'''Forced perspective''' is a technique used in film, photography and other art that alters perceived object size and distance. The technique takes advantage of the visual cues humans use to perceive depth such as angular size, aerial perspective, shading, and relative size. Using tools to counter and manipulate these cues, artists can move the visual plan of an object at will.
 
==Angular size==
Consider two objects of equal size placed at different distances from an audience. Increasing the object's distance from the audience makes the object appear smaller, its apparent size decreases as distance from the audience increases. This phenomenon is that of the manipulation of angular and apparent size.
 
A person perceives the size of an object based on the size of the object's image on the retina. This depends solely on the angle created by the rays coming from the topmost and bottommost part of the object that pass through the center of the lens of the eye. the larger the angle an object subtends, the larger the apparent size of the object. The subtended angle increases as the object moves closer to the lens. Two objects with different actual size have the same apparent size when they subtend the same angle. Similarly, two objects of the same actual size can have drastically varying apparent size when they are moved to different distances from the lens.<ref>Knight, Randall Dewey., Brian Jones, and Stuart Field. College Physics: a Strategic Approach. 1st ed. San Francisco: Pearson Education, 2006. Print. p. 704-705.</ref>
 
===Calculating angular size===
[[File:Angular Size.jpg|thumb|alt=Angular Size depiction.|Angular Size, distance and object size.]]
The formula for calculating angular size is as follows:
:<math>\theta=2\tan^{-1}\left(\frac{h}{2D}\right)</math>
 
in which ''θ'' is the subtended angle, ''h'' is the actual size of the object and ''D'' is the distance from the lens to the object.<ref>Michael A. Seeds; Dana E. Backman (2010). Stars and Galaxies (7 ed.). Brooks Cole. p. 39.</ref>
 
==Manipulating perspective in art==
Humans use a variety of techniques beyond angular size to perceive depth. In film, photography and art, perceived object distance is manipulated by altering fundamental monocular cues used to discern the depth of an object in the scene such as aerial perspective, blurring, relative size and lighting.
 
Using these other monocular cues in concert with angular size, the eyes can perceive the distance of an object. Artists are able to freely move the visual plane of objects by obscuring these cues to their advantage.
 
===Techniques employed===
*Solely manipulating angular size by moving objects closer and farther away cannot fully trick the eye. Objects that are farther away from the eye have a lower luminescent contrast due to atmospheric scattering of rays. Fewer rays of light reach the eye from more distant objects. Using the monocular cue of aerial perspective, the eye uses the relative luminescence of objects in a scene to discern relative distance. Filmmakers and photographers combat this cue by manually increasing the luminescence of objects father away to equal that of objects in the desired plane. This effect is achieved by making the more distant object more bright by shining more light on it. Because it is known that luminance decreases by ½''d'' (''d'' is distance from the eye), artists can calculate the exact amount of light needed to counter the cue of aerial perspective.<ref>O'Shea, R.P., Blackburn, S.G., & Ono, H. (1994). Contrast as a depth cue. Vision Research, 34, 1595–1604.</ref>
*Similarly, blurring can create the opposite effect by giving the impression of depth. Selectively blurring an object moves it out of its original visual plane without having to manually move the object.<ref>George Mather (1996) "Image Blur as a Pictorial Depth Cue". Proceedings: Biological Sciences, Vol. 263, No. 1367 (Feb. 22, 1996), pp. 169–172.</ref>
*A perceptive illusion that may be infused in film culture is the idea of Gestalt psychology, which holds that people often view the whole of an object as opposed to the sum of its individual parts.<ref>{{cite web|title = Gestalt Psychology|url=http://webspace.ship.edu/cgboer/gestalt.html|accessdate=5 March 2013}}</ref>  
* Another monocular cue of depth perception is that of lighting and shading. Artists also use lighting to establish shadows. Shading in a scene or on an object allows the audience to locate the light source relative to the object. Making two objects at different distances have the same shading gives the impression that they are in similar positions relative to the light source, and therefore, they are apparently much closer than they are in actuality.<ref>Lipton, L. (1982) Foundations of the Stereoscopic Cinema - A Study in Depth. New York, Van Nostrand Reinhold, pg 56.</ref>
*A simpler technique employed by artists is that of manipulating relative size. Once the audience becomes acquainted with the size of an object in proportion to the rest of the objects in a scene, a photographer or filmmaker can replace the object with a larger or smaller replica to change another part of the scene's apparent size. This is done frequently in movies. For example, to aid in the appearance of a person as a giant next to a "regular sized" person, a filmmaker might have a shot of two identical glasses together, then follow with the person who is supposed to play the giant holding a much smaller replica of the glass and the person who is playing the regular-sized person holding a much larger replica. Because the audience has seen that the glasses are the same size in the original shot, the difference in relation to the two characters allows the audience to perceive the characters as different sizes based on their relative size to the glasses they are holding.<ref name="Purves">Purves D, Lotto B (2003) ''Why We See What We Do: An Empirical Theory of Vision''. Sunderland, MA: Sinauer Associates.</ref>
*A monocular cue easily taken advantage of by painters is the trend for the color of objects in the distance to be shifted more towards the blue end of the spectrum, while closer objects' colors are shifted toward the red end of the spectrum. A painter can give the illusion of distance by adding blue or red tinting to the color of the object he is painting.<ref name="Purves"/>
 
===Examples of forced perspective===
====In film====
Most recently, forced perspective has been employed to create dwarfs and giants in film series such as [[Harry Potter]] and [[The Lord of the Rings]]. For example, the Hobbit Frodo in the Lord of the Rings, and Hagrid the half-giant in Harry Potter.
 
