My roommate and I bird together frequently. We share a computer and store our photos in Picasa. She uses a Canon SX50, and I use a Canon SX60. The pictures are all numbered using Canon's IMG_xxxx format. Our pictures are stored in folders by date, and we can tell whose photos are whose based on the camera model identifier in the metadata (under properties in Picasa). I want to replace my SX60 with an SX50 but am concerned that we won't be able to easily tell our pictures apart. We don't want to manually rename files. Is there a way to number the files in one camera differently than the IMG_xxxx naming convention, or is there some other way to add an identifier to the metadata to distinguish our photos? Thanks for any ideas you can offer.

Love these! What equipment did you use?

Looks like a female red-winged black bird to me.

Very nice photos of this pretty little bird. Better than I've been able to get with my Panasonic FZ1000. What bridge camera did you use?

Great photos! Did you visit any particular place where you were able to see a lot of birds?
