The ability to create and fabricate realistic imagery digitally—as opposed to untouched photos—changes the audience's perception of "truth" in digital photography. [41] Digital manipulation enables pictures to adjust the perception of reality, both past and present, and thereby shape people's identities, beliefs, and opinions.
Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]).
For images, it is the digital analogue to a photographic negative. As the master from which variations for specific uses can be derived, the digital master may be in the form of its initial capture (like an unretouched photograph) or in a form that has been somehow enhanced, reformatted or edited (like a manipulated photo or a completed film).
Photomontage of kiwifruit and lemons, digitally manipulated using GIMP. Photomontage is the process and the result of making a composite photograph by cutting, gluing, rearranging and overlapping two or more photographs into a new image. [1]
Image editing encompasses the processes of altering images, whether they are digital photographs, traditional photo-chemical photographs, or illustrations. Traditional analog image editing is known as photo retouching , using tools such as an airbrush to modify photographs or edit illustrations with any traditional art medium .
Photo manipulation dates back to some of the earliest photographs captured on glass and tin plates during the 19th century. The practice began not long after the creation of the first photograph (1825) by Joseph Nicéphore Niépce who developed heliography and made the first photographic print from a photoengraved printing plate.
Standard digital processes include the pigment print, and digital laser exposures on traditional color photographic paper. [citation needed] Alternative processes often overlap with historical, or non-silver processes. Most of these processes were invented over 100 years ago and were used by early photographers. [2] [3]
Digital Negative (DNG) is an open, lossless raw image format developed by Adobe and used for digital photography. It was launched on September 27, 2004. [ 1 ] The launch was accompanied by the first version of the DNG specification, [ 2 ] plus various products, including a free-of-charge DNG converter utility.
