Why don't sharks bite photographers who shoot sharks at the bottom of the sea?

Why don't sharks bite photographers? There are many theories about why sharks attack humans. The most ridiculous thing is that the human silhouette looks like a seal from below, and sharks eat it. But humans still have many ways to stop sharks. For example, anti-shark agents, such as wearing orange diving suits, including life jackets and lifebuoys, are now in this color, also to prevent sharks.

But if you bleed, I'm afraid it's useless. Sharks will be crazy when they smell blood, and they can smell a little blood for miles away. So once you are injured and bleeding in the sea, you should get out of the water immediately, otherwise it is very dangerous!

I hope it helps you.
