[pure-silver] Re: Green vs Yellow filters

Alan, I find that it is best to have several. Not everyone's skin is the
same nor is all foliage the same. After playing with the various greens
available under several lighting conditions, mid day, morning, evening
you'll know which one to grab when. You might even consider split tone
filters for more local control of tonal adjustments.
