A question I am often asked by beginners in photography is how much memory do I need? The answer to this question will depend on a lot of factors. Let us consider all of the one by one.
1. The resolution of the camera: This is probably the most important factor that will determine the size of memory required. If you have a 2-3 MP camera (which is very unlikely unless you are using a phone camera as almost all digital cameras today are more than 5 MP resolution). If you are using a basic 5 MP camera I will advise you to use a 1 GB card. You can also use a 500MB card but the difference in cost between a 500 MB and 1 GB card is negligible and what’s the harm in using a higher memory, you will be able to store more photos. If however you are using a pro or semi pro DSLR, then you should consider a 4GB card as a standard.
2. The quality of the picture you intend to take: All cameras allow you to set the resolution of the picture it takes. Lower the resolution the higher the number of photos that you can store in your card but remember that lower resolution means poorer quality of photos.
3. How many photos do you want to take? Are you going for a long vacation with lot of photo ops? Then choose a card with higher memory. A 4 GB card is ideal for long vacations. Apart from this the size of the memory card you choose will also be guided by your proximity to a computer. Can to download your photos to a computer regularly. If yes, then you can manage with a card of smaller size, but if you do not have access to a computer then it is better to have a card with higher memory.
4. If you’re serious about photography always carry an extra card with you (I carry three cards each of 4 GB). Of course you will not need this kind of memory unless you are a serious photographer, but at least carry one extra card with you.
5. Today memory cards are very cheap and you will find cards with 16 GB of memory for as less as $100, so if you think that it will be good investment then you should consider buying a higher memory card, it will be very useful to you.
And finally a tip on storage of your cards: Keep your cards away from direct sunlight and dust. Also keep them away from moisture and strong magnetic fields. It is best to store your cards in the pouch given along with it.
