9. 1) Jpegs don’t support layers 2) Jpegs are called “lossy” image. Information is lost when it is converted to jpeg in the camera and quality is lost when opening and closing files. 3) Jpegs only support 8 bit images!! (today’s camera sensors can capture 12 and 14 bits of color data and most raw editing software supports 16 bit raw images.) 1) Jpegs compress the images and the file is smaller then most. Thus you can fit more photos in your cameras memory card and Smaller in size uses less space on computer hard drive 2) File is recognized by most printing services like Costco or Ritz etc. 3) Images can be emailed and uploaded on websites easier then other formats. 4) Need no in computer converting or other programs to print etc. Jpeg (industry standard) (images are processed in the camera) Cons Pros File type
