![]() 2 x 1 colours, which are black and white. A bit is the smallest increment of digital information. Bitmap mode is also called 1 bit colour because there’s only one bit of information. It’s like a light switch that’s on or off. Bit depth can go way higher, but such images are rarely used in graphic design.īitmap Mode: Each pixel can only either be black or white. Bit DepthĪ raster image can go from a single bit image, in bitmap mode to an 8 bit image, in colour. Use Bitmap or Bitmap mode for pure black and white images. It’s best to use raster when refering to a pixel-based image. ![]() The phrase black & white is also often misused, interchangeably with greyscale. Sometimes it refers to a black & white image. The term bitmap has multiple definitions. Pixel dimensions refers to the number of pixels for the height of the image and the width of the image. Pixel Dimensions People often use 'resolution' where I use 'pixel dimensions'. So a 1920 x 1080 pixel image has 2 million pixels, which can also be expressed as two megapixels. With images for the screen, resolution is the total number of pixels in the image. In print, resolution refers to how many pixels there are in a linear inch of the image. Let’s assign terms to concepts Resolution This term is used in many different ways. ![]() Terminology relating to raster images is rather flexible. As a graphic designer, you’ll be manipulating raster images for many different intents: high-end printing, app & web design, large format signage, etc… Being aware of the mechanics of what’s happening to the pixels in your images is crucial to successful reproduction. ![]()
