HTML media capture is superb. I have successfully used it in production, and I was surprised by how simple it was and how well it worked. I learned about it from here[0].
It's cool because if you have an app that requires users uploading pictures, you just need an HTML <form>, an <input> with `capture`, and a few lines of code in the backend. I thought I would need to do some JavaScript gymnastics, and it ended up taking just an afternoon to design, develop, and deploy.
