 When edited in suitable software, such as Adobe Photoshop or the GNU program GIMP (which uses dcraw to read raw files), the user may manipulate certain parameters, such as contrast, sharpness, or colour balance before producing an image.JPEG images can be similarly manipulated, though usually less precisely; software for this purpose may be provided with consumer-grade cameras.Digital photography allows the quick collection of a large quantity of archival documents, bringing convenience, lower cost, and increased flexibility in using the documents.
