Z CAM E2 vs. BMPCC 4K at 3 stops underexposure, pushed back and using noise reduction (temporal and spatial) in Resolve. The Z CAM image cannot be recovered as the stripes don’t go away (have a look at Johnnie’s shirt, for example).<\/p><\/div>\n

Z CAM E2 vs. BMPCC 4K at 4 stops underexposure, pushed back to zero and using temporal and spatial noise reduction in Resolve. Now also the BMPCC4K image cannot be recovered any longer (more easy to see during playback of the video files, not so easy to see in the scaled static images of this article).<\/p><\/div>\n
