How I Make a Lightboard | Billy Backstage 

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.

@@dwheywood that’s an awesome explanation… I want to buy this camera (lumix g85 win the 12-60mm power O.I.S lens).. what do you Think???, is a good purchase for my incipient ligthboard project??

​@@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!

Real CTF I think TTMIK's channel works great if you already use their learning material online or their books, while Billy offers clearer explanations as for grammar and I generally prefer his style. Just my opinion though! 😂

@@giorgioc3402 yep I used ttmik learning materials online. Objectively speaking, both are good! but I personally prefer billys style.

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.

I like both Billy and TTMIK. I bought TTMIK's materials and then listen to Billy. TTMIK's books help me to practice while Billy helps me to understand. Its great to combine both 😍

Romaji RIGHT. I was thrilled!

I use a lav mic for these, and it's under my shirt taped to my skin and the shirt, and wrapped up to avoid any rustling noise. Positioning is important too. It's also a good lav mic.

@@GoBillyKorean Thanks for that. Does your recording device help with the sound quality or is a great lav mic the way to go?

Both are important, but modern recording devices should mostly be decent enough if your lav is good. These days there are a lot of budget options that work well. Until last year I used a Zoom recorder which I have linked in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FngFfeuLMt8.html Although for that video I had the audio levels set too high by accident.

Don't spray directly on the board. Spray on the cloth, and then after wiping with the damp cloth switch over to the other more dry side of the cloth and wipe it clean.

All of the equipment I used for this video is in the description below :) That's the lens I used for this video. The camera settings will depend completely on your actual room and the lights you use.

I used 1/4 inch, so 8mm is fine. But you don't want to use normal glass, because it will actually look a bit green on camera (because of the iron inside). If you use glass, it has to be low-iron glass (such as Starphire), but it's more expensive.

@@GoBillyKorean yes I am going to use low iron ultra clear glass. Just want to know 8mm is sufficient . I got answer from you now. Thank you so much

@@GoBillyKorean Love this recursion LOL

I just used plastic 6" spring clamps, but I think C clamps would get the job done even better.

@@GoBillyKorean I got C clamps because I saw a year ago Elisa Valkyria uses it in her lightboard. But I've seen in another videos that lightboard can be unstable and then I saw that u solved that with the wood tables. The C-clamps would work better even with the tables you use to make it stable? Or the spring clamps with the tables do the job better?. Thanks for answering.

@@gad2302 I've never tried C clamps with my setup. I just think they'd work the same as spring clamps, but maybe a bit stronger.

@@GoBillyKorean ok ok. I will let u know how it goes. Thank u so much. 🤗

These are just cheap 6 inch clamps made of plastic. I'm sure any clamp would work.

@@GoBillyKorean Thank u very much for the quick answer

The exact acrylic sheet I used is in the video description box.

All of the links I used are in the video description :)

There's a link in the description.

The one I used is in the description. I wouldn't recommend using anything thinner because it won't stand up by itself.

All of the items I used are in the description :)

I only put the LEDs on the bottom of the glass. If the LED is larger, it's probably okay, but I don't know - you might get extra light on to your hands as you're writing.

Learn Korean with GO! Billy Korean Thank You 😃

Make sure you're wiping it with a microfiber cloth. Other materials won't clean it perfectly. It also attracts dust easily so you'll want to wipe it when it's sitting somewhere for more than a few hours. Scratches shouldn't show, and if you have scratches those are just defects in the material. I've ordered two Plexiglas sheets and none of them have had scratches, but both had a few tiny tiny dots that don't show up on camera. You also don't need to have the LED around all four sides, since just a little bit of light is enough :)

@@GoBillyKorean Great advice. Thanks!

To prevent reflections you need to have the entire room dark in front of the Plexiglass. There can be light only behind it where you are. So turn off all lights and block any windows as much as possible. Or you can try filming at night time.

@@GoBillyKorean Thank you! I'll try it tonight.

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.

@@GoBillyKorean Thanks!

It's under my shirt.

Yes but grease pens won't look nearly as nice as markers.

It's the link for the acrylic sheet in the description :)

@@GoBillyKorean OK, stupid me, I didn't click to expand the description. Thanks!

They're neon, so it shows up better.

You can use Instagram to do a live stream. I even made a mirror filter you can find, which will flip the image :)

Mine only covers the bottom.

you'll probably be able to tell the difference between LONG before you're even intermediate level. I don't need to understand the language to tell them apart. you just need a bit of exposure to the sounds at a time when you know what the language is. For example, I've been to Japan, heard a lot of Japanese, and I'm familiar with the staccato way they speak plus often use a word that sounds like. sergeant saying "hi" and often they have words that end in a syllable "des"... I *think* the "hi" means "yes" and I have absolutely no idea what des means but I find Japanese really easy to identify. Similarly, the spattering of english and spanish and frequent use of "po" helps me know Filipino. Vietnamese have these cute diphthong vowel sounds that almost sound like the round echo of a water drops falling into a pool ...the *sound* of their language is really distinct. This is just a few examples and I could give more. I don't speak any of those languages, not even a little bit

Sure, but that would be very difficult to get the angle correct so the camera is not also visible.

@@GoBillyKorean try it . it works and you can go live no post production. you will get it right after few trails then its a fixed position every time. thanks for video .

No, regular glass will look greenish color. You want to use plexiglass, or low-iron glass. Check the video description to see what I used.

In the video I talk about how you should wipe it, and what to use. The lights can be anywhere that doesn't reflect back into the camera lens (usually the sides of the glass).

No, regular glass will look a bit green on camera. If you don't mind that, it's fine.
