Hi M. Gustave,
With all due respect your reply is so nonsensical as to be quite humorous. It obviously shows that you've never learned how to process an image let alone a raw image. Lagwagon is quite correct in his assessment in all comments. For those who think that for years photographers only took photos and did no post processing did not understand photography in "the golden years" or never did it.
If you think that Ansel Adams just went out there and snapped photos, you are very mistaken. Please read up on what he did and how, there is a lot of material out there to explain his process.
You owe it to your self to learn more about this. But one reality that might give you a place to start: a JPEG image is an 8-bit image: 256 shades (or tones) of red, blue and green. That's it. If any part of the image is blown out (over or under exposed), too bad. If there is light from another room leaking into your image, too bad. If you want to make changes overall exposure in parts of an image beyond a single stop, again, too bad. There are many many other dynamics that can be fixed when raw that are out of reach if the image is cooked (jpg).
The composition of your images may be fine, they might even be fantastic, but why you willingly wish to tie yourself down to end up with poorly processed image because you do not want to use the full set of tools is beyond me. If you think your images are good, try adding to your level of expertise and learn how to process raw images properly. If quantity is quality, I've got you beet as I've taken over 20,000 photos since the mid-70's and once I got a camera that could do raw, I've never taken a jpg since. I value what I can do in the darkroom or the computer.
Most of today's camera have 14-bit sensors so that means over 16,000 shades (or tones) per channel. Admittedly, most screens cannot display anything near that and most of the printers we are likely to purchase cannot print anything near that but consider when you've done some image manipulation that now starts to display posterization. You WILL NOT get that from a raw image but you are sure to get that from a jpg.
To provide some help on this, let me point you at a friend of mine's website, Laura Shoe, who provides some extra insight on this. See <

To reiterate, you really do not know what you are talking about and you seem to have no clue about what you do not know and are providing some very wrong information.
