Blown out material from BMD 2.5 K camera
Hi,
When loading material from the BMD 2.5K camera shot in raw into Resolve, the files are totally blown out.
They are easy to recover by pulling down the gain control, but I find this strange.
The DOP says that nothing was clipped on his histogram, and I guess he’s right as its that easy to recover by using the gain controll. Its like there are recorded data far beyond the 255 as can be pulled back. Im used to Red and Alexa where everything over 255 is clipped. This is not.
Any idea what is going on?stig

What’s this “255?” There cannot be any values over 255 in 8-bit. This is likely a re-scaling issue.

Thanks, it was a scaling issue.

How is your exposure set up in the Camera Raw Project controls? If you have an excessively high setting, this could conceivably clip out the whites. I routinely drop the master project settings down a notch just to avoid this problem with all raw formats — for example, I’ll knock 800 ISO projects down to maybe 500 to salvage the whites. If they’re really underexposed, then I’ll go in and manually bring them back to 800 if necessary.
