If you don' t use the card right after doing that, there is software that will recover the photos. It works pretty well. I've recovered a lot of photos for a lot of people.
I ended up with losing a whole days shooting in Yosemite and was devastated...until I used some recovery software and got most of them back...in fact, even tho I format the card before each use, but rarely fill them, there were images on there from several different shoots that hadn't been written over.
Google image recovery and check them out...many are free.
