Have you edited a photograph on your computer and when you went to print it, it was just a tiny image on the page? Have you ever emailed a digital photo to your mother but the image file size was so big that her inbox rejected your attachment? Digital Resolution Pixels are the name of the tiny dots that make up an image and resolution is the quantity of how many pixels fit into one inch. Our televisions, computer screens and even digital cameras are full of pixels - thousands upon thousands of them all jam-packed together so closely it tricks the human brain into thinking these tiny dots are a smooth image. The higher the pixel count within an image, the smoother the image looks. On the other hand, if the pixel count is too low, the image quality degrades. When the pixel count is so low you can see the jaggy edges, you've got a pixelated image. Digital camera images have a high pixel count whereas nearly all home computer monitors have a low pixel count, in general under 100 pixels in an inch. Displaying high resolution images on a low resolution device results in an image that appears much bigger on the computer screen. Digital cameras acquire images at high resolution to allow photographic quality prints. But sending this large image file by e-mail will take megabytes of data and many e-mail users will disallow it. Image Resampling The key is resampling the image which is geek speak for altering the resolution. Decreasing the number of pixels will make the image appear normal on a computer monitor. And this will allow you to e-mail Mom with the latest family photos from your recent vacation. But after decreasing the resolution of the image, don't think that you will still get a good photograph any longer since you've taken out so many pixels. So here is the bottom line. Digital images meant for printing need to be at a high resolution but images displayed on a computer screen need only a low resolution. If you feel like doing both printing and sharing of your digital images, make a copy of your original digital image for experimenting with. Besides allowing for both printing and viewing images correctly, this is also a well recommended backup plan for all of your digital photos.
