It's a lot better than nothing but I really would recommend Noiseware Professional, it's outstanding in my opinion.
Exposure is not my problem, I usually get it right but somehow everything looks dull and boring. The lighting is the main problem as it's mostly overcast skies here in winter .I use aperture priority, between +1.3 to +2 EV and spot meter the snow. It's odd, but it works to avoid overexposing the snow and actually exposes everything else well too.
Want I should write a little article/thread?
