OMG! Either put a lens or a cap on that thing. Just leaving the sensor out in the open?? I thought we all agreed that BBFS is a very, very bad idea.
(I joke, but really, close that hole up. Static electricity and your Nikon's sensor is charged as fuck, sucking up all the micro-dust in the room. I'd go bare back before I did this to my cameras). Jus saying.... [professional photographer btw]
Thank you Jack, I realized my mistake 5 days ago. Total newbie photographer here, if you would like to offer more advice and tips, I'd truly appreciate it.
