good day...

i am currently purchasing gear from an upcoming trip to banff/jasper. i'll be shooting velvia and neopan across. i've pretty much settled on everything, sans the best set of filters. from reading other threads, i've decided on:

-polarizer (though wavering between hoya moose 'warming' or b&w linear non-warming)

-#25 red

-either a #15 Dark Yellow or #11 Yellow-Green

i'd like to add some drama to the sky and a little seperation to the trees when shooting with the neopan. have any of you experience with these filters? i know the #15 will darken the sky, but will it also lighten the trees? my concern with the #11 is that the effects will be too slight.

thanks, scott
