Hi, Alain,
The problem for an amateur is that he/she has no reason to take a photograph.
I'd like to start a discussion on the subject of amateurs vs professionals.
Well, they have special golf tournaments for that.
I thought this quote was a good place to start.
Well, I'd hate to start anything on a premise as silly as that.
Of course, Terence Donovan, being (at the time of his death) assumedly a "professional photographer", is not at all qualified to opine on the motivations of amateur photographers.
From Wikipedia
Professional
A professional is a person who is engaged in a certain activity, or occupation, for gain or compensation as means of livelihood; such as a permanent career, not as an amateur or pastime. The traditional professions were doctors, engineers, lawyers, architects and commissioned military officers. Today, the term is applied to nurses, accountants, educators, scientists, technology experts, social workers, artists, librarians (information professionals) and many more.
The term is also used in sports to differentiate amateur players from those who are paid—hence "professional footballer" and "professional golfer". Many companies include the word professional in their store name to imply the quality of their workmanship or service.
In some cultures, the term is used as shorthand to describe a particular social stratum of well-educated, salaried workers who enjoy considerable work autonomy and are commonly engaged in creative and intellectually challenging work.
Due to the personal and confidential nature of many professional services, and thus the necessity to place a great deal of trust in them, most professionals are subject to strict codes of conduct enshrining rigorous ethical and moral obligations.
Amateur
An amateur (French amateur "lover of", from Old French and ultimately from Latin
amatorem (nom.
amator), "lover") is generally considered a person attached to a particular pursuit, study, or science in a non-professional or unpaid manner. Amateurs often have little or no formal training in their pursuits, and many are autodidacts (self-taught).
Amateurism can be seen in both a negative and positive light. Since amateurs often do not have formal training, some amateur work may be considered sub-par. For example, amateur athletes in sports such as basketball, baseball or football are regarded as having a lower level of ability than professional athletes. On the other hand, an amateur may be in a position to approach a subject with an open mind (as a result of the lack of formal training) and in a financially disinterested manner. An amateur who dabbles in a field out of casual interest rather than as a profession or serious interest, or who possesses a general but superficial interest in any art or a branch of knowledge, is often referred to as a dilettante.
The lack of financial benefit can also be seen as a sign of commitment to an activity; and until the 1970s the Olympic rules required that competitors be amateurs. Receiving payment to participate in an event disqualified an athlete from that event, as in the case of Jim Thorpe. In the Olympics, this rule remains in place for boxing.
Many amateurs make valuable contributions in the field of computer programming through the open source movement. Amateur dramatics is the performance of plays or musical theater, often to high standards, but lacking the budgets of professional West End or Broadway performances. Astronomy, history, linguistics, and the natural sciences are among the myriad fields that have benefited from the activities of amateurs. Charles Darwin and Gregor Mendel were amateur scientists who never held a position in their field of study. William Shakespeare and Leonardo da Vinci were considered amateur artists and autodidacts in their fields of study.
Radio astronomy was founded by Grote Reber, an amateur radio operator; radio itself was greatly advanced if not founded by Guglielmo Marconi, a young Italian gentleman who started out by tinkering with a coherer and a spark coil as an amateur electrician. Pierre de Fermat was a highly influential mathematician whose primary vocation was law. During her lifetime, Maria Agata Szymanowska was considered an amateur pianist and composer.
