Is GMA-7 lied to public about the HOLOGRAM TECHNOLOGY ?

GMA-7 has claimed that it used the hologram technology, which involves the use of 3D images and 360-degree cameras.

Anchor Jessica Soho, in a video posted at GMANews.tv, said they used the same technology employed by the Cable News Network (CNN) in its coverage of the 2008 US polls.

“Gumagamit ito [hologram] ng 3D image na pinapadala dito sa studio. Parang andito sila mismo sa studio, pero sa katunayan, nasa ibang lugar sila (This hologram uses a 3D image that is brought here in the studio. It’s as if they’re really here in the studio, when in fact, they’re in another place),” Soho said in the said video.

Lamdani, however, begged to differ. He said that GMA 7 and CNN didn’t use holograms but something which he called a “chroma key” technology.

“Channel 7 didn’t use a hologram. They used chroma key technology,” he said, adding: “Hologram is very expensive. You have to cover the person with 360-degree cameras and transport him. [GMA 7] used more of a chroma key because there’s no smooth camera movement. It’s not exactly what a hologram does.”

Chroma key, often referred to as green screen or blue screen, is defined as a “technique for composting 2 images or frames together in which a color from one image is removed, revealing another image behind it.”

The technology is commonly used for weather forecast broadcasts, where the presenter stands in front of a large blue or green background, which appears as a large map.
