
The Virtual Reality Company (VRC) will premiere at the National
Association of Broadcasters (NAB) conference on Tuesday, April 19 at 4
p.m. PT at the Las Vegas Convention Center in Room S222. “Life” was
directed by Academy Award winner Robert Stromberg, Chief Creative
Officer at VRC and shot by David Stump, Chief Imaging Scientist at VRC.
