16.) How to do I change Mode and what is the difference between RGB and CMYK? erich //You can change the color mode by going to Edit, and then to color settings to change between RGB and CMYK. RGB and CMYK are color settings with RGB standing for Red, Green, and Blue, while CMYK stands for Cyan, Magenta, Yellow, and Key(Black) RGB is meant for the internet because it features a subtractive color system while CMYK is an additive color system that is used in printing pictures.// http://dictionary.reference.com/browse/ 19.) Define exposure, offset, gamma correction. ? --erich

//Offset: a process in which a lithographic stone or metal or paper plate is used to make an inked impression on a rubber blanket that transfers it to the paper being printed, instead of being made directly on the paper. Exposure: The amount of light an object receives. In photography a high exposure might blowout the picture, while a low exposure may be too dark. Gamma Correction:// //A correction to the contrast of images and displays, performed by either software or hardware, and designed to correct for the fact that the intensity displayed on a cathode-ray tube is not linearly related to the input voltage.// http://dictionary.reference.com/browse/ 28.) Tell me the up side and the down side of saving an image in jpeg format.CD? erich/tom

Jpeg is a smaller file size than other types (due to it being a compressed file type), therefore you can fit more of them on your memory unit, however; jpeg is compressed, so you loose information by using Jpeg because each time you re-open and save a jpeg file it gets compressed yet again, forcing it to loose even more pixels/information.
