F3: Using S-Log

[Lenilenapi]

Interesting use of the histogram to detect flickering but aside from that I would have to agree that I find useless on an F3. Not to useful on a DSLR either for that matter.
It works great on a RED but RED has different exposure issues because all steps are equal.

Interesting about using the histogram for detecting flicker. I've noticed that before with HMIs and wondered about it.

Let's face it, when setting exposure you use every means you've got in the available time, right? And of course the zebras are the main other means along with the histogram, camera's spot meter, a reflected light meter and your own eye. With slog I've followed the rule of never over exposing and as always the zebras are essential. But a histogram is also handy and in the situation mentioned above of shooting direct to SXS cards where low contrast can be an issue, a histogram will show that plainly.

Probably, a better question is: when and how can a histogram give you the wrong information?

A histogram can give you the wrong information in low light if it is in full RGB mode.
You need to look specifically at the Blue channel in that situation. It may be up to two stops underexposed otherwise.

Just wondering what others are using to monitor a shot, with the camera set to record in S-Log, maybe outside you use a grey card to set exposure for your foreground scene yet still in the background there may be a car in sunlight or the sky is a bright overcast and you want to make sure you are not clipping your highlights or crushing your blacks. I’m assuming many are using good quality monitors with waveform monitoring built in. Just wondering what type of monitors you’re using?

TV Logic using the wave form, camera spot check.

Sure.. if the outdoor scene doesnt have extreme contrast I use a gray card to expose at 38 IRE. If there is a bright sky or other important element in the shot I'll put it just below 109, even then chances are the foreground wont be below 38. That is the beauty of S-Log. Of course dont shoot in to the sun with your subject in full silhouette. For monitoring I used to just use the built in zebra's and spot meter.

While it is possible to shoot & grade S-Log from internal recording, I would highly recommend using a external recorder if you know you'll be pushing the footage hard in post.
