    The other reason to shoot over is how log curves are encoded with 10bit values. If you ever see what the curve looks like it’s flattens out as you get to the bottom. There are very few 10bit samples used for the stops at the very bottom of the curve. This is why even if a sensor had zero noise which is physically impossible you would still have banding and color loss if you lift up those stops too much. Ironically the noise actually helps hide those other imperfections down there.
    By shooting over you provide more coded samples in the shadows which means much better detail and color along with much less noise.
    There has always been this misconception that log was meant to be this one size fits all thing and should always be shot the same but that’s not true. Base exposure just means it’s what the designer of the log format felt was a good balance between shadow and highlight stops. Log formats tend to have a ton of highlight stops for two reasons.
    1. It was traditionally easier to market better dynamic range by showing less clipping in the highlights. Standard profile video clipped very early and log having usually 6 stops vs 3 stops of highlights visually made a huge impact.
    2. It’s always better to have more at the top and go down due to how digital sensors work and the signal to noise ratio and code values on a lot curve. Starting with a higher amount of highlight stops means we have more flexibility to shoot over to get the desired look we want. Doing the opposite would mean if we did want more highlight detail we would have to lift everything which would introduce worse results.
    Sony has Cine EI for a reason. BMD Pocket cameras shift how the stops are mapped based on ISO for a reason. It’s a completely normal and valid way to shoot. Others for years have called this ETTR which is the same concept. The problem with ETTR is there is no standard or consistency. One ends up with footage all over the place and it’s much more difficult to grade later to correct everything manually. It also creates very inconsistent look across shots where a high contrast scene will have a lot more noise than a low contrast scene will. It’s just too random. Defining the amount to shoot over is consistent. If values may clip the lighting or shading should be adjusted to lower that contrast of the environment. I’m also not as freaked out about clipping highlights as I used to be. It happens. Trust me the viewers are much less concerned about that then they are video that’s too dark or has too much noise. Clipping isn’t the fault of the camera. Clipping is the fault of not balancing the lighting of the scene or forcing the environment to be very high contrast for no reason. Like insisting on shooting an interview subject sitting in front of a window. Again no viewer cares about what’s going on outside the window. If they are then the entire point of the piece and interest in the subject has been lost. At that point clipped highlights are the least of the concerns. Even if one lights the subject really well to match the window it’s not a good composition and creates too much distraction for the viewer.

    Carsten back at it again with another banger. Honestly the +1.5/2 stops makes sense to me from a technical standpoint. Thus far I've mostly kept to using false color or just eye-ing it, but what you suggested with the lut definitely makes me want to try this method.

    Great video!
    Id' say it depends on the camera. Using a C70 with DGO, it's pointless to expose to the right. On my R5 on the other hand I always do that. Just keep in mind that over-exposing to the right (without clipping of course) will give the AF system a hard time.

    • @carstenschlag
      @carstenschlag  14 วันที่ผ่านมา

      Thanks man! Honestly I’m not too familiar with the c70. I’m interested as to why it would not help? (I’ve never shot on it before! ). And yeah auto focus definitely has some trouble depending how over you expose but honestly on the fx3 I’ve had very little trouble with it luckily. Really appreciate you watching man!

    • @CiprianTrip
      @CiprianTrip 14 วันที่ผ่านมา

      ​@@carstenschlag DGO, the dual gain output, means that the camera exposes at the same time for shadows and for highlights. It's not technically correct to say this, but it's like using two ISOs at the same time (not mistaking this for dual ISO, which is different). So exposing to the right means that you don't take advantage of the otherwise good and noiseless details in the shadows.
      Let's further discuss the autofocus issues. On my R5 I can record prores raw externally, and with the raw output you can overexpose by a lot, maybe 3-4 stops, without clipping the highlights. A simple PQ waveform on the Atomos Ninja can confirm that. But the AF system, which is otherwise a great one on the R5, will seek focus like crazy. So going all the way to the right in order to bring the highlights down in post and get lower noise is not always best if you need great AF.

    • @carstenschlag
      @carstenschlag  14 วันที่ผ่านมา

      Gotcha, that makes sense. Thanks! And yeah I could see that happening at 3-4 stops over. Have you tried just going 1-2 over ?

    The same applies in bright scenes effectively raising the EI to 2000 in a bright day while raise the clip point in the highlights as well, but because there’s no free lunch. You will loose some of the Detail in the shadows depending on how deep the shadows are.

      Zebras are great for skin tones as you can set the best IRE for skin. In this case you let highlights blow out in high contrast. You sometimes need to expose what you want to have exposed correctly

    Does ETTR work well when you have to bump your ISO over the 1st or 2st base ISO of your camera? For example - my 2nd base ISO is 4000. Is it worth to bump it to 12800 to get that extra 1.5-2stops of light? Or this method works well when you overexposing the image with 1) Wider aperture 2) More light

    • @carstenschlag
      @carstenschlag  12 วันที่ผ่านมา

      It would still work to an extent but pushing your iso 1.5 stops above your native iso would increase noise by a lot. So I’d say probably don’t do that. Lower aperture and more light will be your key here !! Appreciate you watching Aton!

    • @carstenschlag
      @carstenschlag  11 วันที่ผ่านมา

      Totally get your point! that would be true if you clip. But as long as you ride the line, you should be totally fine and be able to bring all that detail back. I use my waveforms and then go literally as close as I can to clipping without clipping and as long as you monitor that throughout the day you won’t lose any details when you pull it back down!
