Auto DRO (dynamic range optimisation) is the most pronounced. It'll attempt to put some tone into overexposed areas and put some light into underexposed areas on an per exposure basis and write it into the OOC JPG. It works very well but you'll never know quite what it did, so emulating the effect (arggghh ... just noticed my effect/affect boo-boo in the post above) for the RAW becomes guesswork/trial and error.

Dynamic range will be hugely better with RAW and your software should be able to fetch it out. Having tried a whole bunch, I ended up buying Photoninja which although is a bit more expensive than Lightroom, is easier to use and gets nicer results. For pure RAW processing, it's better but it doesn't have the photo organisational capabilities of Lightroom.

I kind of chose to leave them like that or even enhance that effect as it seemed to reflect the moody atmosphere up there - the light really seems quite different." <
The exposure may be due to a spot or scene setting ? If you use your cameras on an auto mode rather than fully manual, and Sony's exposure for example was set on centre spot, pointing at snow, it will take that as the 'grey point', choose a shorter shutter speed or a smaller aperture and 'underexpose'. If your Canon had been set on a multipoint exposure, it would look at the whole scene (dark skies and clouds too) and would relatively 'overexpose' compared to the Sony. Colour is a mystery and even varies from one model to the next. My Canon S110 was a shocker for putting excess magenta into its OOC JPG's in snow scenes.

Would love to. A Norway ski tour is on the lotto win bucket list, as is a summer cycle camping tour. Hoping for some decent aurora shots from here in Moffat some time but the cloud keeps conspiring against me.
