I'm planning to bring three cameras with me on our upcoming trip to Paris: two digital cameras and a camcorder. In addition I will also have a battery charger and portable storage device. All of these come with dedicated electrical cords (A/C adapter, camera to computer connection,etc.). With a multitude of electrical cords in my camera case, things can get a little confusing. Using the wrong A/C adapter cord with the wrong equipment could result in disaster. I used to put a label on each accessory cord identifying which camera it is used for. However, I believe I have come up with a idea that results in instant identification for matching accessory cord to the correct camera.
I purchased some colored electrical tape at the local Home Depot. To each camera and portable storage device, I applied a different color 3/8" x 3/8" square of electrical tape. All the accessories that apply to each piece of equipment received the corresponding color tape. Now when I need to connect the battery charger to the A/C electrical cord, I just have to grab the cord with the matching color.
If you are a shutterbug, this idea may be helpful in preventing a potential disaster.
