The Minimum Resolution for Quality Images

If you have ever taken a picture with a digital camera, you may have noticed that the quality of the pictures that your camera produces differs depending on the size that you print them out at. Because of this, you must be very careful to always print your pictures out at a size that will present you with the best possible quality of images.
Many people submit the photos that they have taken with their digital cameras to professional printers, only to get poor prints back. They are quick to blame the printer, but the reason why the print is of such poor quality is because the resolution was too low for the size of the image.
In order to make sure that you get the best quality of images possible, there are a few things that you should take into consideration: the number of pixels that are in the photo, what resolution the photos should be printed at, and what the best print possible under these circumstances is.
In order to determine how many pixels are in your photo, you will have to look at the settings of your camera. For an example, the typical 5 mega pixel camera has a 1944 x 2592 pixel count. The lowest recommended resolution is 240 ppi, or pixels per inch. Divide the pixels per inch into the total pixel count of your photo and you will get the maximum size in inches that your pictures should be printed at. Continuing the previous example, a 5 mega pixel camera with a 240 ppi should be printed at a size of 8.1 x 10.8. Whenever you try to print a picture at a size that is larger than the pixel count allows for, you are going to get a blurred and pixilated image.
