Now, on to the photography part of the post. As much as I enjoyed doing the paintings along Cascade, I was almost more excited to indulge in a photography bender using this ND filter I mentioned, so I carried my tripod, both camera lenses and the streamlined plein air get-up on our Friday hike, specifically so I could take photos of the falls we'd seen the week before.
For those who aren't familiar with this particular piece of equipment, this Wikipedia entry explains it better than I can. When photographing moving water in normal sunlight conditions, you need an ND filter in order to obtain the soft water effect:
1/50 sec @ f/22 - no filter
|Limestone Steps, Cascade Creek|
0.5 sec @ f/22 + filter
Maybe not everyone likes the soft water effect in photos, but I love it. Always have.
As you can see, even stopped down to the smallest aperture (like other gauges, the larger the f-stop #, the smaller the aperture; for my 18-70mm lens, f/22 is as small as it gets), the shutter speed is still to fast to produce that effect.
Enter the ND filter. Why make your own? Because they can be pricy - most run $50+. On the outdoor forum I read, someone posted about making one that cost less than $10, and I was all about that.
Here's all you need:

I used it to shoot Engine Falls on our hike up the trail, but after I'd finished, I discovered a better compositional location, and taking advantage of a cloud covering the sun on the way back, I slipped back up the spur trail and shot this photo without the filter - I won't use it if I don't have to!
