Photoshop Tutorials For Beginners - Viewing Digital Camera Images

Ever been disappointed by a tiny printed image after editing a digital image from your camera ? 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 Camera Resolution

Pixels are the name of the tiny dots that make up an image and resolution is a measurement of how many pixels fit into one inch.

Our TVs, 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 it is a smooth, unbroken picture.

The more pixels in an image, the smoother the photo looks. On the contrary, if the pixel count is too low, the image quality degrades. When the pixel count is so low you can see the jagged edges, you've got a pixelated image.

Photos taken by digital cameras have a high pixel count while most home computer displays have a low pixel count, generally under 100 pixels in an inch. Displaying high resolution images on a low resolution device results in an image that appears much bigger than the computer screen. Digital cameras acquire images at high resolution to facilitate photographic quality prints. But sending this large image file by e-mail will use megabytes of data and many e-mail users will refuse it.

Image Resampling

The answer is resampling the image which is geek speak for changing the resolution. Decreasing the number of pixels will make the image appear normal on a computer screen. And this will let you e-mail Mom with the hottest family photos from your recent vacation. But after decreasing the resolution of the image, don't think that you will still get a good print any longer since you've taken out too many pixels.

So here is the main point you should remember. Images that will be printed need to be at a high resolution but images displayed on a computer display 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 images.
