You'd be surprised, very very surprised, when asking someone to take a "good photo" they return with utter crap. One of the "thought crimes" in our society is people thinking they can take a good photo - most can't, even if their life depended upon it. It is actually shocking, because most people, seeing professional photography all the time, just assume they can shoot professional quality - until they try.

This works better if the interns are professional photographers.

So hire interns with a photography background? If they can build a rechargeable device which is capable of taking high-resolution photos without outside assistance they are more than capable, as a business, of figuring out the challenge of hiring the right people to support their engineering efforts.

Edit: Or better yet, hire a professional photographer when you want to showcase the output of your high-end digital cameras.

Isn’t it the whole point of smartphone cameras that you don’t need to be a professional photographer to take good pictures?

The whole point of a smartphone camera is that you don't have to carry a separate device. Easy to use cameras existed long before them. And even with a smartphonesmartphonecamera, I don't think skill is useless.
