A snapshot is a casual photograph taken without any particular
pre-arrangement, often of everyday events or sightseeing excursions.
Snapshots are often imperfect or considered amateurish and may be out of
focus or poorly framed or composed. However, snapshots document moments
in life more "truthfully"; that is, the photos tend to be more
spontaneous and unstaged.
The snapshot concept was introduced to the public on a large scale by
Eastman Kodak and its Brownie box camera around 1900. Kodak encouraged
families to buy the Brownie to capture a moment in time, and to not be
concerned with shooting a perfect image. Kodak advertising encouraged
consumers to "celebrate the moments of your life" and find a "Kodak
moment."
The "snapshot camera" tradition continues with inexpensive
point-and-shoot digital cameras that fully automate flash, ISO, focus,
shutter speed, and other functions, making the shooting of a
good-quality image simple. Such cameras are typically programmed to
achieve a deep depth of field and high shutter speed so that as much of
the image is in focus as possible.
For expert photographers, who are better able to control the focus point, the use of shallow depth of field often achieves more pleasing images by blurring the background and making the subject stand out.
Laughter is an audible expression or appearance of merriment or amusement or an inward feeling of joy and pleasure(laughing on the inside).
It may ensue (as a physiological reaction) from jokes, tickling and other stimuli.
Inhaling nitrous oxide can also induce laughter; other drugs, such as cannabis, can also induce episodes of strong laughter.
Strong laughter can sometimes bring an onset of tears or even moderate muscular pain as a physical response to the act.
Laughter can
also be a response to physical touch, such as tickling, or even to
moderate pain such as pressure on the ulnar nerve ("funny bone").
Laughter is a part of human behavior regulated by the brain. It helps
humans clarify their intentions in social interaction and provides an
emotional context to conversations. Laughter is used as a signal for
being part of a group — it signals acceptance and positive interactions.
Laughter is sometimes seemingly contagious, and the laughter of one
person can itself provoke laughter from others. This may account in part
for the popularity of laugh tracks in situation comedy television shows.
The study of humor and laughter, and its psychological and physiological
effects on the human body is called gelotology.
Friendship is a term used to denote co-operative and supportive behavior between two or more humans.
This article focuses on the notion specific to interpersonal relationships. In this sense, the term connotes a relationship which involves mutual knowledge, esteem, and affection.
Friends will welcome each other's company and exhibit loyalty towards each other, often to the point of altruism.
Their tastes will usually be similar and may converge, and they will share enjoyable activities. They will also engage in mutually helping behavior, such as exchange of advice and the sharing of hardship.
A friend is someone who may often demonstrate reciprocating and reflective behaviors.
Yet for many, friendship is nothing more than the trust that someone or something will not harm them.
Value that is found in friendships is often the result of a friend demonstrating on a consistent basis:
* the tendency to desire what is best for the other,
* sympathy and empathy,
* honesty, perhaps in situations where it may be difficult for others to
speak the truth, especially in terms of pointing out the perceived
faults of one's counterpart, and
* mutual understanding.
