I'm Eric . It's a pleasure to meet you. And I know you know a lot about photography. Yes. Um, so you understand that with a camera lens, uh, it's able to open up. It's called the, the aperture. Exactly. What you may not know or may not have seen before is one of these. This is an old Chinese coin and the hole- It's extremely small. Actually, if you don't mind opening your index finger. If I leave it there, you'll be able to see that the hole is really smaller than the finger.
Je suis Eric. Enchanté. Vous êtes un expert en photo. Oui. Vous savez, un objectif d'appareil photo peut s'ouvrir. C'est ce qu'on appelle l'ouverture, exactement. Ce que vous ne savez ou n'avez jamais vu, c'est ceci. C'est une ancienne pièce de monnaie chinoise et le trou est très petit. Il est extrêmement petit. D'ailleurs, si vous voulez bien tendre votre doigt index. Si je la pose là, vous verrez que le trou est vraiment plus petit que le doigt.
