Thank you Martin,
I read an article about hyperspectral chip made from 100 strips of different narrow band filters.
I think % 50 of them cover visible spectrum. If each strip can be recorded with 20 mb quality , 1 frame makes 1 gigabytes of information.
If it records 1 hour , it makes 3600 gigabytes , 3 hour movie makes 10000 gigabytes. If in this time range when achiving to record that in single DVD , it would increase to record 2000 bands. That makes 72000 gigabytes.
It would take 50 years to achive to playback the Stalker movie on a pc with all details.

I have sent a mail to Pathe and waiting their answer.
