It is difficult to photograph the complete semicircle of a rainbow in one frame, as this would require an angle of view of 84. For a 35 mm camera, a wide-angle lens with a focal length of 19 mm or less would be required. Now that software for stitching several images into a panorama is available, images of the entire arc and even secondary arcs can be created fairly easily from a series of overlapping frames.

Droplets (or spheres) composed of materials with different refractive indices than plain water produce rainbows with different radius angles. Since salt water has a higher refractive index, a sea spray bow doesn't perfectly align with the ordinary rainbow, if seen at the same spot.[63] Tiny plastic or glass marbles may be used in road marking as a reflectors to enhance its visibility by drivers at night. Due to a much higher refractive index, rainbows observed on such marbles have a noticeably smaller radius.[64] One can easily reproduce such phenomena by sprinkling liquids of different refractive indices in the air, as illustrated in the photo.

The driver does not make use of the hardware chip select lines because of some limitations - instead it can use an arbitrary number of GPIOs as software/GPIO chip selects. This means you are free to choose any spare GPIO as a CS line, and all of these SPI overlays include that control - see /boot/overlays/README for details, or run (for example) dtoverlay -h spi0-2cs (dtoverlay -a grep spi might be helpful to list them all). 2ff7e9595c
