If you were to lose your camera today, would anyone who found it be able to get in touch with you? If not, it might be a good idea to put a couple “digital dog tags” on your camera’s memory card. First, add a photo with your contact information onto the card so that anyone looking through the photos on the camera will come across it. Next, add a series of text documents to the root directory of your memory card (the first directory that appears when you access the card on a computer). Give these files names that both attract attention and contain your contact info. Open up these text documents and add your full contact details. This way, anyone who opens up your card on a computer will (hopefully) see your info as well.
These tips are especially useful if you’re traveling with your camera, since you might not be clearing the data off your card very frequently and may have a higher chance of losing your camera.
