Seeking advice for 10 stop ND filter in high key

[crasher8]

I'm spending Thanksgiving in Sun Valley and will be shooting a variety of wide and UWA landscape scenes. i.e. Baldy, the Lodge, Sawtooths etc.

I've had good learning experiences this fall with my B+W 3.0 10 stop ND filter but have yet to try it in a snow covered or high key scene.

Any tips would be appreciated.

TIA
