I want to sign camera lenses

There may be people you have never seen before. I want you to take a look at the amount that comes up when you search "tennis camera sign".
Did you notice the coolness of it? It seems that recently, even other sports like baseball are doing this camera lens signing.
I've never played tennis, and I can't even serve the ball above my head, I just want to sign like that.
It seems like on the realy thing, they're signing on a camera lens film.
If that's the case, I'm pretty sure I can make some kind of plastic board, fix it to the front of my camera lens, and get signing done that way.

Let's get those materials and build it right away.

And just like that, it's all finished! How's that?

I was able to fix the camera inside the acrylic board.

If you use 1/4 inch screws, it'll work with the holes in the camera.

I took it to a tennis court to give it a try.

You could say the dawn colosseum next to it is, just like the Koshien for baseball, or the national pitch for soccer, the holy place for tennis in Japan.
I went to this kind of place purely for getting instant signatures.

There was a group of what I thought were high school students playing on the court. Ah youth.
Meanwhile, me without my racket, made my preparations on the outside edge of the court. So cold.
OK! Let's get those signatures without delay.

I couldn't see it at all. It's not focusing on it at all.
My heart and body were chilled to the core, and I returned home crying. Time to remake it.

Anyhow, the board was too close to the lens. Let's make it a bit further out.

I made the board giant sized, and it was pretty heavy. Now my hands are tired.

Before, I was using a black pen to sign, but it seems that was the wrong idea as well.
If you have a look at the tennis stars on TV when they do it, they just use a highlighter.
I thought it looked pretty colorful, but when I tried it myself, I understood. It doesn't really capture when you use black.
I bought thick Posca highlighters, so let's give it a try with these.

I went to try it out at a tennis court in a park in the neighbourhood.
Let's try and do it right this time. A moment of nervousness.

That went great, and it's so easy to see right!?
I'm writting with cling wrap over the top of the board.
And thanks to that, I can do it as much as I like. Even if there is a bit of twisting and lining in the wrap.

I'm so happy I was able to do it just like you see on TV.
Even if I can't play tennis, at least I can't take photos like a winner.

It's still cold though.
Of course on the day of my photography a big cold wave had to hit, so cold that I could only ask "Why?" out loud. Asking questions to the weather without thinking. It was super cold, so I went to a cafe and ordered a cafe au lait.

I'm sure I could just upload these photos to instagram as is, but just hold on a second.

With this apparatus, impressions can be put into photos.
It's just like photo booth scrawl, right? I feel like I want to build a market for this function on selfie sticks.
