They wanted to put close-up, macro and micro photography on the center stage and be celebrated in its own right.Tracy, a former editor of Outdoor Photography and a features editor at Amateur Photography, has over 20 years experience in the photo magazine industry. She’s also a photography instructor at West Dean College in Sussex, and an author of Close-up & Macro Photography, which has been translated into French and Chinese. Dan is a contributor to Black + White Photography magazine.This year’s Close-up Photographer of the Year (CUPOTY 03) has more than 9000 photos from 55 countries across nine different categories.

Spider Demonstrates How to Build a WebHave you ever considered how much engineering talent goes into building a website? I mean, a spider web? An orb-weaving spider must deal with a crushing schedule, two kinds of materials, design decisions, and the laws of physics. From Wikipedia: Generally, orb-weaving spiders are three-clawed builders of flat webs with sticky spiral capture silk. The building of a web is an engineering feat, begun when the spider floats a line on the wind to another surface. The spider secures the line and then drops another line from the center, making a "Y". The rest of the scaffolding follows with many radii of nonsticky silk being constructed before a final spiral of sticky capture silk.The third claw is used to walk on the nonsticky part of the web. Characteristically, the prey insect that blunders into the sticky lines is stunned by a quick bite, and then wrapped in silk. If the prey is a venomous insect, such as a wasp, wrapping may precede biting and/or stinging. Much of the orb-spinning spiders' success in capturing insects depends on the web not being visible to the prey, with the stickiness of the web increasing the visibility and so decreasing the chances of capturing prey. This leads to a trade-off between the visibility of the web and the web's prey retention ability.[4]Many orb-weavers build a new web each day. Most orb-weavers tend to be active during the evening hours; they hide for most of the day. Generally, towards evening, the spider will consume the old web, rest for approximately an hour, then spin a new web in the same general location. Thus, the webs of orb-weavers are generally free of the accumulation of detritus common to other species, such as black widow spiders. Now watch that all come together in this fascinating time-lapse video.
