Photography : Analog and Digital Photography

What is Analog Photography?

Analog Photography is the form of photography in which a film roll is loaded into the camera for capturing the objects. When the button is clicked, the light reacts with the chemicals on the film roll to capture the object.

A film roll is nothing but a photographic film rolled in the form of a spool and protected from exposure to light by using the paper cover. It usually has markings for each frame and it rolls over to the next frame for capturing the next object.

When the film roll is fully exposed, it is unloaded from the camera and taken to any photographic studio for developing the images using a chemical process. The process involves using liquid chemical solutions to wash the film roll for developing the images.

The only way to see the images is to print that on a sheet of paper. The number of images that can be taken depends on the size of the film roll. Instead of films, electronic sensors like CCD (Charge Coupling Device) was also used in Analog Photography.

What is Digital Photography?

Digital Photography has created a very big revolution in the field of Photography as it completely removed the use of Photographic films and the chemical process for developing images. It uses a series of light sensors (also called Photo-detectors ) to capture the object which is focused by the lens of the camera.

The images are developed with the use of a computer instead of chemical processing. In the past, the developed images could be stored in the hard drive of a computer or floppy disk. Nowadays the images can be stored in a USB drive, CD, DVDs and more.

The number of images that can be taken in digital photography depends on the size of the internal or external memory (using a memory card) of the camera. It is possible to take more photos with digital photography than using the Analog Photography.

Digital photography has made the sharing and storage of photos very easy and flexible when compared with Analog Photography.
