In various images he manages to convey a sense of alternating light and space, even movement — especially as shadows and slivers of natural light from nearby windows rake across the ink.
The six replicates were kept under alternating light and dark conditions.
These beams form a pair of alternating light fields for stereo 3-D view.
In the insects placed on alternating light-dark cycles, the activity fluctuated with the changing light conditions.
It contains a distinct lamination, consisting of alternating light- and dark red/brown layers that are 1 2 mm in thickness.
Newton's ring interference fringes is composed of alternating light and dark stripes, and light and dark area are clear, as shown in Fig. 2(a).
