I am always intrigued by desert plants and how they grow and bloom. The agave (above) grows from a tightly packed center. As the leaves peel outward, they retain the lines of the leaves they grew adjacent to. The plants provides great lines and textures and photograph well from many angles, but I always liked this one showing the core.
Bolts of lightning always leave fascinating lines, whether a single strike, or a multitude. This was probably the most potent and tightly concentrated thunderstorm I ever photographed.
Another weather situation that can provide great lines to photograph are icicles.
I’m always looking for trees to photograph, mostly based on their lines and the shapes they create.
Sometimes, I don’t even have to look upward to see the photograph I want from a tree. Ponderosa pines are one of many types of trees with great bark patterns.
I find that landscape photographs are often best when there are lines that take you through the frame. The southwestern US has many locations with powerful lines.
The canyons near Escalante, Utah streaked with desert varnish, or the twisted sandstone of the Vermillion Cliffs are just two examples of that.
