One of the biggest benefits of digital photography is that you can take as many pictures as you want at virtually no cost - associated with developing and printing or film to pay for the there's nothing to keep you shooting away to your heart's content.

And today's pcs come with such huge hard disk drives that it'll still take years unless you want to fill them up together with your digital photos. But there is a downside to keeping your own individually styled irreplaceable photos and memories of a computer's hard drive; let's say (or some would say when) it is going wrong, or is broken down through accident or burglary? You're left with nothing - particularly if, like most people, you print only a small proportion regarding your photos. With this in mind, here are a few suggestions for making sure your useful JPEGs are as safe as i can possibly be.

Backing up

By far the best strategy is to back up your complete digital photos. Virtually all modern PCs expends CDs, and you'll need to fit from around 100 to around a thousand images (depending on resolution) on one disk costing under 50p. If you really value your photos I suggest making two copies of CD you write, and storing one of the very copies somewhere safe - or perhaps somewhere separate from the computer itself.

In an ideal world you'd have one set of CDs at home and a second at work, but of course this might not be possible. If you take a lot of high resolution photos perhaps you may consider using DVD%2B/-R as an option to CD%2B/-R (DVDs hold around seven fold data than CDs). If you need access to your photos regularly, you might consider a large external hard drive (with a FireWire furthermore USB 2. 0 connection) to store them on (in addition to the Drive backup) - that way your computer fails you'll still acquire your images.

Other backup options

If you don't shoot tons of images you can back copies regarding your images using an the internet photo sharing site, most notably fotki., which offers free getting it for modest collections depends upon unlimited web storage through a small annual fee. Such sites also have the belief that you can access a guys images from any internet with web access, anywhere in the world, and many also offer catalog shopping printing of your ways. Of course storing your images on the internet is only really practical if you fast internet access at first so broadband is a distinct advantage. It's also worth selection with your ISP to check if they offer a at the same time free service.

The file format of image file has a suffix to indicate what type of expansion the file is - like this:

Image1. jpg or Consequently. Gif or Wedding. Tiff or otherwise not Windmill. bmp etc

In images, however, the files used are usually in jpg, tiff or otherwise not raw format. Unless you require altered your camera equipment, your camera will save your images as jpg (or jpeg), pronounced jaypeg.

JPEG files also have the advantage that they are opened and read by many popular software packages. But essentially the most important thing about JPEG does it look allows photos to become more 'compressed' - squashed down in order that they occupy much less space of this memory card or computer hard disk.

A typical 3 mega pixel digital photo contains around 9 Megabytes' worth of information. So if you will have a 64MB memory card you'd be checking out a maximum of seven shots prior to being full. However, JPEG uses some very clever maths to cut the file size to as young as 1/100th of its source size without reducing quantity pixels in the famous, thus allowing you to support many more pictures.

But there's been, inevitably, a downside. To build such space savings JPEG has to discard almost all of the information in the interesting photo. This is described as 'lossy' compression, (because something's lost). But it's nowhere close to bad as it may sound! JPEG offers the option to vary the level of compression, and the not more compression used, the less noticeable restricting quality is to the human being eye.

The problem is that when you open a jpeg and provides resave it, you take several of the image quality away along with it. Viewing without resaving is OK but so as to crop, rotate or edit the picture and resave it, you will burn image quality each that number.

It is best to support a separate copy out of the modified image and experiment on that and only make use of original images for vacation. However, there is an easier way of storing your very images (and edited ones) whilst retaining maximum image quality - but more this particular in another article (Editor permitting).
