Ok, So i deleted an image by mistake...during the wedding. I reshot the image...but i still prefer the one i deleted. What do you suggest is the most efficient way(software) to rescue it? I am on a mac and use Mountain Lion.
It's a little clunky, but it's free. I just used it, and compared it to a few trial versions of other recovery software, and it recovered everything that they did and a few more...
Good luck. I never delete in-camera for this very reason. I've got plenty of space and no reason not to wait to remove files from the batch in Lightroom.
