Canon ’ s DSLR cameras get an HDR facelift
Atomos is working with UK-based cinematographer James Miller to bring C-Log Picture Profiles for Canon ’ s digital single-lens reflex cameras . By utilising Atomos ’ AtomHDR monitor / recorder , the Canon 5D Mark III and other Canon DSLR cameras are now high dynamic range ( HDR ) -capable . With the expanded dynamic range from the sensor enabled with C-Log , a monitor that enables users to accurately and easily expose for Log in the field is required , said Atomos .

High dynamic range ( HDR ) is capable of enhancing the creative palette ; it also acts as a creative tool to help content producers better tell their stories . Josephine Tan reveals more .

creativity to storytelling

Enabled by higher contrast display technologies , high dynamic range ( HDR ) enhances picture quality with greater contrast between shadow areas and highlights , deeper colour saturation and higher perceived sharpness .

Hiroyuki Takahama , assistant general manager , content creation solutions marketing , professional solutions company ( PSAP ), Sony Corporation of Hong Kong Limited , tells APB : “ HDR enables the transmission of cameracaptured dynamic range of luminance levels from the production process all the way to the consumer end without any degradation in the dynamic range .
“ For broadcasters and content producers , the appeal of HDR lies in its potential to produce high value-added content , not just for movies and dramas , but also for documentaries and other genres where reality and details are priorities , especially for live production .”
For instance , Sony supported a broadcaster of Vatican City State , Centro Televisivo Vaticano ( CTV – Vatican Television Centre ), in the broadcasting of the ceremony of the Closing of the Holy Door by his Holiness Pope Francis last December . The live event was delivered to global worshippers in 4K / Ultra HD ( UHD ) HDR .
The core of the technical infrastructure set-up for the broadcast comprised equipment from Sony , including 12 HDC-4300 cameras , an MVS-7000X production switcher and a PWS-4400 replay server system . As part of an endto-end 4K / UHD HDR live system , CTV also utilised a live production workflow — SR Live for HDR — which is a production infrastructure based on Sony ’ s S-Log3 system transfer function for the creation of 4K / UHD HDR and HD SDR ( standard dynamic range ) pictures .
Takahama explains : “ Sony first developed log gamma curves in 2000 for
the CineAlta series of digital motion picture cameras . These curves were designed to eliminate washout and black clipping when shooting while providing flexibility in post-production colour grading . S-Log3 is further developed and it defines a dynamic range of up to 4,000 %, enabling HDR performance and supporting live HDR broadcasts .”
HDR gives more room for storytelling , Takahama adds , and also empowers content creators with more creative freedom to better capture usable shots under challenging lighting conditions for productions such as documentaries or live events .
He continues : “ In Asia-Pacific , we see emerging interest for HDR . Key drivers that would encourage widespread HDR adoption include the availability of HDR-ready broadcast equipment for the end-to-end HDR workflow , which can be incorporated in existing workflows to reduce overall production costs , interoperability , future-proofing and open technical standardisation , among others .”
To provide content producers and cinematographers with a better understanding of the workflows in an HDR ecosystem , Sony , in conjunction with Singapore-based post-production house Mocha Chai Laboratories , conducted an HDR workshop in Singapore in early January this year .
Speaking at the workshop , independent cinematographer Lim Teck
Siang points out some of the key aspects when filming in HDR . He says : “ Besides having a camera that provides good dynamic range , the ability of shooting in RAW while managing the exposure levels are important factors . As HDR requires more attention to detailing and lighting , it places more demand in the production chain , from acquisition all the way to post-production stage .”
Agreeing with Lim , fellow cinematographer Kelvin Chew adds that the most significant change is the “ shift of power ”. He elaborates : “ HDR does not allow us as cinematographers to be pure specialists anymore . Apart from our initial knowledge in digital imaging , cinematographers now have to know a little about post production in order to deliver the best files .
“ Due to the expanded range that HDR offers , it also exposes imperfections easily . Unlike previously where we could fix these imperfections during the post-production stage , filming in HDR goes back to the fundamentals of filmmaking , where we have to pay careful attention to all the image details and layers .”
In driving demand and interest for HDR , TV manufacturers have been integrating this technology into their new TV sets . Video streaming service providers such as Amazon Prime Video and Netflix are also offering their content in 4K / UHD HDR , which requires consumers to pay a premium for these
