File Formatting
PART I. http://digital-photography-school.com/raw-vs-jpeg/
Three advantages of a RAW file; The complete (lossless) data from the camera's sensor. Higher in dynamic range (highlights and shadows). Lower in contrast.
One disadvantage to a RAW file; Not as sharp.
Three advantages to a JPEG file; Immediately suitable for printing, sharing, or posting on the web. Sharper. Processed by your camera.
One disadvantage to a JPEG file; Lower in dynamic contrast (highlights and contrasts).

PART II. http://photography.tutsplus.com/articles/quick-tip-what-is-raw-and-why-might-you-need-it--photo-8436
1. Under the first heading, "Capturing the Images", how much of the data does a RAW file retain after it is captured by the camera?
The RAW files take up a significant amount more than the JPEG files.
2. Under the second heading "Processing the Files", what are some of the things that a RAW file enables a photographer to edit after the image is taken?
RAW files enable the photographer to have a more creative range of tools to use in order to enhance the photos.
3. Under the third heading "Practicalities", what are some of the factors that photographers must consider when deciding to shoot in RAW?
Photographers will need to keep in mind the size of the RAW files and the fact that their memory cards might mot be able to hold too many shots.
4. Under the fourth "Which one is for you?", why would an aspiring professional need to know how to work with RAW files?
Aspiring professional photographers may be looking into using RAW files because of the more options that a RAW file editing software offers. It will also give you great, need-to-know editing skills and developing techniques to enhance your photos.

PART III. http://en.wikipedia.org/wiki/Image_file_formats
1. Which file formats discussed have you used in the past?
The file formats that I have discussed or been shown in the past are as follows; JPEG/JIFF, JEG 2000, GIF, PNG, and BPG.
2. What is the difference between a Raster and a Vector file?
The difference between Raster and Vector files are that the Raster files are composed of pixels and the Vector files are composed of paths.
--------------------------------------------------------------------------------------------------------------------------
PART IV. (Same link as above)
1. Is this format lossy or lossless?
Raster files have a lossless compression whereas Vector files have a lossy compression.
2. What are common uses for each?
A common use for each is when you are downloading files and trying to edit them, how the quality of the photo looks based on the compression type you decided to use.
3. Can you create this type of file in your camera?
Yes, you can. Especially in any Canon camera.
