I'd like to find my personal film speed. I'm just starting to use 120. I'm following the instructions in "Way Beyond Monochrome." I'm suppose to take a picture of a scene containing zone II and zone III shadows. Normally I'd take such a picture in my backyard surrounded with leafy bushes and undergrowth.

But during this time of year the ground is devoid of plants and the bushes have no leaves. So there's really no shadows or texture.

Where do you all find scenes with shadow detail in winter?

Any suggestions appreciated.
