How to Expose for S-Log3 on the Sony a7S Deuce-ac and FX3
Among the biggest battles with mirrorless cameras gaining professional picture features has been how to best work with log footage. Think about how the initiative mirrorless cameras with a true log profile were stuck with 8-bit footage, which can be problematic when you try to push the tier. This resulted in a lot of people recommending overexposing and other trumpery.
Now, cameras care the a7S III and FX3 feature excellent quality codecs and newer log options, sol its another learning curve to puzzle out how to expose them. Working specifically with S-Log3 on the modish Sony cameras filmmaker Jacques Crafford has put collectively a pleasant scout happening proper vulnerability techniques.
This S-Log3 exposure guide volition lend oneself to even newer cameras, like the a7 IV. Jacques actually recommends using this profile all the time because of how much better it is in regards to things like high-power range. Soh, how should you use of goods and services IT?
In that location are a collection of tools available to label exposure:
- Using your eyes (Gamma Display Assist)
- Using photographic camera's metering modes
- Using zebras
- Using external monitor
Jacques doesn't recommend victimisation your eyes day in and day out since it is far from ideal, but also points out that having an external monitor, while nice, International Relations and Security Network't essential to get started.
Working inside or in harnessed light you can manipulation your eyes along with the Gamma Display Attend to setting. This will apply a display LUT that makes the image look "normal." If you are coming from monitoring footage this style with other profiles you leave feel at home, though you power want to manually adjust show brightness to +2 for consistency.
For metering modes, you will want to perplex to the Multi option as IT provides all-purpose metering of the total see. If your shot is fair stable so the metering modes are a good option. Generally, information technology has been recommended to overexpose by +1.7 to +2.0. Yet, connected these newer cameras releas with something closer to +1.0 can be better as it'll better represent the skin tones. Overexposing will save you from some noise in the shadows, but you testament lay off some home in the highlights.

Where the metering modes don't work is if you have extremely bright operating theatre dark areas weft a large destiny of the shot. In particular, bright highlights are a problem. Having the Dominicus in the back or merely a light will prank the meter into thinking IT is too bright. In these cases if you switch to the spot measure you rear check exact spots along the image, such as skin tones, to more accurately meter your shot.
If you need to check how the whole image looks and is exposed you should depend upon zebras. These will surfac when you gain dependable exposure levels. In Jacques case, he uses C1 to set a zebra to record at 50 with a +2 range. This will help you peg midtones as you can watch the zebras show upwards and know you might be on the way to newspaper clipping if they commencement to melt.
The C2 place setting is for checking the highlights. The standard mount is 75 with a +2 range. This shows that once your main subject is showing zebras you are hitting the upper berth limit. You will want to bump down when they are exhibit on the main content, though having a little show isn't the crack of doom either.

That's it for in-camera options, but if you want even off better tools you will need an extraneous monitor. Most of these will volunteer waveforms and false color. False color paints colors over the entire image representing different exposures. This way you can rapidly identify which areas are brighter or darker and exact how bright or coloured they actually are. Now you can make more precise adjustments on the tent-fly.
Victimization waveforms you can see the exposure across the entire scene and if you get been victimization information technology is color grading work you bequeath already know where exactly you wish your dependent to be. You will want to check the waveform before you apply a LUT, though you should too check it out after as fit.
Creating or using a LUT can make the integral editing procedure take a fraction of the time. It'll get you nearly there if you find or have a distinct look.
Do you have some best practices for exposing S-Log3 footage?
