The slats of a mini blind. A mini blind is a type of horizontal window blind made of long, narrow slats held together by string. Its slats are less than half the width of a regular venetian blind, and are often made of aluminium, measuring 15 millimetres (0.59 in) or 25 millimetres (0.98 in).
Various window blind styles. A window blind is a type of window covering. [1] There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats.
Piston and tilt are not actually true optical aberrations, as they do not represent or model curvature in the wavefront. Defocus is the lowest order true optical aberration. If piston and tilt are subtracted from an otherwise perfect wavefront, a perfect, aberration-free image is formed. Rapid optical tilts in both X and Y directions are termed ...
The TS-E 17 mm f / 4L provides four degrees of freedom, allowing ±6.5° tilt with respect to the film or sensor plane and ±12 mm shift with respect to the center of the image area; each movement can be rotated ±90° about the lens axis.
The mechanisms providing the tilt and shift functions can be rotated 90° to the left or right so that they operate horizontally, vertically, or at intermediate orientations. The lenses are supplied with the tilt and shift movements at right angles to each other; they can be modified by Nikon so that the movements operate in the same direction.
Psychophysics experiments have shown that relative orientations between 0 deg and about 50 deg produce repulsion effects (the test line or grating tends to rotate away from the contextual stimulus), which is known as the direct form of the tilt effect; but larger relative orientations up to 90 deg produce attraction effects (the test line or ...
