Setting Output Resolution to Print Big Pictures

To figure out the biggest size at which you can print your picture at a certain resolution, divide the number of pixels across by the resolution you want. The result gives you the largest print width you [more…]

Computer Monitor Resolution

Like digital cameras, computer monitors (and other display devices) create everything you see on-screen out of pixels. You typically can choose from several monitor settings, each of which results in a [more…]

Making the Connection Between Pixels and File Size

Each pixel in a digital photo adds to the size of the image file. If you pack your image with pixels, you have to deal with its huge file size. To keep your pixel count [more…]

How Many Pixels Are Enough in Your Digital Images?

Because printers and screen devices think about pixels differently, how many pixels you need depends on how you plan to use your digital picture. So, the answer to the pixel-number question is, “It depends [more…]

Resolution and a Picture’s Appearance and Quality

Before you print a digital photo, you specify an output resolution, which determines the number of pixels per inch (ppi) in the printed picture. Output resolution, also called image resolution or simply [more…]

Computer Printer Resolution

Printer resolution is measured in dots per inch (dpi). Printed images are made up of tiny dots of color, and how many dpi the printer can produce defines that printer’s resolution. The higher the resolution [more…]

The Different Types of Digital Camera Image Sensors

Two main types of sensors are used in digital cameras today: CCD (charge-coupled device) and CMOS (complementary metal-oxide semiconductor) imagers. Although each type of sensor uses different technology [more…]

Your Digital Camera Resolution Options

Camera resolution refers to the number of pixels that a camera can capture, and the resolution for you depends on how you plan to use your pictures. Do you want a resolution that suits pictures on your [more…]

The Components of a Digital Camera’s Image Sensor

All digital cameras’ image sensors are made up of the same components. These components help determine how your camera’s sensor records light and therefore how your image appears. Each sensor includes [more…]

Understanding Noise in a Digital Photo

Digital camera sensors have varying degrees of sensitivity to light. The more sensitive the sensor, the better it can capture images in low light levels — but a sensitive sensor also produces noise. [more…]
