Depending on the camera, or scanner, used to create the digital image there is one thing that remains important, the picture quality. There are two important factors to remember when dealing with the picture quality of a image. If you are planning to print the image then you will want a high resolution image. If you just want to view the image on your computer, or put it on a web site, then you will want a smaller resolution or the image will appear to be very big. Also, if you are dealing with images that are just going to be viewed on a computer screen you will want the image to be in RGB (Red, Green, Blue) color, which will allow the image to look better (all images taken from a digital camera will already be in RGB color).
|Here are two digital photos. This shows how a picture with a higher resolution looks larger on a computer screen, compared to a picture with a smaller resolution. Because the pictures would be too big to put on this page I am showing them at 25% their normal size.|
|As you can see, the 1280x960 image appears to be much larger then the 640x480 image. A smaller resolution image has a smaller file size compared to a higher resolution image. Although these images appear to be much different in size if I printed them both in a photo editing program, like Adobe Photoshop, they would be the same size on paper. Why? Because the higher resolution image prints out having more detail then a lower resolution image. Now you know how the resolution of a digital image is important.|
