Digital images show us the path to the person’s thought process and gives an insight to one’s mind. The way an individual perceives a view and conceives it through a digital image reflects a lot about the thinking and the personality of an individual  Hence, it can be rightly said that digital image has become an important mode of communication which is artistic yet self explanatory.
We shall now take a look into other facets of digital images corresponding to current scenario.

4.1 Own use of digital images in meeting the requirements

This sub-section discusses the design constraints of digital images, their considerations and originality.
Design Constraints
The design constraints takes care of the enhancement of the quality of pictures. The availability of free and paid softwares has made this possible. Adobe photoshop is the most effective software used in this. Online photo editors are also available. While designing the images one should always take into account the size constraint which is limited to 10 pixels.

Color correction

It is been taken care by Adobe photoshop. the originality of the image  should not be lost while color correction. The enhancement shall not diminish the main perception. Color correction consists of Layering, filtering, saturation and creating hue. 


Original images are captured and then processed. They are primarily edited, modified and altered using Adobe photoshop. It is made mandatory that the original essence of any image is not lost.
The points to be kept in mind:

  1. the original essence of the image should not be lost.
  2. Too much of editing leads to artificial image, hence diminishing the originality.
  3. Pixel size should be maintained
  4. Design Constraints in terms of storage size and capacity should be kept in mind
  5. Legal and authorised used of digital images. Clicking of vulgar digital images is punishable (Russ, 2001).

4.2 Others’ use of digital images in meeting specified purposes.

The use of secondary digital image is also allowed herein. It is thereafter modified using Adobe photoshop. The internal characteristic of digital images leads to lesser design constraints. Others have used images of higher pixels which allows easier altering of images. As there is filtered stage in secondary sources, design constraints are less. It can be thus concluded that depending on the medium and nature of use, digital images can be used differently.
In this part, we will be analysing the work of my colleague. In his project, he has emphasized more on primary images; hence, due to the lack of good photographic devices, he failed to produce good quality images. Therefore, the images taken by him are of lesser pixels. Even if Adobe Photoshop is used to edit and modify those images, the quality might not be improved much. However, higher color correction methods have been executed at the maximum possible level. Most of the images used by him abided by the Copyright laws as there was no need to credit sources.
As we already discussed digital images have become important tool in the mode of communication. It caters to expression of thoughts, ideas etc.
They play an important role even in the new age cinematography. Animation films, advertisements, banners earn a lot of revenue and helps in economic growth. Insted of painting images and using it as a banner or advertisement, the new age software have made it much easier. It is the new world of digitization. Storing digital images is no more a challenge, thanks to the new age mini chips with Tbs of storage space.
Digital images are quite vocal and effective in spreading awareness regarding any social or political change. Visual demonstration has a better impact on minds rather than verbal or written media. Illustrations regarding anything and everything is carried out and has proved to be effective.
Moreover, it has been a boon for the medical world. Digital imaging has helped to faster detection of any medical emergency and has been instrumental in saving lives.GPS system has helped in tracking a particular location thus helping reducing criminal activities to an extent. In a greater perspective, movement of celestial bodies can also be detected and has opened a horizon in the field of Science and technology.


The report concludes that digital imaging has brought about the age of digitization and has technologically brought an advancement in the human breed.
