[Harry Potter] Could a camera with a timer and a flash setting capture a boggart's true form?

Nobody's ever seen a boggart's true form because it takes the form of your worst fear, but what if it were trapped in a cupboard with a camera and no people and then the camera took a photo?

I like to think that it maintains its most recent form until it has reason to change. Mad Eye might have just seen some random thing that would never be in a cupboard and knew it was a Bogart because why would a clown be hiding in a cupboard? 

But that's just an assumption.
