    Best tutorial on using zebra striping on the internet regardless of camera model. I've watched a dozen videos read manuals and explanations on the web and this explains the subject in a way that can be followed with confidence. Thank you.

    How are you manually changing the Iris, Shutter, and Gain on the screen like that? I've tried using the tiny wheel located on the back of my camera and the only way I can change these settings is my scrolling ON the screen itself. When you change it, it goes maroonish in color. I can't do this. Please explain if you don't mind. You made one of these changes at like 8:07 in.

    • @theunderscorecp
      @theunderscorecp 6 років тому

      I know you asked this 2 years ago, but for you or anyone that's curious...If you're using a similar Canon camera, you can go through the menus and assign different functions for the wheel. In this case, the exposure. You press the small button and it'll highlight, in orange, the active wheel function (F-stop, shutter, and gain--expressed in dB). Hope this helps!

    Thank you, but can we have another on outdoors no humans filming. What would the zebra pattern be when faced with green grass, trees and white fluffy cloud type day, ditto but with 10/10 clouds and ditto but just blue sky ? For establishing correct exposure when aimed at sky and aircraft for example. Also for street scene or a ground event such as vintage cars.

    • @UKAirscape
      @UKAirscape  7 років тому

      There is no single reference for a mixed scene eg I can't say "the cars should be xx" because it varies depending on their colour etc. Sky exposure will be different to street as well. Either use zebras set to 100% and expose for less than this (set it so that almost no zebras are showing except on the very very brightest bits) so that everything's not overblown (and tweak it when editing) or (better) buy a cheap 70% zebra card and hold that in front of the cam when setting levels, then carry on. Or, cheaper still, hold your hand in front of the cam (about 1m away, not right up against the lens) and expose on that at 70% (if you are Caucasian)

  • @ForViewingOnly
    @ForViewingOnly 10 років тому

    Thanks, this was a very helpful introduction. I was wondering why the camera doesn't always automatically adjust exposure so that whites never go over 100%, but I guess this might make the overall picture too dark if there is a small intense bright spot of light somewhere in the frame. So maybe sometimes you need to have some areas over 100% for the greater good of the picture?

    • @UKAirscape
      @UKAirscape  10 років тому +1

      ForViewingOnly Correct. In essence, because camera sensors can't record the entire dynamic range of some images (with very bright and very dark areas), you have to compromise on which part of the image is most important to you and set your exposure for that, accepting that this may mean another part of the image is darker or brighter than you would ideally like.
      Professional camcorders have settings that enable you to adjust how the camcorder records dark and bright areas by squishing the levels a bit to try to squeeze more in but consumer camcorders either don't do this or do it automatically so you have no control.

  • @alizelevy3331
    @alizelevy3331 7 років тому +1

    Hiya thanks for the amazing video. I'm using a bmpcc and just wondered what zebra setting approx works well for darker skin tones (Venus Williams for instance) do I go closer to the 100 marker or less than 70? Thanks for your help.

    • @UKAirscape
      @UKAirscape  7 років тому +1

      Much harder to say a precise value with darker skin because there can be so much variety. The darker the skin, the lower the exposure (ie less than 70)
      What you can do is purchase a "70% grey" lighting card (these are quite standard, sold in video and camera stores) and set the exposure for lighting that card, with the zebras at 70%. Then you can swap in any subject of any skin tone (leaving the exposure "as is") and it will pretty much be correct.

    Thanks

    • @UKAirscape
      @UKAirscape  8 років тому +1

      If there's no human subject in the photo then zebras are much less useful for exposure. What you can do (if your camcorder permits it) is set zebras to 90% or 100% and then bring the exposure up so that the sky / clouds are just starting to show zebras across them; they wil be the brightest bit of your image so a setting of 90%+ is right for them.
      Alternatively, stand someone in front of the camera such they they are in the same light as the landscape. Set the zebras based on that person on 70%. Move them out the way and take the shot :-)

    Could this be any good for a young low budget film maker? it's within my price range

    • @UKAirscape
      @UKAirscape  10 років тому

      Well, in the sense that it will shoot videos, yes you could do a basic film with it. And the art of a film is in the telling, not in the equipment you use. You could shoot a short film on a mobile phone if you wanted... :-)
      So a better answer is probably that it depends what kind of film you're making. For example DSLRs are much more awkward to use but work better in low light (moody atmospheric) situations; videocameras are more ergonomic and have better sound without buying shedloads of accessories and mucking about in the edit... so it sort of depends what you're plan is.

    • @Togmif

      so I have a canon t1i and I don't know if have this setting on there, by the way I was searching about zebra setting first to know what's it is .