In reality, there is only a 5-inch height difference between the two actors, Frodo being 5′6″ and Gandalf being 5′11″, but the altered angular size of the actors allows for a much more drastic difference.
 
Consider this photo of Harry Potter ([[Daniel Radcliffe]], 5′5″) and Rubeus Hagrid ([[Robbie Coltrane]] 6′1″). Forced perspective techniques allow for the illusion that Hagrid is much larger than Harry in the movie than he is in reality.
 
====In art====
In his painting entitled ''Still life with a curtain'', [[Paul Cézanne]] creates the illusion of depth by using brighter colors on objects closer to the viewer and dimmer colors and shading to distance the "light source" from objects that he wanted to appear farther away. His shading technique allows the audience to discern the distance between objects due to their relative distances from a stationary light source that illuminates the scene. Furthermore he uses a blue tint on objects that should be farther away and redder tint to objects in the foreground.
 
====In photography====
Consider this photo that utilizes the technique of forced perspective to place a man into a coffee cup. Manipulating angular size allows the man to appear small enough to fit in the coffee cup. This is done by placing the coffee cup much closer to the camera than the man is to the camera.
 
The shading and shadows have been manipulated to make the two objects appear to be the same distance from the light source. They also appear to have the same orientation to the shared light source. This has been achieved by using multiple light sources to alter shadows and luminescence. Increasing the luminescence of the man counteracts the dimming effect of increased distance.
 
Finally, the man and the cup have a very similar level of focus/blur, meaning that they are brought into the same visual plane.

When you make improvements to your home you are not only creating beautiful upgrades to your home's environment, but you are also increasing its overall when and if you decide to sell in the future. If you will follow these tips, you can make valuable and cost-efficient enhancements to your home.

A nice addition to any home is a nicely crafted fence. If your home is lacking a fence, you might decide it is time to build one. Fences look great in just about any home and can help raise the property value of your home. You can also feel a little more secure, as having a fence can help keep random strangers off your property.

You can find many articles and web pages online that can give you tips when remodeling your home. A quick search on the internet can go a long way, and it doesn't hurt to gain more knowledge. You want to make sure you tackle each project with confidence before you start it. You might finish the job quicker too, if you do just a little research.

Do not buy furniture that is upholstered with strong patterns. Buying these items with geometric shapes, patterns, and floral prints may already decide what the home decor has to look like. Purchase furniture in solid, basic colors such as tan, black, blue, brown and green. In this way, you can change accessories frequently for a fresh new look. Pattern can be introduced through pillows, throws and other items.

Carpet the bottoms of the drawers you keep your hand tools in. This will not only make the shop room a quieter place but it will help protect your valuable tools. Keep those tools rust free by spraying the carpet lightly with machine oil before you place the tools inside the drawer.

There are a few ways to deal with screws that are too tight or too loose in your home. Use clear nail polish to tighten screws that are too loose. To loosen screws that are too tight, try adding peroxide or ammonia, letting them soak for just a few minutes before attempting to unscrew.

If you don't want to invest money into buying a slipcover for your chair, you can make your own from a bed sheet. Buy a twin or queen-size bed sheet from cotton in the color of your choice. Drape it over your chair, and affix it with safety pins in a fashion that isn't noticeable.

Maximize kitchen cabinet storage space. Use a turntable inside a cabinet for smaller items such as spice jars. In larger cabinets, use shelf dividers to double the storage space. Stack items on top of each other, such as canned or boxed food goods. Install floor to ceiling pantry cabinets. The most important tip? Get rid of anything you don't need or use, such as old appliances or tableware. Any food that you don't intend to eat, especially canned items, can be donated to your local food bank.

A lot of homes have wall to wall carpeting that is stained and looks bad. Wood floors offer lasting appeal and more durability than carpeting can offer.

If you have bought a home in an undeveloped area, or in the midst of a wooded area, consider installing a quality fence around the boundaries of your property. This will help keep the wild animals out of your yard and your garden if you have one.

Most people don't think of their circuit breakers until they lose power unexpectedly. One of the best things you can do to improve the safety and efficiency of your home is to regularly test your breakers by switching them on and off at least once yearly. This clears the breaker contacts of any built-up corrosion and allows them to work more efficiently and safely. If your breakers frequently trip, this may indicate potential safety issues that require an electrician.

Many times contractors lower construction costs by using solid wood cabinets with no hardware. Hardware stores in your area are sure to carry a variety of pulls and knobs, so you won't have any problem finishing off the look. You can choose from designer accents, pulls that have a vintage look or modern knobs which can be put in place in minutes.

Do-it-yourself projects aren't just for professionals or the highly skilled, everyone has some talent. It's something anyone could do. A simple coat of paint or a kitchen remodeling can create comfort and add value to any home. Apply the information from this article above and get started with your home improvement project planning today.
