–This is a composite– I’ve seen a trend lately where photos that are obviously composites are shared around the web and when the photographer is questioned about the photograph they refuse to reveal the truth about the photo. Not here - these are two images merged into one for artistic effect. If you like it, share it…comments and critiques are more than welcome. Facebook | Web | 500px

Spirit Mountain Sunset, by spirepress

This is a multilayer composite consisting of 7 major layers. The sky is a Colorado sunset. El Capitan is near the Arizona Utah border. The foothill and trees are north of Fort Collins, CO. The background mountains are the Snowy Range in Wyoming, and the bluffs are near Casper, WY. The prairie in near the Badlands in South Dakota, and the foreground flowers are a mix from various places. I wanted my spirit mountain to stand out in a new setting.

5 things you didn’t know about…spider silk

1. Spider silk is a protein fibre. Spiders use their silk to make webs or other structures, which function as nets to catch other animals, or as nests or cocoons to protect their offspring.

2. Spider dragline silk has a tensile strength of roughly 1.3 GPa.

3. Dragline silk is a composite material comprised of two different proteins, each containing three types of regions with distinct properties. One of these forms an amorphous (noncrystalline) matrix that is stretchable, giving the silk elasticity.

4. At one time, it was common to use spider silk as a thread for crosshairs in optical instruments, such as those in telescopes, microscopes, and telescopic rifle sights.

5. Silk can be formed into other shapes and sizes such as spherical capsules for drug delivery, cell scaffolds and wound healing, textiles, cosmetics and coatings.
