Camera Digital

1.0  Background

A digital camera uses an electronic image sensor to create still photographs and record video. The optical system of a digital camera works like a film camera, in which a typical lens and diaphragm are used to adjust electronic image sensor lighting.

Digital cameras equip amateur and professional photographers with multiple automated control functions. Advanced digital cameras facilitate manual control of most functions. A digital camera is also known as a digicam.

3.0 Advantages digital camera

3.1 Planning Your Shot

Before digital photography, people were limited to a maximum 36 photos per roll of film. Unless you had a Polaroid, there was no way to see the photo immediately after taking it. Developing and printing all the photos on the film was fairly expensive, so you had to take care not to waste shots. The advantage of a digital camera is that you can immediately see your images on-screen, and you don't have to develop a roll of film. Every failed shot can be deleted on the spot, so you can take a whole bunch of photos and then select the best ones. The disadvantage of this technique, however, is that you tend to not focus on getting the perfect shot as much, exercising quantity over quality when composing your image.

3.2 Number of Photos

As of 2013, camera memory cards come with capacities of up to 64 gigabytes. This means one memory card can store thousands of photos. This is in stark contrast with film photography, where you were limited to 36 photos on a roll of film. When film got damaged, the photographer would lose 36 photos. However, if your memory card gets corrupted before you have had a chance to download the photos, you could potentially lose thousands of images at once.

3.3 Editing

Digital photography allows you to edit your images after uploading them to a computer. This allows for very creative effects, and gives you the freedom to correct faults in photos that are, for instance, underexposed. It is now possible to turn an image to grey scale digitally or to remove elements from the background. The downside of this is that, once again, people tend to be less critical about their photos because it could be corrected through editing. Instead of getting the shot right from the start, a lot of time is spent editing away mistakes. Photos are also often over-edited, taking away from their natural beauty.
