Ok, so I guess I have been taking a lot of pictures!!LOL with both of my cameras and now I am running into a problem with the file numbers overlapping. I discovered it tonight when I saved one of my images from LR into the file where I store them for making into layouts. There was already one there! I suppose the problem would have shown up when I uploaded except one camera was saving a jpeg and the other was a CR2 file.
So what do you do to avoid conflict from two neck and neck cameras? Is there some naming convention that can be changed in the cameras?

Thanks for any advice.
