Hi there!

As we're more used to Alexa footage here, I just wanted to ask about RED, as I 
have some footage here that let's me wonder about the capabilities of the RED 
camera:

I have some shots with fire, sun, lamps, etc. in my images. Shot with EPIC-X. 
When importing them into Nuke and linearizing them, I always see that these 
bright highlights are clipping at around a value of 3 to 4 (depending on the 
channel).

This happens, no matter how I treat the footage:
- importing the original R3D file in Nuke and use "half float linear" as gamma 
space and 'linear' as the Read colorspace
- importing the original R3D file in Nuke and use "RedlogFilm" as gamma space 
and 'cineon' (or PlogLin) as the Read colorspace
- converting the R3D in RedCine X Pro to DPX with RedlogFilm and importing with 
'cineon' or 'PlogLin'
- converting the R3D in RedCine X Pro to EXR with ACES and importing with 
'linear'

Having similar takes shot with the Alexa as AlexaLogC, bright highlights will 
clip at a value of 54!

I don't want to start a 'war' Alexa vs. RED, but just wanted to know if this 
really is 'normal', so the RED will not deliver higher values, or if there is 
something wrong/strange is going on here.

Thanks for your help,

Abraham
