New Alexa Models

Big news from ARRI, with new models and major upgrades available for all current models.

Internal RAW recording was mooted by ARRI some time ago with the modular internal design. Codex has filled that gap. This is a nice step forward in usability.

Interestingly, all the new models have the 4:3 sensor.

Log Gamma

In a discussion recently on the formerly useful DVInfo Forums I was trying to explain to some self appointed experts that they had the wrong impression of how Log Gamma encoding works.

Some misleading marketing graphs gave them the idea Log crushes the highlights, giving you even less information than than regular gamma curves, rather than evenly distributing the information giving roughly the same amount of data bits per stop. Effectively linearizing the stop per data bit bucket.

I gave up on the discussion quickly as it was evidently pointless, but I wish this Art Adams article had been available then.
