- Harald Brendel, Head of Center of Competence Image Science, provides a deep dive into the new LogC4 Tonal Curve in the ALEXA 35, which has the capability to encode the increased dynamic range of the new sensor. He also talks about false color and exposure and compares LogC4 with LogC3.

i m not sure what is best in this presentation, logC4 curve for more efficient encoding for my next HDR grade of a movie, or the baritone voice of Harald. he really reminds me of my school headmaster and we immediately switch to a more attentive mode. we learn things more seriously if told by such voice.
great video guys
hello, loving your false colour sleeve. DM me where your purchase it from.
you would always expose to a grey card even if this left clear space at the top of the wfm (didnt wake yellow) in your scene. You would not expose right in this situation?
Hey Sam, it really depends on the preferences of the DP and the scene, we don't promote one specific way to exposure your image. If you're interested, we have a lot of detail on exposure including ETTR in our ARRI Dynamic Range Whitepaper available here: www.arri.com/en/learn-help/learn-help-camera-system/technical-downloads
@@ARRIChannel thanks Ill check it :)
@@ARRIChannel ettr seems fine. the bar scen 13 stops is nothing like a bar with a sea view which would really leave one in a difficult situation :)
All that technical mumbo jumbo, at the end its just a video camera.
I take you're not a colorist
hahaha. buy this one and exchange it with my pd150 which is a video camera too.
