First, I'll show two photos with the spider. Although it is hard to believe, these are the actual colors created by diffraction as the early morning light hit the spider web!
Next is a series of close-ups of the strands in the center of the web, some of which are shown in the photos above. [You can click on the images for larger versions.]
In one photo I captured some of the strands directly adjacent to the spider. Eric calls this image "The Silk Road." The diversity of colors is amazing.
I can't help sharing one more series. This morning I focused on one section of one particular thread. Its appearance changed, likely depending on when I took the picture and the camera settings. Remember, this entire series (below) is of the same thread (!). There are so many colors in these pictures, that I started wondering — if you kept photographing spider webs, could you discover new shades of colors?
Spending time with these spiders and their silk strands has certainly been inspiring and enlightening for me! :)
