Digital Photography Tip Number 14....Carry Extra Memory Cards and Batteries
Tip #14) Carry Extra Batteries And Memory Cards.... You should always carry an extra battery and memory card with you when you are out taking photographs. Nothing is worse than having a great photo opportunity and your camera or flash battery goes dead, or your memory card is full. It doesn't cost that much to have a backup, and it will save you a lot of trouble.
Great Deals On Batteries And Memory Cards, Etc!
Most external flashes/strobes use AA batteries and I think it is best to have rechargeables. I use Energizer Nickel Metal Hydrid, but there are a lot of other good rechargeable batteries out there. Also make sure the charger can charge them back up fairly quickly like, a few hours or less, and not 16 hours like one charger I have. Very quick chargers like Energizers 15 minute charger are great, but I heard the batteries don't last as long using them. I have some batteries from 2005 and I think they are about done, they don't hold a charge anymore.
Also it is smart to have a voltage inverter in your car, that inverts your cars 12 volt DC voltage into 110 volts AC, so you can charge your batteries while you are driving. Or you can probably buy a charger made to plug into your cars 12 volt DC outlet.
If you have a fast camera, like one that can take 5 FPS or more, you can take so many photos in such a short time, and if you are shooting for a few hours, you will be eating up your memory card space very fast. Especially with a camera that can take 11 frames per second, you really need lot's of memory card space and computer space for that matter. I wouldn't take less photos though, just because you are worried about using too much space, because then you will miss some great action shots. They are always coming out with bigger memory cards and hard drives and the prices are reasonable, so I wouldn't worry about it.
Memory cards are getting cheaper and cheaper and adding more and more storage space on them, so if you find yourself running out of space too quickly, don't be so cheap, go buy a new larger faster memory card. It helps to buy faster memory cards also, then they will save quicker and preview quicker on your camera. Memory cards are coming in sizes up to 16GB as of this writing, but I still think it is safer to have a few memory cards just incase something goes wrong or is damaged with your main memory card.
Always store your memory cards in the little plastic boxes that they come in, and batteries in the cases/covers that they come in, so they don't get dirty or wet. CompactFlash memory cards have tiny little holes in one end and it wouldn't be good to get dirt or dust or water in them holes, not good at all. It could ruin the memory card or damage your camera if you try pushing it into your camera when there is dirt in some of the holes. If you just leave your batteries laying around without its cover, the battery contacts could short together while touching something and cause a spark and some damage to itself and surrounding items.
So now get out there and capture some great photography, and get some good exercise, fresh air and see some great scenery at the same time!!
