A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4][5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...
Communication is irreversible in the sense that the effects it has on the communicators cannot be undone. In this regard, communication influences and changes the participants in various ways. So after a conversation, there is usually no way to go back and restore the state of the communicators prior to it.
This makes the process more complicated since each participant acts both as sender and receiver. For many forms of communication, feedback is of vital importance, for example, to assess the effect of the communication on the audience. [17] [12] However, it does not carry the same weight in the case of mass communication. Some theorists argue ...
A wide range of fish species has developed and maintained this visual trait throughout evolution, suggesting it is advantageous. UV vision may be related to foraging, communication, and mate selection. The leading theory regarding the evolutionary selection of UV vision in select fish species is due to its strong role in mate selection.
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
Fishbowl (conversation) The arrangement of chairs in a fish bowl session. Four concentric rings of chairs surround a smaller group of five chairs. An arrow indicates how any member of the audience may enter the middle section. A fishbowl conversation is a form of dialogue that can be used when discussing topics within large groups.
In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the edges of walls of buildings, appear with straight lines, as opposed to being curved. In other words, it is a lens with little or no barrel or pincushion distortion. At particularly wide angles, however, the rectilinear perspective ...
Facial expression. A facial expression is one or more motions or positions of the muscles beneath the skin of the face. These movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication. They are a primary means of conveying social information between humans, but they also occur ...
