Kelly and I were discussing RAW vs JPG, and being civil about it!

I went back to do more research on RAW and here is some of what I found:
Some of us photograph in JPG. It is much more efficient due to the smaller file sizes and has little or no need for post processing.
Some of us photograph in RAW. It has much more information, thus a potentially higher quality image. The key word though is "potentially", as in does this larger file size really translate into greater image quality?
A look at some JPG images confirms the JPG photographers are obviously getting the high quality they need to satisfy their customers. Would RAW give even more, is more even needed or worthwhile, or is all this just more marketing hype?
*Before adding to this thread I greatly encourage readers to read the following essays on RAW. They *are* biased toward using RAW so please take that into account. If you agree or disagree with them, good, but please explain why. I also strongly encourage you to read about the Zone System.
The excerpt below is taken from the second essay.

JPEG Shooter - The camera captures RAW data, and it then develops the image into a JPEG or TIF. The RAW data is discarded. The photographer gets the cameras rendition of the file and is essentially stuck with it unless a loss of quality is to be tolerated through editing. And this may be OK if all the parameters like exposure and White Balance were properly set in the camera. But in the real world that is rarely the case 100% of the time.
RAW Shooter - The camera captures RAW data, and it then saves the RAW data onto the memory card for future development(s). The RAW data (ALL of the captured data) is preserved. The photographer gets the full potential of the image, and will maintain that potential forever by archiving the RAW file. (With many cameras, you can shoot RAW + JPEG which saves the JPEG and RAW files to the memory card. Perfect except for the extra space this consumes, but a great transitional mode while getting used to or experimenting with shooting RAW).
RAW Truth #1
The JPEG shooter and the RAW shooter both capture RAW data. The JPEG shooter uses the camera as their RAW converter (developer) and is willing to give up the potential to do a better development in the future. The RAW shooter, saves the RAW data (and maybe a camera developed JPEG as well) so that the potential of the image can be maximized by using his or her RAW converter of choice.
end of plagiarized material.

From all the information I have been able to gather, the RAW file can not be directly displayed. What we are seeing is the RAW file converted to a viewable format, with the camera settings (or the RAW converter settings) applied. The big deal is that the settings are applied only to that conversion, the RAW file itself is not altered. Because of that we can go back and change the settings and convert the RAW file as many times as we wish, always starting with the original instead of compounding the changes (and losing data at every step).
This doesn't seem much different from altering the JPG several times (but always starting with the original as well), except the original JPG has already been converted from the RAW by the camera (according to it's settings) and data has already been lost. It appears if we wish to use JPG we might be best off with the minimum settings except that means more post processing outside of the camera, something that we are trying to get away from by using JPG in the first place!
My needs are different from a professional, I am not a pro and have no screaming clients so I have the luxury of time to post process every image if need be. I usually combine a small JPG with the RAW for viewing and emailing, and I print a very small percentage of my images anyway so it's not a big problem. In the case of a pro I can only imagine the havoc that would result from being forced to spend a lot of time processing every image, for a client who wants them *now*. I read an article on SuperBowl photographers and naturally they shoot JPG because of the huge number of photos the Sports Illustrated editor has to view, even during the game.
A typical sunny day scene can have a brightness range of over 10,000:1, our sensor can record maybe 4,000:1, paper can display about 200:1. Obviously "correct exposure" can mean many things, as in correct for which part of the scene? There is no way the exposure can be correct for all parts of a high contrast scene, we cannot capture that much range of brightness. RAW can capture more of it than JPG so I use RAW to give me the most options.
So as far as I can figure, yes, RAW can provide a higher quality image but it comes at a cost and is not always the best choice for the final output.
