Scanning and optimising images Photoshop in pdf

There is little doubt that the use of digital images in learning, teaching and research projects is growing. Typical uses include: supporting lectures and other presentations; creating Web-based instruction and creating digital image archives. Another aspect of digital images is that they can be delivered on a variety of supports: PowerPoint, Web, image database, CD-ROM and print. It is therefore important to be familiar with image digitisation processes in order to obtain images that will be ‘fit for purpose’. 

Scanning provides a means for converting traditional film images to the digital format, where they can be manipulated and enhanced just like any digital image. 

This course shows you how to make better use of your scanner and apply image enhancement techniques using Adobe Photoshop.
