Hello Kieth, I hope that you do not mind my very "rough" edit of your image. (I note the halo and a number of other issues that a longer edit would remove.) I wanted to see how much data was in the shadows, and a very quick play in between stacking boxes for our house move.
I know your post, and photographic aim is to capture everything in camera and that is fine, but I have to say that IMHO, the camera is now, more than ever, a data collector. I know for many images the camera can be tuned to produce very good out of camera images, but as I think was posted earlier, to some extent that is merely moving some choices into the camera processor.
A "null setting" on most dSLR's I'e used produces a pretty disappointing images straight from the camera, with different RAW convertors handling things in their own way as well. I think for many subjects a degree of PP adds a layer to an image, converting it from a sensor capture, to an expression of how the photographer experienced the scene, and with digital the box of tricks is nearly endless.
Please note I will remove the image and delete the jpegs from my drive when the post "dries up" or if you wish me to.
