How Do You Expose S-Cinetone with the FX6/FX3/A7SIII

exposing-cinetone-600x316 How Do You Expose S-Cinetone with the FX6/FX3/A7SIIILots of people have been asking about how to expose S-Cinetone, whether with the FX9, FX6, A7SIII or the FX3.

The short answers is:  So that it looks nice!

S-Cinetone has a variable toe and knee. So exposing it brighter results in not only a brighter image but also an image with flatter skin tones and less shadow contrast, overall looking more video like.

Exposing a little bit darker results in a more contrasty film like image. Faces and skin tones have more texture. There is no one optimum exposure level. A white card  could be anywhere between 78% and 88% depending on the look you want.  Typical skin tones will vary from between anywhere between 55% and 75%.

Personally I like the way S-Cinetone looks when it’s exposed with Skin tones at around 63% and white at around 81%.

See the video I on S-Cinetone on the FX9 for more details as it all applies equally to the FX9 and FX6 as well as the A7SIII and FX3. The only small difference is that the base ISO’s are a little different between each camera.

 

Broadcast safe and direct to air using S-CinEtone and the FX9

S-Cinetone is a combination of both a gamma curve and colour matrix. So you can mix different gammas with the S-Cinetone matrix to get the same colour palette but with different contrast and brightness ranges.

The FX9’s default gamma curve is labelled “original” in the camera’s paint settings. This gamma curve is the closest to the look that the s709 “Venice” LUT provides. One important thing to note about this gamma curve is that it records using full range, so it can exceed 100% and goes all the way up to 109%. This means that it may not be suitable for some broadcast applications where the footage will go direct to air without any grading or post production adjustment.

If you do need a broadcast safe output then you should consider using Hypergamma 1 with the S-Cinetone matrix. The look is very similar to the original matrix, but Hypergamma 1 never exceeds 100% so it is “broadcast safe”.
