  • File formats – are facilities or methods to store and organize digital images. The matter of interpreting digital image file is due to the format of storing and coding the image files.
  • Pixels – elements of the picture that are arranged and stored in a manner dictated by the format of the image.
  • IMAGE FILE FORMATS • Joint Photographic Experts Group (JPEG or JPG) • Tagged Image File Format (TIFF) • Graphics Interchange Format (GIF) • Portable Network Graphics (PNG)
  • JOINT PHOTOGRAPHIC EXPERTS GROUP (JPEG or JPG) - This is a compression method that complies with the (?) File Interchange Format (JFIF).
  • JOINT PHOTOGRAPHIC EXPERTS GROUP (JPEG or JPG) - This format applies "lossy" compression method to image files, which means that a huge number of pixels are lost or discarded in storing the image.
  • JOINT PHOTOGRAPHIC EXPERTS GROUP (JPEG or JPG) - The information is not lost, however, but a great space for storage is saved.
  • TAGGED IMAGE FILE FORMAT (TIFF) - This is a less common file format supported by Web browsers.
  • TAGGED IMAGE FILE FORMAT (TIFF) - This file format can use either the lossless or the lossy compression method.
  • GRAPHICS INTERCHANGE FORMAT (GIF) - This is a popular file format for storing graphical image with fewer colors.
  • GRAPHICS INTERCHANGE FORMAT (GIF) - This file format supports 256 colors only.
  • GRAPHICS INTERCHANGE FORMAT (GIF) - (?) compression method uses lossless compression techniques.
  • PORTABLE NETWORK GRAPHICS (PNG) - The intention for the creation of this file format is to be a free and open source substitute for GIF.
  • PORTABLE NETWORK GRAPHICS (PNG) - This file format is expected to be fully compatible with online applications.
  • PORTABLE NETWORK GRAPHICS (PNG) - This is a lossless compression method; thus, it is also used in editing applications.
  • Image editor - is an application that contains tools that can alter digital photos and images.
  • Image editor - This type of application is used to enhance photos and is typically used in graphic editors and artists.
