How to Expose and Degree HLG connected Your Sony Camera
S-Log up gets a mickle of attention when it comes to Sony photographic camera Picture Profiles. There is other option that just mightiness be a good option for many people: HLG. Hybrid-Lumber Gamma is a more standard HDR format that is almost ready-to-go with some devices. If you want to try it extinct you should understand how to best treat IT.
Exposing and grading different delineation profiles rump be tricky, so this helpful guide from Harv Video/Audio Stuff should act a very nice primer for HLG. Understanding how to overcome exposure will puddle life easier when you start grading.
This applies to many of Sony's cameras arsenic they have been using HLG for a good long while. In particular, though, you will get best results with 10-bit options like the a7 IV, a7S III, or FX3. HLG mightiness actually be fitter than log when it comes to 8-bit recording, so keep that in mind.
HLG, or Crossbreed-Log up Gamma, is a form of HDR that is intentional for spread applications where you might need to display either a conventional SDR icon or an HDR image exploitation the identical data pipeline. This gives it that Instant HDR branding where you can simply record in HLG and playback anywhere at the best character.
Still, at the end of the day IT is just another picture profile and has its own quirks for shooting and editing.
Starting with how to disclose information technology, Harv did what he is ill-used to doing and pushed the image as far atomic number 3 He could to overexpose it. In his example, He hit +2 stops overexposed by the in-camera meter. Adding some contrast and reduction exposure provided a pleasant image. He got similar results at just 1 stop over.
At "proper" pic the footage starts looking duller and duller and later on grading there is the potential for banding. Being underexposed doesn't work out to a fault well either with some odd color as well. More than 2 boodle overexposed also didn't work out overly healed.

It's some other reconciliation act for HLG photo, though it seems that 1-2 stops ended is a gratifying spot for it. Compared to S-Log3 in the same site, the log recording appeared to provide a more natural image. These results were repeated in both inside and unlikely footage.
HLG appears to get a much contrasty and saturated image. It definitely requires some additional work in post and non all of information technology is easily adjusted.
This isn't and then unexpected if you deal the HLG arch. The bottom of the curve is rectilineal but at the highlights, it has a log curve. This can make grading a spot more difficult since the antithetic areas can respond differently.
If you are editing HLG you will need to bring i sure that your NLE knows what information technology is practical with Beaver State you will arrest some weirdness. In Final Cut it is actually very easy to suffice and can give you a good image without much piece of work every bit long as you expose properly.
Compared to S-Log, HLG power hold you better results with 8-piece footage since IT requires less stretching in carry. Still, S-Log looks like it will deliver a more born image afterwards grading.

HLG is certainly easier to use of goods and services if you are going for a Rec.709 final product. S-Log3 also delivers much more than dynamic straddle. Plus, HLG still has its own pic recommendations that don't make it super spatulate to habituate and grading requires its own style.
Other things to consider are how S-Log3 is more wide supported with dissimilar looks and LUTs. So, if you have a favorite look you mightiness want to see if it'll work with HLG. Another aspect of HLG is that it isn't super grading friendly, though it should get some work. You just need a very light meet and make sure everything is ready properly before you take started.
Have you used HLG before? Are you leaving to try it out now?
