kye Posted October 2, 2023 Share Posted October 2, 2023 Record a shot of the blue sky, or a wall perhaps? Anything that isn't 0 or 100% in any colour should be visible in that test clip I would imagine. Quote Link to comment Share on other sites More sharing options...

I don't think it matters as long as it's not white or black. Even if they just recorded a test clip where they point it at different stuff. If there was a pixel stuck on or off you'd notice it pretty easily I'd imagine. "Film something bright and something dark" might be relatively simple advice to understand?
