General terminology
• Raster graphics: raster-based graphics refers to computer images which are defined pixel by pixel, i.e. digital photos or scanned images. This is the format utilized by Photoshop. This is the opposite of a vector-based image, which is defined by mathematical definitions, i.e. line art or flash animations.
• Pixel: A computer monitor displays all information using a grid of colored squares. These squares are called pixels. Photoshop allows you to view an image at many scales - when you see a blocky image you are seeing individual pixels at a larger than normal size.
• Dots Per Inch: referred to as dpi, this measures the level of detail inherent in an image. A computer screen is typically 1/2 to 1/3 a detailed as a printed image.
• Canvas: A canvas is the working space of an image. Typically you will adjust the canvas based on the ultimate destination of your image, i.e. in pixels or inches. Images destined for print should be no less than 150dpi, 300dpi is ideal. The screen is only 72dpi, so you will not appreciate the full detail until the image has been printed. Your screen may be larger or smaller than the destination screen, but it will typically be the same dpi. Pay attention to the overall total number of pixels in an image.
