I can see the difference in the quality of the final image compared to the previous JPEG Files. The beauty of RAW of course is that you can make some drastic alterations to exposure and white balance afterwards. In a nutshell, as long as the image is in sharp focus, you can recorrect every mistake to make a poor shot look reasonable.
The light was really poor when I took these shots, varying from low mist to bursts of sunshine. The original dull shots were barely acceptable though the exposure has been tweaked upwards to yield some fair results.
