Dual Aperture Series: Saddlebag Lake Pines (Sony A7R)

This pair of aperture series is intended to show the differing visual impacts and associated tension created by relative illumination (vignetting), depth of field (sharp/unsharp), and motion blur (wind/water). All three effects combine and in effect are a sort of mini slide show

See the discussion on the complex nature of these seemingly simple images, particularly as series for two similar but quite different compositions. The interplay of elements across the series is thought provoking as to which combination one might choose in the field, and also shows that making only one image variant can be a mistake under rapidly changing conditions.

These series were taken at late dusk, dark to the point where it was becoming hard to see the trail as I hiked out. The wind was whipping violently across the lake (and me, clad in dual down jackets), creating interesting light/dark patterns. In such conditions it is wise to block the worst of the buffeting by standing appropriately near the camera.
