    Yeh…i always have this problem went shoot slog

  • Reply Saphir3000 February 3, 2020 at 1:54 pm

    I simply use some well designed LUT's that I bought and then I just fine tune it from there. Never had any problems with blotchy skin or stuff like that since I don't really wanna deal with color grading it from scratch anyway 😀

    DUNNA DID IT! 🙂 🙂 🙂

    You don’t get usable dynamic range if you going to expose like that because it’s way underexposed you need to expose your shadows until they above 40 ire it’s or overexpose for 2 stops if you don’t know how to deal with histogram or waveforms

  • Reply Moise Nicolas February 3, 2020 at 2:13 pm

    Wait how’d you get S-Log at 500 iso mine doesn’t go under 800

  • Reply Bobby Prado February 3, 2020 at 2:47 pm

    Hey man do you have a video explaining S-Log and or Sony Picture Profiles? I’ve been just using it in my camera and playing with it but I wanna know everything about it

  • Reply André Nascimento February 3, 2020 at 2:52 pm

    The problem when shooting SLog is that you have to transform it into rec709, SLog isn’t just less contrast and less saturation, it’s a setting that maps luminance and color values in a different way. Increasing the saturation in the s-gamut color space is like trying to fit a triangle in a square hole in one of those kid’s games: even if you manage it it’s not how it’s supposed to be done. Try looking around for slog2 to rec709 correction/conversion luts, a personal favourite is Joel Famularo’s Phantom look pack, or just try installing DaVinci Resolve, it already comes with some nice luts to transform color spaces.

    Also, if you look for the Phantom Lut pack creators Vimeo he has a couple of videos explaining how to expose for skin tones especially for use with his luts. And there’s also a lot of information on reddit, particularly on subreddits like r/cinematography and r/filmmakers

    Thanks a lot for this vid! What's your bet on HLG3 vs. SLOG2 with all cranked up saturation?

  • Reply Dunna Did It February 3, 2020 at 3:28 pm

    *A little disclaimer before you comment* A lot of the explanations in this video are very simplified for the sake of getting to the point and being a bit more accessible to beginners (who a lot of my audience are). I do understand that S-LOG and S-Gamut are not just decreasing contrast and saturation (I tried to make that clear at 5:48). I have tried overexposing for 2 stops, I've tried several different LUTS designed to correct/convert S-LOG/S-GAMUT to REC709 (like the ones I showed in the video and more). Unfortunately, even with those tools, the problems still persisted or new ones arose. However, when I applied this fix (increasing the saturation in S-LOG/S-GAMUT in camera) and then applied those same correction/conversion LUTS. The problem was significantly reduced and sometimes eliminated. My belief is that the problem is not actually S-LOG but the sony codec and bit rate issue. I know I titled it "S-LOG2 Sucks", but I think it probably only sucks at 8 bit 4:2:0 100mbps and as soon as Sony gives us 10 bit 4:2:2… this whole fix will probably be unnecessary. I hope that clears things up for those of you who were about to be like "THIS IDIOT HAS NO IDEA WHAT HE'S TALKING ABOUT"

    Okay bye bye!

    Great video Dunna. You should do a follow up with your whole grading process.

  • Reply Living Proof Filmz February 3, 2020 at 4:05 pm

    thanks dude! i'm going to give this a shot. i stopped using s-log a long time ago as well because of this same issue. well, this and i was also getting a lot of noise/grain in my footage when using s-log. I started using cine 2 and cine4 and got a way better result. I'm still shooting on the a6300 so i feel ya on that 8 bit. i need to just step it up already and upgrade cameras. i swear i feel like i've been back and forth with picture profiles and settings since i bought this camera a few years back. haha.. thanks again bro. i'll give this a shot.

    Definitely going to give this a rip! Going on a trip this week, and I'm only bring the a6300, so this will be cool to try!

  • Reply Paul Feinberg February 3, 2020 at 4:30 pm

    Thats some good tips right there. I have not been wanting to mess with S-Log so I have been shooting in HLG2. Maybe one day I will be brave lol! Nice video!

  • Reply John Spirou February 3, 2020 at 4:31 pm

    you dont understand that you cant have both the talent and the windows exposured right! You have to choose…and the most times you want your talent exposured right. That means you HAVE to exposure for skin tones… so zebra at 70% there. Windows doesnt matter at all. If you want the windows too, you have to light up the talent.

    after using my a6300 for 2 years+ now, i finally can use my slog2! thanks so much for the help dude!

  • Reply Jack Stolz February 3, 2020 at 10:31 pm

    Ok. I gotta try this. I'm SO colorblind that the yellow/ red skin blotches don't even register for me, so fixing them has been IMPOSSIBLE. I can tell something isnt right, but can't get there. Cine 4 has been good for me, and looks similar to the Dunna Fix so I'll have to try your method and see how my eyes fare!

  • Reply TimmySparrow February 3, 2020 at 10:33 pm

    Heck yes! I thought I was the only one doing this! Now I have some affirmation from a seasoned pro! 😆 I coined the name "Saturalog" for this method and I've been using it for years! It actually even helps a lot with slog 3 even on the 8 bit codec! Try slog 3 with sgamut.cine3 with 32 saturation and it's actually usable with a TON more DR! You can also use the "pro" color mode with the slog gammas and get even more saturation out of it before the camera turns it into a difficult 8 bit file!

