Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure to photographic film. The captured images are digitized and stored as a computer file read for further digital processing, viewing digital publishing or printing.”

So digital photography is merely the digital process by which an image is captured. But the elements of photography and achieving exposure are the same. A digital camera still relies on shutter speed, aperture, and ISO to create an exposure, the same as in film photography.

The advantages of digital photography
Wander through the camera aisle of any big box store and the shelves will be loaded digital cameras and memory cards. If you’re looking for a film camera or film, you’ll probably have to scour many thrift stores or attics or go online. Digital photography is simply the norm today, and for a good reason…

The images can be viewed immediately. You can see the image on the back of the camera or download it immediately to view it on a screen.
Digital cameras offer you more control over your exposure. Not only can you change shutter speed and aperture, now a digital camera lets you instantly control ISO, white balance, and more.
A memory card, depending on size, can hold thousands of images and is reusable. There’s no need to purchase the film.
Images can be processed on a computer instead of developing your film or sending it off for outside processing and waiting weeks to see the results of your session.
Because you can view your images before printing, you’re only printing and saving the images you love.
It’s fun
Digital photography is all about instant gratification. See the scene, click the shutter, see your image. We can argue about the dangers of this mentality in another post. But the reality is, digital photography has made it easier than ever to learn photography and improve your skills.
