What is S-Log3? If you use a Sony Alpha camera like A7RV that supports S-Log3, this should be your preferred video mode. Picture Profile 9 is S-Log3 on the A7RV. By filming video with S-Log3, the video can be optimized within post-production with look-up tables (“LUTs”) and also by performing additional color correction. Think of S-Log3 for video like RAW for still photos. Filming in S-Log3 provides a lot more flexibility within post-production. #S-Log3 #SonyAlpha #A7RV #ILCE7RM5
