When we hear 'digital' we automatically tend to think of high quality. Digital sound does not degrade no matter how many times you play it. Digital images can be saved forever and will still print in its pristine form.

digital image
An image, whether displayed on a monitor, projected on a screen or printed on a sheet of paper, which has been created from a data file which contains colour information for all of the pixels which make up the image.
In digital image processing, a histogram is a graph representing the statistical frequency of the gray values or the color values in an image.
In digital image creation and workflow pixel resolution (dimensions in pixels) is the first and most important decision. 'What pixel resolution do we need to print to 8X10 inches at 300 ppi output resolution?

Tip 5: Digital images are not the same as film images.
Digital photos are not necessarily better or worse than film images. They're simply different.
Digital images are formed from tiny dots of color. The dots, usually many millions per image, are so small and close together they blend into the smooth continuous tones we're so familiar with from film.
Digital images can be prone to noise due to the visual effects of electronic errors of the camera's sensor.
Digital images are made up millions of pixels; tiny square or rectangular photosites that have a specific colour and brightness. A Megapixel (Mp) is the same as 1 million pixels so a 12 Mp image is made up of 12 million pixels.
Digital images often have brightness levels across the photo that are out of sync with the subject and composition. This causes problems for both the photographer and the viewer because brighter areas in a photo attract the viewer's eye.

Digital image files are' memory hogs'. A true 'megapixel' 24bit uncompressed colour image would take up 3MB of storage.
Digital images can be brightened and manipulated in a computer to adjust color and increase the contrast.
Digital images can take up lots of storage, so most are compressed in some way. Compression is usually a trade-off however between file size and quality.

Digital images separate color information into individual channels that represent the components such as Red, Green, and Blue (RGB). If viewed individually, the pixel information contained in the channel is a grayscale representation for that color.
Digital images are inherently soft due to the nature of pixels and how we perceive the images they collectively produce. Sharpening is a method of adjusting the contrast levels between adjacent pixels to give the appearance of a sharper image.
Digital images are made by displaying tiny dots on a (usually) rectilinear grid. Straight lines which go in either horizontal or vertical directions on this grid will always look fine, but diagonal lines can be a problem.
A digital image sensor has a native ISO. When you adjust the ISO setting, the sensor itself isn't changing; rather, the amplification is changing. This is fundamentally different from film.

gamma correction:
This is a process that makes pictures appear more accurately on a specific monitor via tone mapping.
But digital images can pile up in your computer just as their printed ancestors piled up in boxes in your closet.
All digital images have noise. Though an imperfect analogy, you can think of it as being like film grain. The lower the ISO setting, the lower the noise, just as lower ISO films have finer grain.
Does Digital Image Manipulation Affect the Value of Images?

With digital images, photographers have many options that can be used to enhance shadow and highlight detail.

From the moment you see an image through your camera's viewfinder to the final delivery on your computer screen or website, as a photographic print, or printed in a magazine, brochure or book.
When a digital image is displayed or printed at the correct size for the number of pixels it contains, it looks like a normal photograph. When enlarged too much (as is the eyehere), its square pixels begin to show.
Noise in digital images is most visible in uniform surfaces (such as blue skies and shadows) as monochromatic grain, similar to film grain (luminance noise) and/or as colored waves (color noise). As mentioned earlier, noise increases with temperature.
Pixel: A digital image is made up of small continuous tone spots called pixels. The word pixel is derived from the words Picture Element. In an RGB image (with a of 24) each pixel can be any one of 16.7 million colors/tones.
Although digital images make taking and looking at pictures easy, they will probably never replace the special nature of albums and physical prints.

A digital image created from rows and columns of dots called pixels, the more bits associated with each pixel, the higher the bit depth.
A conventional digital image has pixels which can be red, green, blue of any one of millions of other colors, so to generate such an image from the data output by the sensor, a significant amount of signal processing is required.
Zoom in on any digital image closely enough, and you'll notice it's made up of tiny little squares. These are pixels. Image quality is most often described in terms of how many pixels a photo has. A million pixels is equal to 1 megapixel (MP).
The Reality of Digital Image Capture
On the downside, there is considerable lag between when the shutter is released and when the image records, making capturing peak action often very frustrating.
