The Wonders of Digital Imaging

As this era marked the digital age, it is not surprising anymore that even snapshot images have also gone digital. With the birth of digital cameras and camcorders as well as other digital equipment such as scanners, images nowadays have become more “modernized” as a simple original image can be reproduced many times in different looks.

Digital imaging, as its term entails, involve the use of digital equipment or compute in the process of making an image – may it be an edited copy of an old image, or simply a new image taken through digital camera or recorders.  Digital imaging has also now become the world of mouth in the world of photography and films as the use of digital application in images make the outputs more artistic looking and appreciated well by this modern digital age.

Aside from the use of digital equipment, digital imaging primarily relies on computer programs that enhance images digitally.  There are a lot of programs right now that do such; producing images which humans never thought will be possible.  The following are some of the basic tools used in digital imaging:

Compression. This involves the reduction of image size to fit it into the saving destination.  Image can be compressed either “losslessly” or “lossyly.” In lossy compression, images are compressed into a lesser size image by “losing” some information in order for it to be reduced.  Although the image is retained in a macroscopic look, there are some bits out from it that was deleted during the compression. A good example for this is the JPEG image format.  The lossless compression, on the other hand, is a compression of image but does not involve losing of information, unlike the lossy compression.  In lossless, the image is just compressed into a smaller size upon saving. In opening the file, however, there is a need to decompress it – the opened image still looks the same that of the original image. An example for this is the TIFF image format.

Noise reduction. Digital images are prone to have “speckles;” hence, it needs some digital editing to reduce the “noise” or simply to smoothen the texture of the image.  This can be done without alterating the entire image.

Sharpening and Blurring. Digital images can have blurry and sharp effects, depending on how the image will be projected.  Some digital cameras have already built-in sharpening program tool wherein one can just simply do it after taking every shot of image in the camera.  Sharpening or blurring levels usually range from low to normal.

The abovementioned applications are just few of the many digital imaging programs that help enhance images.  It should be considered highly, however, that these applications are useless if the one who has it do not know how to use it. Knowledge about digital imaging is a must in order to achieve the desired image the person wants to have. Knowledge of such can be gained through seminars, training or acquaintances with fellow digital imaging editors. Furthermore, one can also have self-learning such as reading training material and researching (especially over the internet) about the latest innovations about digital imaging.

Meanwhile, it should be taken into the mind that digital imaging is just a process or tool to further beautify the images. The alterations should not be observed if one’s aim is just to deceive people over images that are not really natural or true.
