Facts about image editing

With the use of digital technology in photography and the introduction of digital cameras, image editing has become an easier process and there are various software applications which can be used appropriately for altering the images according to one’s own choice. Prior to the inception of digital cameras, there were analog cameras and in such cases editing of images was done through a process known as photo retouching. Among the various software programs which are used in order to edit digital images include raster graphic editors, 3D modelers and vector graphic editors. These applications can aid immensely in altering or transforming the original images to give rise to new creations. There are several kinds of raster based graphic editors which are helpful in this endeavor like GIMP, Paint Shop Pro, Adobe Photoshop, Corel Photo-Paint and Paint.NET.

A notable change in the image occurs in digital cameras which support JPEG formats while in case of PNG formats the original image remains compact without any form of compression or distortion. In case of editing a part or a particular area of the image, that portion has to be selected initially. Certain graphic tools like vector based pen tools or lasso can be of help in this regard. It is also possible to resize the images according to one’s choice with the help of image scaling. A significant means of image editing in digital cameras is by cropping the image whereby unwanted portions of the image may be edited out only to retain the necessary part. Moreover it is also possible to engage in unwanted noise reduction and removal of objects in a photograph which are not required or are not integral to the photo. Image distortion and color changes are common features of image editing. Certain graphic tools allow the merging of separate images into one. The most important function of image editing is the addition of special effects which give the images a different dimension altogether.
