are flash memory cards that digital cameras use today in our
(but also in video camcorders and phones) instead of film.
To take full advantage and avoid surprises (do not lose hundreds of photos to please anyone and one can too) here is some advice based on experience (even negative):
1 - Do not aim for maximum savings
We are certainly among those who advise the beginner to faint even with buying the latest model of memory, the bigger, the faster (only those who really need a lot of speed and many GB can do that), but it is better not to bet the maximum savings. A defective card can also happen by choosing a familiar brand, but is a less frequent event. Today there are cards on the market producers may never heard before surprises (there are some false copyright, so eyes open and buy only from reputable reseller).
2 - Test your memory before important pictures
We're going on a trip, or we plan a day of photo shoots that are particularly important: the worst thing we can do is buy a memory card to ' last moment, put it in your bag and try it for the first time ... the field.
flash memories are of course tested in production, and generally work for, but something can go wrong even after packaging, a speck of dust that has ruined a chip (the memory structure is very complex), electrostatic charge , mechanical damage and so on.
find among the makings of a damaged memory is really a nasty surprise, especially when we brought with us just that.
So, to avoid trouble, you should buy the card with a little 'ahead and try it before the trip, or day of shooting. Even a card "proven" may subsequently be damaged, but it is more difficult. Generally if there is a problem, this occurs immediately.
3 - Place the stock market more than a memory
One memory, large capacity, it may seem the easiest way (the card is in the car, do not have to worry about all those little memories that we can easily get lost in the bottom of the bag). But for the discourse made above (congenital or acquired) can detect a wrong choice. Better to have two or more memory cards: so you minimize the risks. If a memory is showing signs of malfunction, we can count on that / and reserve.
Besides buying more cards with less spare capacity, because the newly introduced models have always prohibitive prices.
4 - Avoid touching the memory card
It 'good to handle memory and avoid touching the contacts with your fingers.
5 - Never remove the memory from the machine during the writing Files
a suggestion may seem unnecessary, but it is not. Today digital cameras are equipped with a capacious memory buffer in the case of digital SLRs also very roomy. The machine is able to take several pictures in rapid sequence storing them in the buffer before transferring them to memory card. Which can take several seconds (depending on the write speed of memory). We must have patience and wait for it to complete before you remove the card, otherwise we run into problems.
For the same reason, especially with cameras and dated, we can also run into problems off the machine while it is flushing del buffer.
6 - Ricaricare la batteria prima che arrivi a fine corsa
Sfruttare la batteria della fotocamera fino all'ultima goccia può comportare problemi alla scheda di memoria. Infatti, non soltanto rischiamo di perdere l'ultima foto, ma anche di danneggiare il file system della scheda.
7 - Rimozione corretta della memoria
Se abbiamo trasferito le nostre foto dalla scheda di memoria al computer, attraverso un lettore di memorie, dobbiamo seguire la procedura corretta per la rimozione (Windows e Mac OSX hanno procedure diverse) altrimenti rischiamo di perdere dei dati e di danneggiare la shceda.
8 - Cancellare o Format the card?
After transferring photos from memory to our computer we have two options to delete the photos from the card. The first is, in fact, deleting ("erase all"), the other is the card format.
If we take the health of our memory card we have to do a favor now and then format it (several times a year, or more frequently if you use the camera often).
Formatting, which is made from the camera (just read the instruction manual to find out where the camera is naascosto command in the menu) for maximum compatibility-memory machine, ensures a better operation of the board and longer life. If we realize that we try to slow format. Most of the time the memory will continue to work beautifully.
If there are those who "fear" to format the card, there are some who do it every time you download photos. It 's a dangerous procedure? No, if you want you can format each time.
If formatting via camera is the best, does not always work. In this case you can try to format it with another camera, or using the computer.
9 - recovery of deleted photos
The idea of \u200b\u200bformatting the card to someone afraid of, "lose the picture cncellate by mistake"? Given that it is okay to delete, or format, the card only after you are sure you transfer photos to your computer, or deletion, formatting or impede the recovery of the photo.
Some memory cards are sold with software that allows the recovery of deleted photos groped by mistake. Otherwise you need a specific software, such as the excellent PhotoRescue (www.datarescue.com/photorescue/).
10 - Watch out for dust and weather
Some memory cards are designed to operate properly in extreme conditions (the temperature data are operating in the package), the other hand, may suffer frost and hot weather. In general, all flash memories suffer from moisture, dust, sand and magnetic fields.
If placed in a plastic sleeve dedicated to the memory is protected and lasts longer.
