So, I just got done with a newborn in home photo shoot. I was actually just finishing up my last shot and all of a sudden my camera wouldn't work and it said "CF Error" ALL OF THE SHOTS I HAD JUST SPENT TWO HOURS GETTING WERE GONE! Ugh, I had to inform them that we had to redo everything. I felt so unprofessional and crappy I talked to my Dad about it since he's pretty good with computers and electronics, and he said that it sounded like I might be having a problem with static charges. He asked if I had walked on a lot of carpet and set my camera down during the shoot (which I did). He suggested that I get an electrostatic discharge kit for myself and my camera. Apparently the dry conditions here in Colorado make this problem worse. What I want to know is if his theory has any validity. I had formatted my card before I started so that couldn't have been the problem. I'm really upset that this happened. (At least it wasn't at a wedding, but I have one coming up soon and now I'm really stressed out that this might happen again). Can anyone give me advice about how to prevent it from happening again? Should I get the electrostatic discharge kit? Help!
