Would shooting through IRND Filters help to even out the blacks reaching the sensor?

Hi Andrew-

 

You’re thinking about black shading, not black balance. Black balance will just make sure black is black. Black shading is about eliminating noise and fixed patterns.

Yes, sorry about the examples, they are not great, here’s one more, I have increased the brightness and raised the shadow areas just to so you can see the pattern.  I hasten to add this is only to see the lines, forget the colours etc.  One of my thoughts was that its to do with a black balance, which isn’t possible, I then thought perhaps the temperature of the sensor might be an issue, I know when shooting Phantom some techs have told me they want the camera to ‘warm up”  

 

My main question is , what is producing the pattern, obviously the sensor, but what part of it and why?

I agree 100% with Alister: the frames are too small to judge (😃) but my initial assumption would be that it’s fixed pattern noise. Most cameras address this with a black balance. If that’s not an option here you’ll need to do it in post.

Thanks Alister, seems I forgot to mention one important thing, it was lit with sunlight alone, so its not that.
