Most photographers are always on. I am no different, even when I am not holding a camera and actively shooting, I am aware of the light, of compositions, of what would be photo worthy.
I can not recount the number of times I have been out running errands and a beam of light inspired me. So I am composing shots and using the camera on me— my cell phone— to make a little bit of art. Its a rare day when I see something on a whim that my camera is with me.
But I find the best camera is the phone you have and yes cell phones have come a very long way.
Never stop seeing. Never Stop shooting!
Use the gear you have — your eyes, heart, and phone!
