While a lot of personal Web pages could be viewed as bandwidth clutter, for many people, posting their own page on the Web is an exciting development in their use of the Internet and is a way of making likeminded friends and contacts the world over. When you get it home, do a few experiments in order to correctly set up your default settings. Scanners generally come with free photo manipulation software, which is suitable for most people's Web activity, however, if you're serious about quality and want better control when manipulating images, there are several software programmes you can install in your computer. The version we used, Adobe Photoshop, is the publishing industry's standard for photo composites. A Macintosh's gamma level is 1.8, while a PC's is 2.2, therefore, if you scan in an image and manipulate it on a Mac and then try to view it on a PC, it would look too dark.
Magazines use bitmap images for much of their artwork.
Quality glossy magazines use 2400dpi and upwards, but the maximum usable resolution on the Internet is 72dpi, because most users' screens can't display any higher resolution on their screens. These file types are limited to 256 colours and typically don't compress as well as JPEG graphics. JPEG files can have millions of colours. JPEG is more likely to lose an excessive amount of detail if the image has a sudden transition from one colour to another, so try not to use this format in graphics containing text, line drawings or navigational icons. Do most of your changes in Photoshop and reduce file size and resolution when you're saving it as a final file type at the end of the process.
