Calibrating for general use
Posted: Mon Jul 09, 2012 6:02 pm
I'm fairly new to Neat Video and as such I followed the tutorials with interest. They didn't help all that much - as the video I'd shot was largely unsuitable for calibration.
For those with a similar problem this solution worked well for me.
Use the tutorial videos certainly - but, and this the crucial bit - go out and shoot video specifically for calibration.
Set your ISO at max (6400, 12800, etc.) and shoot as much as you can at as many exposures as you can making sure you don't blow highlights OR drop into the shadow area. If you camera can show live curves, all the better.
It helps (if you can) to switch off anything like auto contrast on your camera which might harden the curves too much.
Shoot full frames of each exposure - at least highlight, mid tone (grey) and shadows making sure the subject is completely out of focus - you don't want any detail as that hides the noise.
When you get back, create and save your profile - even using several different shots - I used five in total - to create your profile and save it.
The results were astonishing; and while your mileage may vary, I hope this helps.
