Memory cards are one thing that all digital cameras have in common. If you think about it, nothing happens if your photos don't get onto the card, and nothing happens if you can't copy them from the card to your computer.
As Chris Lee from pal2tech points out in this video, your memory card can be the single most important component of your photography gear. Your reputation can revolve around how you manage that little piece of plastic.
Lee starts by explaining how you should label your cards so that you don't mix them up, especially if you're using multiple cameras. I've used this technique for years to identify cards just in case I think I might have a problem with one. Labeling your cards also makes it much easier to ensure that the new card you are putting in the camera is empty when you're changing cards.
Lee points out that you should always format a card in the camera that will be using it. I'll also add that I make it a habit to always format cards ahead of time. Formatting a card at the last second during a shoot is the quickest way to accidentally delete photos that you haven't transferred yet.
Although you should never delete photos in-camera, Lee also shows how to recover photos that you may have accidentally deleted. This is a topic that is often debated, but I only delete photos in-camera if they are obviously really bad, but most of the time, I wait until I get them on the computer.
