RED TECH - Black Shade Calibration

[Jarred Land]

Nate is back with another RED TECH showing how to run a Black Shade Calibration which ensures clean and consistent pixel sensitivity across your entire image.

• What Black Shading is and why it is important
• How to perform a Black Shade Calibration
• Navigating to Menu - Settings - Maintenance - Calibrate - Sensor
• Differences between Manual and Auto Calibration
• Which calibration is recommended
• How often should it be done

Thanks! I need this..

Gotta love me some Nate

Thanks! This helps! A couple of things I always forget that I could still use refreshers on (or maybe I missed them in the vid!):

• Should we know ahead of time the compression rate we'll be filming at?
• If, say, we're going to shoot at 4K instead of 6K or 8K to get higher frame rates, should we be in that sensor crop for the calibration, or is it best to calibrate for the full sensor?

I don't own a Red camera , but thanks Nate!

Neither compression ratio nor resolution have an effect on what the black shading is doing, but higher compression ratios and lower resolutions will excentuate any issues that already exist.

This should be a sticky everywhere!

Thanks, Jarred!

I have a question. Why does RED recommend a manual calibration for Gemini, Helium, etc and auto for Dragon? What difference does it make?

Thank Jarred and thanks Nate for the video. This clarifies everything for me. I had to dig deep down in the forums to understand black shading but im glad I did as this made me understand my camera better. But with this video, it even makes it better.
