Acess phone camera with a button (HTML) : I'm developing a application that needs to acess the phone camera. I'm currently using the Ratchet Framework but that's not really relevant here.

I have a button that needs to open the camera onCLick. I know that to acess the camera we need this: 

    <input type="file" accept="image/*" onchange="updatePhoto(event);"></input>

And my button is like this:

    <button class="btn btn-positive btn-block"> Choose photo </button>

I tried putting the input to acess the camera inside the button but it doesn't make the ugly "Choose photo" disapear making it look silly. I just need to replace the standard "Choose photo" that appears when we put only the first input and replace it with the button to look better.
