Do you have an efficient way of keeping track of which batteries or memory cards are fresh and ready to use? Flickr user Damon Hair uses Post-it Flags to tag charged batteries and formatted memory cards, letting him quickly swap out used ones when shooting without having to check them one at a time. For an even cheaper solution, you can try wrapping a small rubber band around them instead.
