There are many advantages in digital imaging. Before its development, people are using film cameras that do not provide the person a preview of the image to be taken. The one taking the shot is not aware if the image taken was good enough and was really the desired image. The images that can be taken are also very limited and no editing and manipulation can be done after the image is taken. Pictures taken from film cameras cannot be viewed until the pictures are developed in a specialized setting. This means that the pictures need to be printed in a piece of canvass and this is an additional cost to the person. In digital imaging, with the use of digital cameras, the person taking the picture can see the image prior to storing the picture in the camera. After taking the shot, the person can check then go through the pictures and decide if the desired shot was taken. If the shot was not likeable, then the person can easily delete the picture and take another one. It can also store many images depending on the memory of the device. When it comes to storage of pictures, the person can decide not to print the pictures but instead, transfer the images to other devices like the computer for permanent storage and future viewing. Those who need a print copy of the picture can easily access the computer and immediately print the pictures with no hassles and additional costs. This has affected certain businesses in printing and this was evident in the decline of their transactions and profits. Digital images are also long lasting and do not easily degrade in quality, even if the images are transferred from one device to another. Since a digital image is made up of pixels it can be easily edited in many ways for entertainment. They can make modifications with the colors and other necessary changes needed to make the image look good. Designs can also be added depending on the available options in a computer program.

Since its development, digital imaging has produced a great impact to the people. It has been widely used in different fields. In hospitals, digital imaging becomes helpful in making appropriate diagnosis for patients since images that are taken can be processed right after an image is taken. Data stored can also be used for future studies regarding a certain condition as shown in a digital image. Photographers for magazines and newspapers greatly benefit from digital imaging since it becomes easier for them to send images immediately through the internet at a short period of time. In advertising and fashion, digital imaging helps operators make necessary changes with a certain shot. They can immediately make judgments on certain shot and improve the next shots to save time and money. The only known problem with digital images is that those pictures taken and stored in computers, cellphones and other devices are easily lost when the device malfunctions. Therefore, back-up files are necessary to avoid losing stored images despite this, digital imaging can still be considered as imaging at its best.

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.
