Store images on a hard drive connected to your computer, and, as Ms. You also need to know that there’s no completely foolproof method to backing up your images.
Unfortunately, preserving the original photo isn’t the only issue you’ll face when backing up your images. That’s also why you want to carefully choose a backup solution, whether it’s online or an external hard drive. That’s because when you back up your photos, you want to be able to retrieve an image file that is as close to, if not identical to, the original photo you captured on your phone or digital camera. It’s why you might think you’ve backed up your image when uploading it to Facebook or other social media sites, but that’s not really the case.īut right now, most websites, including social media and even photo-printing sites, aren’t designed to truly store photos. However, it’s often difficult to visually detect if an image file has been altered, particularly on a smartphone’s small screen. It may digitally compress it, too, throwing out additional data important to image quality. When you post it, Facebook, in most instances, downsizes the resolution, or reduces the number of pixels to make it smaller. Now, say you upload that photo to Facebook. Since one million pixels is known as a megapixel, the resolution of your smartphone image is 12 megapixels. If an image you shot on your smartphone, say, is 4,000 pixels high by 3,000 pixels wide, it contains a total of 12 million pixels (the height multiplied by the width). Namely, image resolution.Įvery digital photo has a certain image resolution, which is the total number of pixels that make up a photo. Before I explain how to back up your photos, it’s useful to understand one important aspect of digital photos that relates to storing them properly.
