What is I Technology? '

(
$& /i Technology is a metadata protocol that enables fi lm and digital cameras to automatically record key lens data for every frame shot via electronics inside each * &()!

Whatever your fi nal product — feature, TV series, documentary, commercial, music video — the use of /i metadata will streamline production and make the FX process faster and more accurate during post production.

Current I Technology partners (as of this printing) /i Technology has received wide support in the industry from companies who are adopting /i Technology within their own hardware and software products. The growing list includes: Aaton, Andra, Angenieux, Arri, Atomos, AVID, Birger Engineering, Blackmagic Design, Canon, Cinematography Electronics, CMotion, Codex, CW Sonoderoptics, Element Technica, Fujinon, gbi, IB/E Optics, Mark Roberts Motion Control, OptiTek, Ovide, Panavision, Preston Cinema Systems, RED, Service Vision, Sony, The Foundry, The Pixel Farm, Transvideo, Vision Research, Zeiss. $"%# '
