Hello dear cinematography community... I'm in preproduction for a short feature, which was planed to be shoot on the Alexa. On very short notice the production changed the camera and now we're going to shoot on the F55. (Don't even get me started about this topic…) Fortunately I got the possibility to shoot a test but I'm quite surprised about the noise at the blacks... The plan is to shoot the project on RAW with the AXS-R5, like we did during todays test. So we recorded 4K Raw, the Camera was set to S-Gamut3/S-Log3, toke a measurement and the exposer hit the 18% gray right to 38% on the Astro. Now, at home I was wondering about the results, opened the files with sony's RAW-VIEWER, Set the "Grading Color Space" at S-Gamut3/S-Log3 again and as one can see the 18% grey is right around 38% on the internal waveform again. But on exactly this image one can see, the in my opinion, heavy noise. It even shows some lines which almost look like bad compression… Does anybody have any advice, did I mix something up or is that the way it is? I kind of can't imagine. Thank you a lot for your posts!!! Philipp Künzli
