Image Formats Lesson Plan
The photo industry operates with certain key image formats. Knowing the relative strengths and weaknesses of each is fundamental if you are going to know what you are doing in your interaction with clients and with picture libraries and perhaps, more importantly, if you are going to build a long-term archive that grows in value over time and remains accessible decades from now.

Camera raw file formats
Camera Raw image files are 'raw' in the sense that they are untouched and have not been altered since the photograph was taken. The raw file contains the image data as the camera recorded it.
Tiff file format
Why is Tiff the de facto archival file format? It is great for long term archiving, but there are certain settings you should avoid if you want to use it as an archival format.
JPEG file format
Jpeg is the most widely used compression format. But it has some significant disadvantages if you do not handle it correctly.
