I'm wondering does post processing in Lightroom and Photoshop take the place of shooting in RAW?...Julian
For years, I shot saving only JPEGs. I worked hard to get exposure, white balance, and other basic parameters correct initially, then used the Microsoft Photo Editor to make adjustments. Final results were quite good. And when exposed properly, JPEGs capture pretty much the same dynamic range that most printers can reproduce. Because I do a lot of railroad photography, which involves sunlit subjects that also have areas of shadow including lots of detail that is needed in the final image. My answer to that was High Dynamic Range Photography, which is really just a specific discipline of pre and post processing to integrate a wider range of exposure values into a final image. My HDR still was based on JPEG captures, but most HDR software utilizes an internal "working format" with more bit depth even if the overall process is JPEG to JPEG. Finishing was either done with the HDR software, Photo Editor, or sometimes Nikon's supplied and purchased software.
I still capture images in JPEG, but I now also save a raw version of every image. And I still work to do the best job possible to make certain that the JPEG is as close as possible to a finished image. That way, I not only have a nice image to share immediately, but I also have the best possible starting point for finishing the raw image, making that job much easier and faster. It is very rare now that I'll capture a bracketed set of images for HDR processing. A properly exposed 14 bit raw exposure has plenty of latitude in all but the most extreme cases (like shooting at high ISO, where dynamic range captured can be limited), and almost all of the same benefits can be realized by adjusting the shadows and mid tones.
Many here suggest that when shooting raw, camera settings resulting in dull, flat images are best, then they work to restore everything in post processing. Many also either use auto-WB or just ignore it altogether, fixing it later. I've tried that approach, and do not follow it. It seems to me that it creates a lot of unnecessary work, and if it happens that I can't remember exactly what the scene looked like, or what specific details in the scene looked like, the job of trying to recreate it, or at least an attractive version of it, can be very difficult and frustrating.
Not sure this post answers or addresses what you are asking about, but the point is that yes...images not captured in raw can be processed. If they are exposed properly, the results can be very attractive and can be printed readily. If there are errors, primarily underexposure, there may not be enough captured information to allow a successful repair. If you are wanting to do some really radical editing, there may not be enough room available in the 8 bits per color that you have available to do it and save it. And if you don't make the proper choices when setting up to capture and save JPEGs, you may lose a lot of the information that you do get.
