Exposing for S-Log3 on the A7S III S-Log is a log curve which has been specially optimised for digital motion picture cameras to maximise the performance of the image sensor. It is the best choice for shooting in 10-bit, but if you are shooting with an 8-bit codec it should be avoided as it will cause issues with banding and compression artifacts. S-Log2 is good, but S-Log3 is less contrasty and easier to grade.
LONG S LOG 3 LUT SKIN
6 If you deliberately over expose S-log2 or s-Log3 by 1.5 stops both should be recording skin tones at approx the same level of 60% which is the point where the two curves cross-over, so between correctly exposed and 1.5 stops over S-log3 skin tone will need less movement than S-log2, in addition S-log3 will be recording the darker tones at a. The Wolfcrow System simplifies exposing S-Log3 to just two numbers! settings. Get consistent and filmic exposure every single time with these advanced tips and tricks.
The definitive guide to exposing and working with S-Log3 - from the guy who has shot and graded almost every type of log there is.
When you adjust the shooting exposure with set to and then switch to, a low-contrast image will be displayed with ITU709 contrast applied To measure the brightness of a grey card, 41% is a gamma curve for easily previewing a level of gradation equivalent to that of an image recorded using or and graded to ITU709. To measure the brightness of a white card you will need to set the level to 61%. But you will need to set the Zebra level to the right custom level depending on what you want to measure. It has characteristics closer to those of scanned film With the FX3 and a7S III, zebras are in my opinion the best way to check your S-Log3 exposure levels. S-Log3 allows for better reproduction of gradation characteristics in shadows and the mid-tone range than S-Log2. What is S-Log (S-Log2/S-Log3)? S-Log is a gamma curve with a wide dynamic range optimized under the assumption that grading will be performed in the post-production process.