    I recently shot a music video in slog2 and ran into some of the same problems you're seeing. I was able to resolve my issues by using the slog2 to rec709 utility LUT from iwltbap.
    I don't know if you've tried that one specifically, but it worked wonders for me.
    I basically just used that LUT and then used the curves to adjust contrast and exposure and it looked perfect. Worth trying out if you haven't already!

  • Reply Jussi Alexander February 4, 2020 at 1:37 am

    I've never really enjoyed the workflow of color correcting and colorgrading S-Log. Also my results have not really been the as good as I wanted, but that saturation tip seems helpful. Thanks! 👍

  • Reply Matt Doddato February 4, 2020 at 2:09 am

    This was a great video. I've recently switched over to Sony and this issue is something that I've struggled with. Glad to see the "expose your face with zebras at 70" method, I just talked about that in my video yesterday because it helped me finally get a better overall exposure in S-LOG2. Will have to try the saturation setting as well, thanks!

    The Fujifilm X-T3 does this same patchiness in f-log. I'm going to try this hack in Fuji world to see if it helps there too.

  • Reply Gilbert Flores February 4, 2020 at 6:12 am

    I just ordered a a6600 will the slog on that camera have the same problem ?

  • Reply Shane Nixon February 4, 2020 at 6:28 am

    I have / had a similar problem with my GH4 and V-Log. When I throw on the rec709 lut from Panasonic some of the footage is way too red and hard to fix. I found it mostly when the white balance was slightly off. Somebody made a fixed version of the rec709 lut that dials back the saturation heaps that fixes it a bit. But mostly I try to get the WB right. Sometimes if it is really bad I try and fix it without a lut at all. Now I've upgraded to the GH5 but I am yet to grade any of that luscious 10 bit footage but I can't wait to try. I still have a bucketload of 8 bit GH4 footage to grade though. Thanks Dunna this was great 😀

    Nice Vid! I've opted the last several months to simply shoot in ITU709 in both with some slight tweaks. For my workflow and needs…. punchy color, high contrast and sharpness SOC are needed and the 6300 does a phenomenal job for that 🙂 I messed around for a year with varying results with LOG but at the end of the day I'm not a colorist and certainly not in an 8bit space and ultimately my stock footage sales actually increased just doing it this way… 🙂

    Hey, i have a Sony A6500 and i'm using the setting from EOSHD Pro LOG for Sony Cameras for some time now. Since i get the settings all my problems with SLOG-2 are gone, simply overexpose for 1 till 2 stops, depends on the surroundings and the look you are after.

  • Reply AI Pete February 5, 2020 at 11:22 am

    if you use s-log in 8bit , try to work with aces color space that will blow your mind

    you should try and use HLG3 check out Gerald Undone's video on the topic. For me, on the A7iii and A6400 HLG3 is SOOO Much better with the flexiblity and rang of SLOG, but not the Macro blocking and the best part is you can use ISO 125!

  • Reply mohammad mehdi February 5, 2020 at 8:24 pm

    So Dunna I had the same difficulty when I first got my sony a6500 and shooting slog2. I totally ditched it and used cine instead. But a few weeks ago I did a huge research into it and finally managed to figure it out. Actually slog2 has two distinct advantages. Increased dynamic rage and BIGGER GAMUT (AKA S-GAMUT) it is not just desaturated, It is actually wider than Rec709. Long story short you have to first use a correction LUT to map it back to Rec709 using sony's official correction lut (instead of bumping the saturation slider) this way the gamut part is corrected and then use s-curve to correct the dynamic range and contrast. Trust me it works like a charm 😉

    You've discovered something just like i did 1 year ago. And you know what, I still got rid of S-Log. You know Why?
    BEcause why spend times & frustration to go through hell for all those issue, when you can just have the same result very easily, nice contrast, nice saturation, with a diffrent picture profile?

  • Reply Ompire February 7, 2020 at 11:40 am

    I've been there too… but the problem with slog is not SLOG itself. It is sony mirrorless lineup that just records 8 bit 4:2:0 and literally don't have enough colors and luminance values to push slog to its real potential.

    And not to mention that you only can record 100mb/s which SUCKS SO BAD.
    I moved to my gh5s from my a6300 and I could not be happier😃

    I am pretty baffled how there just isn't some video on an official sony page that shows "THIS SLOG, THIS IS HOW IT WORKS, THIS IS HOW YOU EXPOSE" etc. Just gave up and use cine, mainly out of fear of shooting a project and ending with unusable grainy video.

    Have you tried HLG? I’d be interested in seeing your results with that profile (or a tweaked version of it) 👍

    Man oh man..! I have watched tons of videos on s-log because I’ve been having a similar problem where I was seeing that blotchiness in kinda purplish tones on my skin and none of the videos gave it like this… all those pro’s must be aware of it but none of them mentioned. Well actually I’ve stumbled upon a blog post from cody blue only I guess saying he prefers cranking up the saturation and it looks better but didn’t really explain why. And thinking my problem was totally unrelated, I thought it could have gone worse so didn’t even bother giving it a try. I was looking for cine4 profiles now but this video just opened a whole new thing for slog again. Thanks a lot man… great work. Subbed… 🙂
