Lenticular printing is a technology in which lenticular lenses (a technology also used for 3D displays) are used to produce printed images with an illusion of depth, or the ability to change or move as they are viewed from different angles. Examples include flip and animation effects such as winking eyes, and modern advertising graphics whose ...
A lenticular lens is an array of lenses, designed so that when viewed from slightly different angles, different parts of the image underneath are shown. [ 1 ] [ 2 ] [ failed verification – see discussion ] The most common example is the lenses used in lenticular printing , where the technology is used to give an illusion of depth, or to make ...
In some lenses, the curved surfaces are replaced with flat surfaces, with a different angle in each section. Such a lens can be regarded as an array of prisms arranged in a circular fashion with steeper prisms on the edges and a flat or slightly convex center. In the first (and largest) Fresnel lenses, each section was actually a separate prism.
Lenticular fabric. An example of a lenticular fabric sheet that changes from a blue background with white stars to a white background with red stars. A lenticular fabric is a lattice-like arrangement of lens-shaped materials formed into a thin layer. [1] When the surface of the fabric is smooth, it often has a reflective and light-distorting ...
Sega Nintendo Fujifilm. Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called " glasses-free 3D " or " glassesless 3D ".
Barrier-grid animation or picket-fence animation is an animation effect created by moving a striped transparent overlay across an interlaced image. The barrier-grid technique originated in the late 1890s, overlapping with the development of parallax stereography ( Relièphographie) for 3D autostereograms. The technique has also been used for ...
In a multiple-lens system, each lens treats the previous lens's image as an object, and produces a new image of it, so that the imaging is cascaded through the lenses. This is easy to understand when the image from one lens is before the front focus of the next lens, but it remains true even when the intermediate image is located within the ...
Most of the photographs I have seen from Denali and Alaska in general use very long lenses. Nikon has a 1.5 crop factor compared to the Canon's 1.6 so a little longer will only help you. I have to disagree that having very long lenses in Denali will really help you especially in Denali. A 500mm lens vs. a 300mm lens really isn't all that great ...
