Photoshop Tutorials For Beginners - Photoshop Editing

Ever been disappointed by a tiny printed image after editing a picture from your digital 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?

Pixel Dimensions

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

Our televisions, computer screens and even digital photographs are full of pixels - thousands and 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 in an image, the better the photo looks. On the other hand, if the number of pixels is too low, the image quality suffers. A pixelated image results when the pixel count is so low, you can see the jagged edges.

Digital camera images have a high pixel count whereas nearly all home computer screens have a low pixel count, in general under 100 pixels in an inch. Displaying the former on the latter results in an image that appears much larger 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 reject it.

Adjust Resolution

The solution is resampling the image which is computer speak for changing the resolution. Decreasing the number of pixels makes 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 photo any longer since you've taken out too many pixels.

So the sum and substance to remember is this: Digital images that will be printed need to be at a high resolution whereas images displayed on a computer display need only a low resolution.

If you need to do both of the above, make a copy of your original digital image for experimenting with. Besides preparing for both printing and viewing images correctly, this is also a well recommended backup plan for all of your digital photographs.
