Description

A unique, lesser-seen technique for prisms in photography is using these reflections to create leading lines! With prisms’ ability to reflect, use this to your advantage to draw attention to your subject. You can even work in some symmetry, too.

The lens I used was very pre-production and I couldn’t get to use SeeDeep myself, but even in with these limitations I was able to get an idea of the effects that can be created, and the relative ease with which they can be achieved. The K-Lens certainly has promise and I look forward to seeing what photographers in the field can create with it. Once this one is off the ground it will be interesting to see what other focal lengths the company will offer, and how the technology will develop. I have been told that K-Lens hopes to be able to integrate ND filters into the mirror tunnel to enable one-shot HDR imaging by recording a wide range of exposures in a single shot - which would be another useful feature. Polycentral Kaleidoscope" with three reflectors at angles of 90°, 60° and 30°: the pattern with 31 reflected images of the aperture, not symmetrically arranged around the centre. Brewster deemed the effect "very beautiful, particularly when the reflectors are metallic". [7] Kohler, Kevin. "Frequently Asked Questions." KaleidoscopeCollector.com. (Jan. 12, 2012) http://www.kaleidoscopecollector.com/faq.htmlBush, Charles. "Improvement to Kaleidoscopes." September 30, 1873. (July 28, 2011) http://www.brewstersociety.com/bush_patent.pdf Evidence shows that pieces of polished obsidian (a volcanic glass) were used as mirrors as long as 8,000 years ago [source: Enoch]. Mirrors reflected sunlight or fire in early lighthouses, and there's a record of a possible optical illusion by an ancient Egyptian magician involving a mirror. By the 17th century, the "Hall of Mirrors" -- an ornate corridor with 357 mirrors -- in the Palace of Versailles became a display of French glory. Mirrors also may have helped achieve symmetry in planning ornamental gardens, a step in the direction toward the kaleidoscope. Prisms are used in many optical devices, including cameras, binoculars, and telescopes. The design and construction of a prism depend on its intended use. For example, a prism used in a camera lens needs to be small and lightweight, while a prism used in a telescope needs to be large and sturdy. Kaleidoscope technology made its next leap forward in 1873. That's when American Charles Bush patented several improvements. He added a stand that could be easily disassembled for portability and a rotating wheel to expand the variety of possible designs. Perhaps Bush's most ingenious advance, though, came in the form of special ampoules. An ampoule is a small, sealed glass vial often holding medicine. Tiny ampoules already had been used as objects in some kaleidoscopes. Bush's patent specified ampules with "two or more liquids of different densities or character, or a liquid with a solid or solids." Bush wrote that the liquids within the ampoules should be unable to mix and each would have its own color. This allowed for even more intricate designs [source: Bush].

Brewster Kaleidoscope Society. "Sequence of Reflection Diagrams." (Jan. 12, 2012) http://www.brewstersociety.com/mirrors.html#sequence The creative possibilities of the K|Lens One are endless: depth-based editing, focus pulls, re-focusing, extended depth of field and simplified segmentation are just the beginning. K|Lens One photos and videos are also a perfect match for all 3D displays, be it stereo, holographic, or light field. In addition, light-field content can be integrated into web applications to provide for a vivid and lively user experience. On top of that, users always have access to multiple perspectives of their scenes to create with.The second method will find you holding the prism away from your lens and placing it between the light source and your subject. The prism will serve as a sort of GOBO and cast colorful lights on your subject. It’s another way to add off-camera lighting effects to your portraiture, albeit a slightly unpredictable one. The light source can be natural or artificial. The important part is getting the angle of the prism just right. Expect to work through some trial and error before you get it right. Prism Photography Tip #7: Create a Kaleidoscope Effect with Your Smartphone Camera Photos courtesy of SLR Lounge Strathmore. "About Strathmore - History." (Jan. 11, 2012) http://www.strathmore.org/aboutstrathmore/history/fineartshistory.asp a wide variety of objects, small figures, fragments, liquids and materials of different colors and shapes can be used in object cells (apart from the more usual transparent fragments, for instance twisted pieces of iron or brass wire, or some lace, can produce very fine effects) [7] The K-Lens is constructed in three distinct sections that can be seen clearly from the outside. The fromt part of the lens is of a regular 80mm optical construction, but when the light passes through it enters the second section of the lens—the mirror tunnel, which sits were the sensor in a normal array would be. Instead of hitting the sensor though, the focused light meets a series of mirrors in the tunnel that are positioned at different angles to allow each a slightly different view of the subject. The mirrors, along with the light that passes directly through the tunnel, create nine individual images that go on to pass through the rear section of the lens to the camera’s sensor. The result is a grid of nine pictures in a variety of orientations, all recorded on a single frame. The effect is akin to looking through a kaleidoscope—hence the name ‘K-Lens’. The company says devices such as the Lume Pad and Looking Glass displays also work well with images recorded using the K-Lens, and 3D effects can be viewed using Google’s Cardboard. Relief printing, where the image is printed in 3D, is also an application, as is lenticular printing. In use

When it comes to camera compatibility, it's important to ensure that the lens adapter is compatible with your camera's lens mount. There are various mounting options available, including screw-on adapters, bayonet mounts, and magnetic mounts.Items that fit in the holder. There are no rules here, although things like confetti, beads and ribbon are a good place to start. variations in the angle of inclination of the reflecting surfaces. In his patent Brewster deemed 18°, 20° or 22 1/2° most pleasing. [6] In the treatise 45°, 36° and 30° are the primary examples. [7] placement of "regularly crystallised bodies or pieces of glass that have received the polarising structure" in front of the aperture, to introduce "the complementary colors of polarised light" [6] Looking through the viewfinder we are presented with a kaleidoscopic view of the scene in front of the lens. This makes focusing and composition quite hard, so we need to magnify the view until one of the nine images fills the finder – the image at the top left is in the correct orientation. An alternative is to use the optional HDMI monitor provided by K-Lens which displays this part of the image by default. When looking for a high quality prism, you want it to be made of glass, and free of bubbles for the cleanest possible images.