    • @UKAirscape
      @UKAirscape  8 років тому

      OK, I see what he means. Yes, if you adjust the lighting until you see zebra stripes across the entire green screen then you know the whole thing is lit fairly evenly. Then you can re-adjust your camera and talent lighting for the correct exposure..

    Can I do this way. Set zebra at 80. once zebra appears, then back up until the zebra is gone, so then I know the skin tone is not reach 80. I just feel this way we will not see the distracting zebra patter at the face all the time.

    • @UKAirscape
      @UKAirscape  9 років тому

      You mean "back down" (less bright) not up but yes you could do that. Or in fact, best set to 75 if your camcorder allows it. Also, many camcorders will let you assign zebra on/off to a button so you can just toggle it on and off when needed.

  • @GetOutsideYourself
    @GetOutsideYourself 10 років тому

    Curious why this wouldn't also work at 70% with darker skin tones, adjusting the exposure as necessary.

    • @UKAirscape
      @UKAirscape  10 років тому

      Because how would you know how much adjustment was necessary? Darker skin tones come in a vast range of reflectances from, say, 30-40% (very dark skinned) up to mid-60s (very light) so you can't use a generic setting as you can with Caucasian tones which tend to be a consistent 70% ish. And unless your camcorder gives you a percentage exposure reading, you're still going to be no more informed about whether you've set the exposure correctly for their shade or not.
      What you need is a constant reference level. Therefore what you can do is either:
      a) Put a Caucasian person under the lighting that you propose to use, set the exposure on them at 70% zebra and then ask the darker-skinned person to swap. This can seem a bit rude though.
      b) Put the subject in place and ask them to hold up a plain white piece of paper (which should reflect almost all the light that falls on it ie 100%) in front of their face (where the main light will be falling). Set your zebra pattern to 100% and expose until the paper is showing zebras. You have now set the exposure correctly for the amount falling on the subject's face.

    • @GetOutsideYourself
      @GetOutsideYourself 10 років тому

      UKAirscape Good tips, thank you. So as I understand your explanation, the ideal exposure on a darker skinned person is a level that would be 70% on a light skinned person. Just seems to me that would under-expose a darker complexed face. Am I missing something here? Wouldn't we want to up the exposure versus a lighter-toned face to bring out more under-exposed details?

    • @UKAirscape
      @UKAirscape  10 років тому

      Well, no, not really but yes possibly (!).
      Strictly speaking if your subject *is* very dark skinned then you want them to appear dark in the recorded image because that's how they are in the real world! They are that dark compared to someone who's lighter skinned. Hence why calibrating your 100% zebra to 100% in camera shows your subject at their true shade.
      Now, that said, it may be that your judgement is that you do want to lift the levels a little to bring out some detail but it's a judgement call and do be careful not to overdo it. You run the risk of making them appear unrealistically bright and you're also going to blow out (overexpose) any background that is light.

    • @UKAirscape
      @UKAirscape  9 років тому

      Yes. Although there's actually scope to go up to 107% provided that you bring the levels back within range during editing.

  • @jonasnilaus
    @jonasnilaus 10 років тому

    Most of this is overexposed (no wonder, when you gain 6 db in a sunlit room!)
    If you set Zebra at 70, and find bars in most of the persons face, it's overexposed and shiny. Only very few bars - if any - should show at this level. I got the following off "Hdwarrior" :
    Skin tones usually fall between 55 and 65% for a very natural, well detailed, chroma-rich look. At 70% skin will start to “shine.” At 75% you are loosing detail, and at 80% most all the detail is gone.
    In conclusion : set zebra to 70, when the bars show on the face of the person in front of the camera, turn it down ever so slightly and - boom - good exposure :-)

    • @UKAirscape
      @UKAirscape  10 років тому

      ***** Hi. Thanks for the comment. I agree with HDW that above 70% you start to lose detail for sure. The recorded footage on the HF-G25 actually looked fine - remember that how it looks on the LCD screen, especially when filmed off that by another camcorder, will not be representative of the recorded file. Also, given the zoom level in play, there was no further open iris movement to be had which is why the gain was stepping up when the exposure control was adjusted (the room was not as sunlit as my description made it sound). I could have dialled it down a fraction more but only by about 1dB - notice that when the gain's at 5dB, there's only the tiniest bit of zebra marking showing on her cheek.

    • @jonasnilaus
      @jonasnilaus 10 років тому

      Fair enough, I still think that 70% is a bit high, better to turn down a bit when you hit that mark. Otherwise people will look shiny :-)

      There is no single definitive answer since non-white skin tones can have a range of darkness. I would, as I think I mentioned in the video, set it to 70% on a caucasian subject or test card, and then it is set correctly for anything else in that same lighting, whatever their skin tones.
