Lossy versus Lossless


Advantage of RAW: Higher in dynamic range, complete data from the camera's sensor, and uncompressed.
Disadvantage of RAW: not as sharp

Advantage of JPEG: Higher in contrast, sharper, and immediately suitable for printing.
Disadvantage of JPEG: Lower in dynamic range


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?
It captures all the data


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?
white balance, contrast, highlights, shadows, colors and saturation


3. Under the third heading "Practicalities," what are some of the factors that photographers must consider when deciding to shoot in RAW?
not every camera will shoot in RAW and RAW files are larger so there won't be as much space on the memory cards. 


4. Under the fourth heading "Which one is for you?" why would an aspiring professional photographer need to know how to work with RAW files?
It gives you more flexibility and processing options. Editing is important for the future.
