The composition techniques in photography are mere guidelines to help beginners capture eye-catching images. These provide a great starting point until an individual is able to outgrow them in capturing images through more advance techniques.
The golden triangle rule is a rule of thumb in visual composition for photographs or paintings, especially those which have elements that follow diagonal lines. The frame is divided into four triangles of two different sizes, done by drawing one diagonal from one corner to another, and then two lines from the other corners, touching the first ...
Related to the rule of odds is the observation that triangles are an aesthetically pleasing implied shape within an image. In a canonically attractive face, the mouth and eyes fall within the corners of the area of an equilateral triangle. [citation needed] Paul Cézanne successfully used triangles in his compositions of still lifes. A ...
One of the sensors is typically a digital camera device, and the other one can also be a camera or a light projector. The projection centers of the sensors and the considered point on the object's surface define a (spatial) triangle. Within this triangle, the distance between the sensors is the base b and must be known. By determining the ...
In some applications, it is desirable that the triangulation is independent of the coordinate system used to represent 3D points; if the triangulation problem is formulated in one coordinate system and then transformed into another the resulting estimate x est should transform in the same way.

Paradox illusions (or impossible object illusions) are generated by objects that are paradoxical or impossible, such as the Penrose triangle or impossible staircase seen, for example, in M. C. Escher's Ascending and Descending and Waterfall. The triangle is an illusion dependent on a cognitive misunderstanding that adjacent edges must join.
(In photography, the magnification is usually defined to be positive, despite the inverted image.) For example, with a magnification ratio of 1:2, we find f = 1.5 ⋅ F {\displaystyle f=1.5\cdot F} and thus the angle of view is reduced by 33% compared to focusing on a distant object with the same lens.
