I did a little test today regarding shadow recovery/underexposure on my RX100m2. I put a test chart under a bright lamp, put a ND filter on the camera and took 3 different shots. These I imported in Lightroom and bumped the exposure up around 4EV until they were correctly exposed. First the JPEG As expected it's pretty bad. But JPEG files aren't really made for such heavy manipulation. Then the raw file Much better I think. Obviously not on the level of larger sensors, but quite respectable, and definetely something I could work with. The last shot is also a JPEG, but shot with DRO level 5 turned on. It really surprised me how much better it turned out than the regular JPEG. In Lightroom I had to up the exposure by about a stop less than the raw file, so obviously the camera did something. Basicly my conclusion is to view DRO as in-camera shadow recovery done before the raw conversion. This means that the DRO files are much easier to work with if you for some reason want to post process JPEGs instead of working on the raw files. I've been doing this recently, as I'm using Snapseed on my tablet to PP so I need JPEG files. Setting DRO to level 5 and underexposing the shot by around 1 stop gives me some nice and flat JPEGs with greatly reduced chance of blown highlights. Snapseed lets me bring back contrast very easily and I can always darken the shadows again to the degree I need it. Anyway, this was probably obvious to everyone else, and I've just been rambling, but I found it interesting to do a more controlled test instead of just going on the gut feeling I had from my shooting.
