Sorting Main Differences between Analog(with Film) and Digital Photography
What is an Analog Camera??
In an Analog Camera,the external structure may more or less seem similar,but it's Photo capturing principle is primarily based on storing clicked pictures on a film.
A picture taken on film is composed of numerous, tiny, light-sensitive silver-halide crystals that are chemically-processed in order for the image to be made.
Now,what is a Digital Camera??
In this, the photo capturing principle is entirely differnt from that of an analog camera.
the picture information here,is stored on a 'Digital-Sensor'.
This sensor is Semiconductor diode,which converts incoming light into various pixel intensity values.
There are mainly two types of sensors available in market at the moment..these are-"CCD type"
and "CMOS type".
CCD is a Charged Coupled Device,whereas CMOS is a Complimentary Metal Oxide Semiconductor.
A picture recorded digitally is made up of numerous, tiny, light-sensitive pixels that form an image that can be viewed on a computer monitor or the viewing screen of some digital cameras.
Most digital cameras function in much the same way as a traditional camera that uses film to record images, except that in place of the film, images are captured and preserved in the camera’s digital memory, which may be built-in or which may be on a removable memory card.
The number of images the camera’s memory or memory card holds varies dependent on image quality and type (i.e. black and white, color or sepia-toned), the quality of the camera and the memory capacity. New technology for digital imaging is emerging rapidly and multi mega-pixel image storage capacity is quickly becoming affordable with each new generation of cameras.
A great advantage of many digital cameras that have an LCD viewfinder (a mini monitor screen) is the ability to review images stored in the camera's memory at any time and to delete any unwanted images at the photographer's convenience, thus freeing up storage space for new images, while retaining only the best images for later retrieval and downloading.
Digital imagery is the fastest-growing area of photography, with changes and improvements in products and techniques occurring almost daily.
