15. © C.R. Business Education Creations Explain compression as it applies to graphics. Compression in graphic files is the process of reducing the size of the image. The reduction in file size allows more images to be stored in a given amount of disk or memory space. It reduces the time required for images to be sent over the Internet or downloaded from Web pages. Compression in graphic files is the process of reducing the size of the image.

16. © C.R. Business Education Creations Two Kinds of Compression Lossy - The JPEG image file, commonly used for photographs and other complex still images on the Web, is an image that has lossy compression. Using JPEG compression, the creator can decide how much loss to introduce and make a trade-off between file size and image quality.

17. © C.R. Business Education Creations Two Kinds of Compression Lossless - The Graphics Interchange File (GIF) is an image format used on the Web that provides lossless compression.

18. © C.R. Business Education Creations Two kinds of compression Lossless compression does not change any pixel data. Lossless compression never discards any information about the original file. This makes the file size larger. Lossless compression does not change any pixel data. Lossless compression never discards any information about the original file. This makes the file size larger.

20. © C.R. Business Education Creations What is resolution? Resolution is the density of pixels in an image. The standard resolution for the internet is 72 ppi (pixels per inch). The higher the resolution, the sharper the image. Resolution is the density of pixels in an image. The standard resolution for the internet is 72 ppi (pixels per inch). The higher the resolution, the sharper the image.

21. © C.R. Business Education Creations Resolution Resolution is expressed as Dots Per Inch (dpi) when printed, or Pixels Per Inch (ppi) when viewed. The dpi measure indicates the quality of the image The higher the dpi value is, the higher the density of visual information that is available to represent the image. The more visual information there is the sharper and more color rich the image. Resolution is expressed as Dots Per Inch (dpi) when printed, or Pixels Per Inch (ppi) when viewed.

22. © C.R. Business Education Creations Resolution If the image is enlarged, the dpi value decreases If the image is reduced in size, the dpi value or resolution increases. Just remember that the lower the resolution, the fuzzier the image quality appears. The higher the resolution, the sharper the image quality appears.

26. © C.R. Business Education Creations Choose the Best Angle Generally, the light should come from behind the photographer unless your intention is to take a photo of a silhouette. Moving to different angles gives new perspective to the photo. Generally, the light should come from behind the photographer unless your intention is to take a photo of a silhouette.

27. © C.R. Business Education Creations Centering the Subject Only amateurs always place the subject in the center of the photograph.

28. © C.R. Business Education Creations Rule of Thirds One of the most popular 'rules' in photography is the Rule Of Thirds. It is also popular amongst artists. It works like this: Imaginary lines are drawn dividing the image into thirds both horizontally and vertically.

29. © C.R. Business Education Creations Rule of Thirds You place important elements of your composition where these lines intersect.

30. © C.R. Business Education Creations Examples using the Rule of Thirds

31. © C.R. Business Education Creations Background Be aware of the background Is there a utility pole or a tree that looks like it is growing from the subject's head? Color is important too: Is your subject wearing a white shirt standing against a white wall?

32. © C.R. Business Education Creations Framing Fill the frame: The viewfinder may exaggerate what you see. You often perceive things a bit bigger than they actually are and tend not to notice 'slight' distractions. What you end up with is photographs with huge areas of wasted space around the edge and people with things growing out of their heads. Make sure your subject fills the frame. The best way to do this is to move a bit closer.

33. © C.R. Business Education Creations Drawing the eye into the Photo A line is an effective element of design because it can lead the viewer's eye. To create more effective photographs, actively look for lines and arrange them within your viewfinder to invoke specific feelings.
