Pawel, I agree with this completely. While all cameras are not equal that does not mean that perfect cameras exist. I’m not sure how you’d even define that. Alfonso’s tests are very thorough, and whil

The camera choice is all too often driven by ego and politics, rather than camera capabilities. This can be true. I once had to shoot a marketing product roll-out where the client mandated we shoot in

The differences that exist between the very best and the least good of the large sensor cameras are small. Small enough that give them to a competent operator, shoot some random typical scenes with th

Hi Cynthia- If there’s enough IR pollution then yes, the blacks would be contaminated along with everything else. At lower levels only fabrics and certain materials will noticeably change color. In th

Andrew, I can’t answer that as I don’t know that camera well enough, or at all really. I do know that black shading will often solve that issue in other cameras. Sorry! -Art __________________________

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. -Art _________________

Just to be pedantically pedantic, it’s black shading that addresses fixed pattern noise. My understand is that you’re creating an offset map that addresses unevenness in noise across the sensor, often

>>>A grey card helps identify the white point of the scene. How the camera reacts to that is camera dependent. That’s a better way of saying that. And, as best I can tell, that’s just a gain adjustmen

I would think it would send raw back. Processing the image before transmission seems like a waste of processing power and energy when you could do it just as easily on Earth, plus you can update the p

>>>A grey card seemed to work well for a long time…. That’s because film has the color science baked in. If you print the gray card as neutral then everything else falls in line (depending on the proc

As usual, it looks much darker on Vimeo than it does on my system. Hi Geoff- I wonder if that has to do with the old Quicktime gamma bug. When I was a freelancer I found that the X264 encoder got arou

Not often, but the latest repair ( not sensor related) at Arri for one of our Alexa Mini’s showed one dead pixel, which apparently they are able to hide. This is standard procedure in most cameras. So

In a bayer pattern, there are 4 subpixels per pixel. They capture data as Y, but they are already 'colored' by a microfilter. Debayering assignes RGB values by essentially transforming the 4xY into RG

>I think there’s a very simple solution for the problematic highlights in HDR. “Default White”. In linear terms, this is basically 2-2.5 stops brighter than middle gray. Beyond that, you’re in HDR ter
