Content in High Definition
New technologies undoubtedly influence the way journalists and especially producers work in studios. This session chaired by Jack Nadarajah, Deputy Director of Program Content and Acting Director of Strategic Development Department, at Radio Television Malaysia (RTM) throws some light on lighting techniques in the digital era.
LED Revolution in Broadcast Lighting
Ajeet Khare , MD Canara Lighting Industries Pvt Ltd, India shed sufficient light on LED technology which enables broadcasters present at the session to understand better lighting techniques and characteristics in TV studios. He recalled the use of Halogen some years back which created excessive heat and more power was needed. Today most broadcasters worldwide are using hybrid lighting, a mixture of Halogen and LED.
Ajeet Khare said that LED is a green technology and it has arrived at a time where global warming is of great concern. He stated that with LED technology only 20 per cent power consumption is needed, there is no heat radiation and only a reasonable level of air-conditioning is required. Other characteristics include very long lamp life, consistent colour temperature, presenters feel more comfortable and no UV rays. He added that big TV organisations like BBC has moved to LED technology and has confirmed the tremendous advantage in terms of costs. So, Ajeet Khare concluded that broadcasters worldwide tend to Go Green as far as studio lighting is concerned.
Making HDTV Drama in South Korea
Korean Broadcasting Service (KBS) has good experience in the production of HD content. Today, the whole South Korean population is in a position to receive HD signal which is known for its high Resolution (SDTV = 720 x 468, HDTV = 1920 x 1080). Lighting is one of the key factors in the production of HD programmes. Ryoon-Sang Yoon, Senior TV Production Engineer, KBS, explained the colour temperature conversion in this technology: No change in White, Red can be seen more and becomes an abundant colour. Green becomes soft and a moderate colour.
He underlines also the importance of Make-Up in HDTV due the skin details which appear easily on the screen. Concerning the colour setting, producers should be careful about the depth of the Field where intensity of light and camera focus should not be a problem.
He concludes that “it’s high time to acquire maximum knowledge on HDTV so as to get prepared for the UHD era.”
Lighting Not a Technology BUT more like a Design
Yun Hwan Jeong, ABU Senior Producer, former Director of Cultural Department at EBS in South Korea thinks that lighting in broadcasting is a design beyond a technology. It is even an art.
He has worked for more than 20 years as a TV Producer and he is well known in his country for having produced a famous musical programme, Space Gong-Gam, which has a Korean meaning for sharing feeling, emotion and contemporary culture with people.
Space Gong-Gam is a kind of music format to introduce all kinds of popular music to the viewers such as Pop, Rock, Jazz, Hip-Hop, Classic and World Music. A musician comes on stage to play his music and to share emotions with the audience each time. One of the reasons why this programme was so popular is because the producer through lighting techniques gives the impression that the audience is in a club rather than a TV studio
Yun Hwan Jeong concluded his presentation with an old saying in animation PIXAR.
“Art Challenges Technology. Technology Inspires the Art.” That’s the way he thinks for more creative lighting.
