Word Press Weekly Photo Challenge this week is to present photos showing “lines.”  

These photos all contain lines that slant together with lines that are straight, which is how I selected photos for this challenge.

Fences create slanting lines when viewed head on – they lead to a hypothetical vanishing point.  This is called one-point perspective, a basic technique used in drawing and photography.  Below, a fence in León, Nicaragua followed by a fence in Des Plaines.

Buildings also offer excellent opportunity for juxtaposed slanting and straight lines using one-point perspective, such as the outside of the Des Plaines Library and …
a hallway at Writers’ Theatre in Glencoe, Illinois.and a row of chairs in that same theatre. (A few curves, too, since not all the chairs fold up uniformly!)

Nature combined with man-made structures offers another opportunity to photograph slanted and straight lines.  This photo shows the contours of nature in the trees, and how they have been cut to accommodate telephone wires.
