AuthaGraph. This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles.

Mercator map

Mercator maps distort the shape and relative size of continents, particularly near the poles. This is why Greenland appears to be similar in size to all of South America on Mercator maps, when in fact South America is more than eight times larger than Greenland.

There are four main types of distortion that come from map projections: distance, direction, shape and area. The Mercator projection, for example, distorts Greenland because of its high latitude, in the sense that its shape and size are not the same as those on a globe.

A map projection is a mathematical formula used to transfer all or part of the curved surface of the earth onto the flat surface of a map. The process of flattening the earth causes distortions in one or more of the following spatial properties: Distance. Area.

There are four main types of distortion that come from map projections: distance, direction, shape and area.

A map that preserves shape is conformal. Even on a conformal map, shapes are a bit distorted for very large areas, like continents. A conformal map distorts area—most features are depicted too large or too small. The amount of distortion, however, is regular along some lines in the map.

A melted crayon, a deflated balloon, a CD or DVD with scratches that no longer plays correctly — these things have all been affected by distortion. Other examples of distortion are things like your reflection in a broken mirror or the sound of your voice underwater.

These characteristics include distance, direction, shape, and area. The only place on a map where there is no distortion is along the trace of the line that marks the intersection of our ‘paper’ with the surface of the earth. Any place on the map that does not lie along this line will suffer some distortion.

1 : the act of twisting or altering something out of its true, natural, or original state : the act of distorting a distortion of the facts. 2 : the quality or state of being distorted : a product of distorting: such as.

to destroy something by twisting it with force or tearing it into pieces so that its original form is completely changed: My sweater got mangled in the washing machine.

transitive verb. 1 : to induce magnetic properties in. 2 : to attract like a magnet : charm.

A distortion is a change, twist, or exaggeration that makes something appear different from the way it really is. You can distort an image, a thought, or even an idea. The heat creates a wavy distortion in the air that shakes up the image of the things beyond it.

Manually correct image perspective and lens flaws

1. Choose Filter > Lens Correction.
2. In the upper-right corner of the dialog box, click the Custom tab.
3. (Optional) Choose a preset list of settings from the Settings menu.
4. Set any of the following options to correct your image.

While optical distortion is caused by the optical design of lenses (and is therefore often called “lens distortion”), perspective distortion is caused by the position of the camera relative to the subject or by the position of the subject within the image frame.

As distortion is caused by the effects of perspective on the lens, the only way to correct for barrel lens distortion in-camera is to use a special “tilt and shift” lens, which is designed for architectural purposes. However, these lenses are costly, and only really make sense if you specialize in this field.

This can correct certain things that make the image look curved too outward or inward. The best feature is the Remove Distortion slider, which you can adjust. To correct barrel distortion, move the Remove Distortion slider to the right. To correct pincushion distortion, adjust the slider to the left.

The good news is it’s usually fixable in post processing and can even be desirable! Lens distortion is an important factor to be aware of in the photography world. It can make or break our images as artists, depending on the look and feel we are trying to achieve.
