Digital Camera

I try to be on:
Parks, plazas, and proms
Wherever you may frequent.

Press my buttons
And you’re mine
As long as you want.

But you
In shades of gray
Are hardly black and white:

Unclear,
Out of context,
A facade.

So hit another button:
Step a little closer
Or disappear.

There are more like you;
But who’s in focus
When my energy runs out?
