• • • • • Digital photo quality is measured in megapixels. A pixel is a tiny dot of color, and when many pixels are combined an image is composed: 1 megapixel equals 1 million pixels.
In 1999, when the digital camera industry began to boom, the standard digital camera took photos made up of between 1 and 2 megapixels. Today, most newly released digital cameras take photographs with 10 megapixels or more. If your camera is capable of taking photos of at least 4 megapixels, then you can determine the number of megapixels in a specific image using a simple calculation. Video of the Day.
Determining the number of megapixels in a digital photo is simple. Step Determine the length and width of the digital photograph in terms of pixels.
15 Amazing Examples Of Gigapixel Panorama Photography - The following 'Gigapixel Images' are ultra high resolution images created by shooting hundreds of photos (or even thousands) and stitching them together to make a larger single image with greatly increased resolution. Photography and Camera News, Reviews, and Inspiration. 365-Gigapixel Panorama of Mont Blanc Becomes the World’s Largest Photo.
You may find this information by right-clicking the image and selecting the 'Get Info' box or by examining the photograph in a photography software program. As an example, let's consider a photograph that is 1,000 pixels in length and 2,000 pixels in height. Step Multiply the length of the photograph in pixels by the height of the photograph in pixels.
In the example, you would multiply 1,000 by 2,000. Step Consider the product of your calculation. If your product is between 4 million and 5 million pixels, then your photo is considered to be 4 megapixels. If the result of your calculation is less than 4 million pixels, than your photo is smaller than 4 megapixels.
If the result is larger, your photo is larger than 4 megapixels. In the example, the product is 2 million pixels or 2 megapixels, which is smaller than 4 megapixels.

Digital Photography Basics Digital photography offers speed, flexibility, and cost savings in acquiring, editing, sharing, presenting, and printing photographs. But it also requires the user to acquire a few basic skills in managing and editing the images. What is a Digital Photograph? A digital photograph is made up of thousands or millions of pixels (from ' picture elements'), which in simple terms are the tiny little squares of solid color or shades of gray that are the basic building blocks of a photograph. A 6 megapixel camera creates an image that is about 3000 pixels x 2000 pixels -- 6 million pixels (megapixels) total. A 3 megapixel camera with the same height-to-width ratio (that can vary a little) creates an image of about 2100 pixels by 1400 pixels, and so forth.
16 Megapixels Vs 20 Megapixels
As a general rule, the more pixels, the greater the detail, but the size of the image file on disk also increases exponentially. In each case, if you multiply inches by pixels, you get roughly 3000 x 2000, or 6 million pixels. The image file on your computer is exactly the same -- the difference is only in the way it is interpreted on paper. Saying that a digital photo has such-and-such a resolution has no meaning unless the print size is also specified. Minimum Standard for Pixel Dimensions: The HPO minimum standard for images for both survey and National Register nominations is a pixel dimension of 1950 x 1350. This creates a print of 6.5' x 4.5' at a resolution of 300 ppi (a 7 x 5 print with margins). A 3 megapixel camera should create an image of about 2100 x 1400 pixels, and this is why it is the minimum for survey and National Register work.
