When the sky is clear at sunrise/sunset, there are some expected parameters for landscape photography. One is that the first/last light will be very warm in color and another is that pastel colors will show in earth shadow and the Belt of Venus above it low in the sky opposite the rising/setting sun. These two parameters combine very nicely.
I don't always require myself to use a completely level camera (tilt and roll) for landscape photography but did so in this case, primarily to keep the sides of the lighthouse from leaning. Adding to that compositional constraint was the desire to have the reflections availed by the foreground tidal pool included in the frame. The lighthouse reflection was the primary interest and it was very tightly framed between the surrounding rocks, further limiting the camera position to within that narrow line. With the rocks being indicative of the Maine coastline, having them close and emphasized seemed logical and led to this final camera position.
Should circular polarizer filters be used for all landscape photographs? While CPL filters are easily my most-used filters and I very frequently use them for landscape photography, this was a time when using the effect provided by this filter was a detriment to the final look. Cutting the reflections on the rocks and in the tidal pool created a dark, flat, lifeless look to the foreground rocks and water, detracting significantly from the result. It didn't take long to determine which look was preferable.
Wet dark-colored rocks absorb a lot of light even without a CPL filter and two exposures were combined to ensure that details were retained in those rocks in the final image.
