File Types

RAW file advantages:

1. Its uncompressed which means more data from the sensor is saved, making a better picture.
2. Higher in dynamic range  (ability to display highlights and shadows).
3. Much more editing possibilities

RAW file disadvantage:

1.  lower in contrast (flatter, washed out looking).

JPEG file advantages:

1. A standard format readable by any image program on the market or available open source.
2. Fairly small in file size (an 8 megapixel camera will produce JPEG between 1 and 3 MB’s in size).
3. Sharper.

JPEG file disadvantage:

1. Lower in dynamic range.

Questions:

1. RAW doesn’t process the photo within the camera, it captures all the data and retains all the information without compressing it, preserving all the information in all the pixels within the image.

2. Photographers can edit shadows, highlights, color balance, and more.

3. If their memory cards are large enough, if they really need their files to have HDR.

4. A photographer would need to know all of the advantages and disadvantages of RAW files so they can make an informed decision on whether or not to use it.
