Importance of black calibration and camera tempature
« on: September 21, 2020, 04:07:14 AM »
Hi fellow slow-motion film creators.

I have had the Chronos 2.1 HD for a few days now and been trying to figure out how to get the highest quality footage out of it.
After reading a bit on the forum I saw this post http://forum.krontech.ca/index.php?topic=458.msg2435#msg2435 and it has really helped me a lot with removing noise from my clips.

Here is a screenshot of 2 clips side by side. ( filmed a few frames with the lens cap on ) and boosted the exposure to 5 ( DNG files )
The bright "black" was filmed 2 min after camera startup and black calibration
The way more black was filmed 15 min after camera startup and a black calibration just before filming.

So to sum up, start the camera up well before shooting, and keep it on for the entire shoot. ( and follow JamesB's guide )
