The crushed shadows were a stylistic choice but I will grade the image again. If you look at the clips under a waveform and vectorscope you will see that nothing is blown out. I made sure to expose below the clipping point to prevent any kind of overexposure. I chose to shoot this in LOG over REC709 for multiple reasons. 1) you are shooting at the native iso and also rate the ISO slower by over exposing. 3 stops overexposed at 800 iso is an image equivalent to one shot at 100iso 2) the cameras dynamic range doesn’t chance with any picture profile only the gain does. You will always get a better signal to noise ratio over a rec709 who’s noise floor is hidden in the shadows and will quickly appear when raising them in post. 3) sgamut3.cine works better with color than standard rec709 profiles because of how it handles saturation. After around 40 ire I believe colors don’t get more saturated they just get brighter like film. That color science is not present in any other profile. 4) Im not having the issue with loss of color data or banding because I raise the in camera saturation. SLOG3 white papers suggest to raise in camera saturation to emulate printed film. In post it preserves more color information. The SLOG3 & cineon white papers both state they were made to support 8,10 & 12 bit data so the 8bit argument when shooting log is null and void. Expose up to assign the higher code values of the codec to the image and you are fine. So in my experience there are significant gain in using LOG profiles over REC709 under the right lighting conditions. I will regrade this to look flatter. I have never experienced the banding problem. Do you see it present in my footage ? Im not sure if I missed it but I didn’t see ang banding when I shot or graded this Absolutely right. There is no exposure trick to get more color depth and this is why you raise the in camera saturation. Increasing the saturation holds onto more color information. SGAMUT3 is large enough to support this extra color info without blowing out a color channel. You can desaturate in post Now if only I could apply this to my GH4 internal V-LogL - especially the part about no banding... Quote Link to comment Share on other sites More sharing options...
