Waimea translates from the Hawaiian language to "red (fresh) water". Given the island's high iron-content red soil, it's easy to see how the river water would flow red. Waimea Canyon is often referred to as the Grand Canyon of the Pacific, and its resemblance is clear. Constantly changing weather conditions make each visit a unique experience with rain and sunshine, dazzling colors, striking contrasts, moving light, and often rainbows. The images below were taking from a variety of vantage points on the ground and in the air. Some of these were taken only moments apart yet display very different conditions.

Na Pali means the cliffs, and Kauai's north shore is a gallery of them. What follows is a collection of images, including three stereograms, of many of these cliffs, taken from a helicopter and a boat.
Clear air and bright sunshine highlight the diverse colors of the scenery which vary dramatically depending on time of day, weather, sun and viewing angles, etc. The same scene from the same vantage point may appear very different through the course of a single day. Kauai's soils range in color from beige sandy beaches through deep coffee browns to intense Martian reds. Lush vegetation, clear ocean waters, and the deep blue sky add vivid greens and blues to the scene. Bright clouds gleam a striking white that can overwhelm the camera, often making it difficult to capture the full range of color and illumination in a single frame. As spectacular as some of these views may be, they don't come close to the experience in person. Two features of the Na Pali coast are the Kalalau Valley and Hanakapiʻai Beach. These appear in earlier posts on this blog and are omitted from this one. As usual, click on any image to see a larger version.

ים אדום של פרגים

Frequently people land on this site with search queries like "what part of the eye corresponds to the camera shutter". With a camera, the shutter opens for a very precise amount of time and allows light to hit the film or sensor inside the camera. The closest comparison to that in the eye would be the eyelid that can open and close but its purpose is more analogous to that of the lens cap than the shutter. Shutter mechanisms come in a variety of configurations. More detailed information about camera shutters can be found in this article [Wikipedia].
Camera lenses also have a diaphragm iris [Wikipedia] which adjusts to increase or decrease the amount of the available light that can pass through it during any given period of time. This corresponds directly to the iris in the eye [Wikipedia] which serves the same purpose. I suspect many people confuse this with the diaphragm-type shutter mechanism, however both the eye's iris and that of the camera are visible through the lens while the shutter is generally inside the camera and out of sight. In modern cameras, the iris is usually fully open except at the moment when a picture is taken so it can be seen to move right about the same time as the shutter.
