I'm currently working on a multicamera Arri Alexa shot program. I received DNX 220X Avid media which works but it's log C and washed out as expected. I took the footage into Resolve 9 and applied a 3D LUT the DIT supplied and things look much better but still the setup is high in the 100 millivolt range and the peaks are in the 600 millivolt range on my Tek scope when I look at the Resolve lut baked in Avid DNX 220X media. I'm curious is it common with Alexa and other high end cameras to shoot with conservatively high blacks and low peaks. I tried applying the Resolve stand Arri to 709 Lut and it's about the same in levels. I even tried applying the same lut as an input and an output Lut simultaneously but that crushes the blacks and clips the whites. I'm fine with what I've got but just trying to learn more about why the Lut doesn't give me close to 0 millivolt blacks and 700 millivolt whites.
I also have the "Raw" Camera data in a folder named "CODEX_NEG" I assume this means they recorded to CODEX recorders and the files in the folder are .dpx 1.9MB in size. I tried opening a few in Photoshop CS3 and I get a black frame with the upper portion of the frame with Rainbow like Snow and most of the frame black. I read that Photoshop should open .dpx files. Could these be some sort of proprietary CODEX .dpx format? When I try to open them in Resolve 9 Resolve crashes when I click to view the file which Resolve seems to view as a clip and not individual stills. That part seems right but one click on the file icon and poof no more Resolve. Is there some Resolve support lacking in my Version 9 Resolve Lite that might be better in Ver 10 Lite. I can't seem to find the current legacy version of Resolve 9 on the black magic site even though I checked the show legacy box. Hmmm
I do have the Avid media so I can press on but I am trying to play like the big boys and access the Arri Raw/DPX files to see if the supplied Lut would translate better on that. Any suggestions are appreciated

I like Alexa because its specially designed to shoot feature films on large screen.
