Just an update to this video. Last month I filmed some new "Korean FAQ" episodes and made a few changes to this setup - namely I upgraded my lighting equipment (I made a video about the lights I'm using in the 2nd episode of this "Backstage" series) and that alone had a really noticeable improvement in the quality of my lightboard. With stronger lights (instead of the can lights used for this video), I was able to turn up the aperture a bit higher to make the colors more vibrant and everything clearer. In the future I'd also like to experiment with different light positions to make myself stand out more in front of the black background. I'll make another update if things change majorly.

To explain what is happening by changing the aperture from what you call "lower" to "high", you are changing it from a bigger (f/3.5) opening in your lens to a smaller (f/10) opening in your lens-Confusing numbering? Not really: Think of it as a fraction, where f/3.5 really means 1/3.5, so f/3.5 is a larger number and opening than f/10. Since an f/10 aperture allows in less light than f/3.5, you are letting less light into the camera, effectively darkening everything, which also results in a darker background and the flecks of light on the glass getting darker to the point of disappearing. The problem is caused by the lights being positioned so they reflect off the glass dust and back into the camera, and the lights shine on the background when you don't want them to. A more effective solution will be a different light position-I suspect coming from your sides and/or from above, while not shining directly on the glass. This will allow a wider aperture (such as f/3.5), which lets more light into the camera lens, so your lights can be less bright. Angling the lights this way can make them hit the background less, too, darkening it. If you need to further control where the light goes, try this test: hold up a piece of cardboard next to the side of your light, blocking light from going toward the background and/or glass, but still allowing the light to shine on you. This will inform you of ways you can block/direct your light to where you want it, and where you don't. Cool set up. I may have to give this a try.

@@dwheywood I did adjust the lighting setup after, but at the time of making this video I couldn't because the lights I was using were too dim. I upgraded to some nicer Aputures (thanks to Aputure for donating them) and that's allowed me to move them farther away and to the side but also with much more light. This was filmed probably a few weeks before I changed my whole setup. I also got a better backdrop that's black paper. You can see some of the improvement in my latest "Korean FAQ" episodes, and I also filmed some more after those (coming after a few months) which got it a bit better and I was able to bring the F stop a bit lower for a better image.

​@@mogat035 Not super familiar with the G85, but I know its autofocus is not very good. Not an issue if you you don't need it to ever change focus, but a big issue if you do need it to change focus. If not using autofocus, set the focus to manual, and have someone focus it on you, and then it stays focused on that point. I would guess, but do not know for sure, that this would work fine, that is, having the focus fixed on you behind the lightboard. Would take experimenting, or ask someone who has filmed themselves using a lightboard if they use autofocus or not. The G85 isn't super great in low light, so you'd need some decent light brightness -and they do *not* have to be "photo" lights. Lots of considerations in picking a camera and lens. Too much to cover in this space, but those are the first two considerations that come to mind. If you determine that autofocus is needed, the lens choice matters for that too, as some lenses don't autofocus as well as others. Ah, camera gear, so many factors to consider. Good luck!

No interest in learning Korean but this is the best video I’ve found so far about making a light board setup! Bravo 🙏🏻😊

Lol yay i've always wondered how you do your faq videos. Its like super puzzling! But today i got the answer and i can sleep well for the rest of my life 🤣🤣🤣 thank you for your hard work!

Wow that used to really confuse me and i was like omg how can he write on nothing? Omg how can he write backwards? I had so many weird thoughts while trying to figure out what that was 😂😂😂

The light board is definitely a great idea for these types of videos, both for the viewer and the teacher. Cool vid!

I use both channels, but for different reasons. In learning languages, I minimize the study of grammar, learn sentences that I can use, and read either simple materials or books that seem interesting. When I start, I have been using Glossika for the sentences. As I begin to notice patterns, I turn to Billy’s site for explanations. I would say that he has a gift for good, concise explanation of basic matters. Sometimes, I just go down the list of his grammar videos and read whatever looks interesting. For reading I use LingQ. I have gotten pretty adept at importing what interests me. TTMIK has a wealth of material with audio that I can import. And their readers are some of the best. They have materials read slowly, and at normal speed. There are monologues, structured dialogues, and discussions between people. I have found helpful material on Korea Class 101, but very little in comparison to Billy’s and TTMIK.

to film like that, mirror the footage and edit it, is actually a clever idea. you could technically use an ipad and screenrecord it. but i find, as fancy as an iPad is, when you write on a board it's much more clearer, if that makes sense. it gives you kinda like a school vibe, which i prefer, but the handwriting is more accurate as well.

I like it my bro....

Thanks for the video! It seems as the the main problem I've heard with using light boards is that you can get reflections in the glass showing up. Will buying a better quality glass get rid of these reflections? If so, do you know of any better quality classes than plexiglass? Any input would be appreciated. Thanks!

@GoBillyKorean

3 жыл бұрын

No, the reflections are a part of how it works. Getting rid of reflections has to do completely with your light sources. Typically if you want to remove the tiny scratches though, you'd use actual low iron glass (Starphire glass is a good type) and not plexiglass. But plexiglass doesn't make any more reflections than actual glass. To remove reflections, position your lights more carefully, and don't have any sort of light (even small) in front of the board if possible.
