Photo Backupの Photo Backup 1st Edition の目次

According to market researcher InfoTrends, by the end of this year picture takers around the world will clock up 1.3 trillion digital image files. And Canon Australia says that a full two-thirds of photographers it surveyed have lost digital image files due to ‘the damage or failure of physical technology’. InfoTrends actually refers to digital image files as ‘photos’. But are they there yet? Is a series of electronic 1s and 0s locked up in a file on a computer or memory card the same as something you can hold in your hands and see with your own eyes? The largest number of ‘real’ photos taken with film cameras was in 1999, when something like 80 billion exposures were made. With rolls of film having only 24 or 36 exposures,…

Until now we’ve limited our survey of image storage alternatives to digital image files, but film and photographic prints must be digitised before they can be stored and added to your 21st century picture collection. What priority should the job have? If the prints are in acid-free archival albums, they are arguably more secure than any files you have in digital form. On the other hand, colour prints will deteriorate over time, and having just one copy of a valuable family image means it can’t be shared, and is vulnerable to fire and flood. A home office inkjet printer/scanner will do the job, but it’s a slow and tedious bit of work. A good consumer level dedicated scanner from Canon or Epson will cost $100 to $200 and do a…

So you’ve started to exercise discipline in the number of photos you take, and you have been deleting sub-standard or surplus image files in-camera. You’ve decided upon a backup system and there it sits, shiny and new on the desktop. All that remains is to actually bring an image collection together in a form that is secure, long lasting and will allow you to find and share specific images easily. We strongly advise that first of all you do a full, separate backup of everything on your hard drive before you try any of the routines explained in this book. After completing your separate full drive backup, it’s worthwhile checking your collection for duplicates prior to building your photo archive. If you’ve ever opened a file to work on it…

As has been mentioned several times through this guide, printing photos is a great way of storing them safely. Some experts say it’s the definitive storage strategy, and printed photos have the added benefit of being viewable ‘natively’ by the human eye. For over a century, and until the last few years, silver halide (AgX) photographic printing stood alone. It was the only alternative. Today, while there are fewer photos being printed, it’s not for lack of alternatives: home printing or retail; silver halide, inkjet, dye sub, digital press or colour laser printing; paper, canvas or metallic; prints or photo books. If you choose a photo quality home printer, use the recommended inks and good quality paper, you can print photographs at home which both look great and have projected…

The most common next step in the life of digital image files is transferral to a computer hard disk. And this is where most (camera) images remain, and also where they are most vulnerable. Most desktop computers still use hard disk drives (HDDs) for data storage, while laptops are moving over to more compact SSDs (Solid State Drives – another form of flash storage technology). SSDs are a close relative of the USB drive or thumb drive, which in turn are part of the flash memory family that SD and CompactFlash cards belong to. The hard drive contains a platter with a thin magnetic coating, spinning at thousands of revolutions per minute. To transfer your digital image file, a ‘head’ moves over the platter, writing 0’s and 1’s as tiny…

Physical backup Once you have created your new master folder structure and are satisfied that it will work for you, it’s time to back it up to external media. The golden rule is to have three copies of your digital files, with one off site so that a calamity at home won’t mean the end of your photo collection. The remaining two should be local but on different storage devices. So, for instance, if you stored images on your computer; to an external hard drive; and to a separate drive offsite kept exclusively for your media collection; or to Google Photos or another Cloud storage service, that would fulfill the ‘3-2-1’ requirements. Regardless of your image collection, you should also be running a full backup of your PC to an…
