  • Digital Camera: 2.1 Mp (1600 pixels x 1200 pixels = 1.92 Mp)Digital Image: 1600 pixels x 1200 pixels (Pixel Dimensions)Monitor: 800 pixels x 600 pixels or 72 ppi or 96 ppiDigital Print: 200 dpi (8 in x 6 in print from a 1600 pixel x 1200 pixel Image)

    Resolution

  • JPEGJoint Photographic Experts Group (also abbreviated jpg) and pronounced jay-peg. JPEG is compression technique for colour images and photographs that balances compression against loss of detail in the image. The greater the compression, the more information is lost (this is called Lossy compression).

    A compression algorithm that reduces file size by actually removing data from the image. The post-compressed image is different from the pre-compressed image, even though they may look identical (visually lossless)

  • TIFF(Tagged Image File Format) An lossless uncompressed image file format that produces no artifacts as is common with other image formats such as JPG. ArtifactsA visible defect in an image, usually caused by limitations in the input or output process (hardware or software).Visual digital effects introduced into an image by electrical noise during the capture process or over-compression that do not correspond to the original image being scanned. Artifacts might include pixellation, dotted or straight lines, regularly repeated patterns, moir, etc.

  • Artifacts (640x480 (no resize))

  • Aspect Ratio = Width/HeightDigital Image Aspect Ratio = 4/3 = 1.33Monitor Aspect Ratio = 800/600 = 1.33HDTV Aspect Ratio = 16/9 = 1.774x6 Prints Aspect Ratio = 6/4 = 1.5640/480 = 1.33
