Register artwork Business Art

General

To register a piece of artwork means to register it with a copyright office.  The registration of a piece of artwork can happen at any point once the artwork is finished.  The registration does not include copyright protection.  Rather, registration is a legal formality ensuring the work is on public record.  Regardless, this legal formality is essential to an artist if he hopes to license his work or show his work in any way that may put the artwork at risk of possible infringement.  There is little cost in registering pieces of artwork and a savy artist does it to basically protect the work from another person copying it.

In order to register a piece of artwork, an artist completes an application and sends it to the copyright office.  The application includes a filing fee, a deposit of copies of the artwork, and a visual arts application form.  Registration of the artwork may take a number of months.  However, the copyright leverage becomes effective starting from the date the application is received by the copyright office.  An artist may obtain copies of the application form online from the United States Copyright Office.

Renaissance Art Styles/Movements

General

The Renaissance is an art movement that emerged in Italy in the 1300s.  The term means, “rebirth” and relates to the development of interest in the past Classical feats in the arts.  The Renaissance was a time period that marked the moving away from the Middle Ages focus on religious artworks to focus on the state of the significance of mankind in society.  The creativity of the individual came into the forefront and experiences became main themes through the period’s artwork. As political stability grew in Italy, as well as the economy and thus cosmopolitanism, several changes took effect.  Education started to flourish, which encouraged the proliferation of libraries and academies.  As the economy grew, so did the arts.  Affluent persons became patrons of artists, such as the Medici family of Florence, Pope Julius II, Pope Leo X, and the Sforza family of Milan.  Interest grew in relation to the intellectual values of the Classical world.

One significant artist of this time period was Leonardo da Vinci.  He is often viewed as the archetypal figure in regard to the progressions made in literature, science and art made during the Renaissance.   Several of the famous artists of the Renaissance came from Florence; the city continued to be a significant location for the developments made during the period well into the 1500s.  The ideas of the Renaissance spread into Europe and began to affect some of the ideas in those countries.  One artist who was very much influenced by the period was Albrecht Durer from Germany.  He was a fine draftsman and became one of the many artists of the “Northern Renaissance.”  Over time, the art movement of Mannerism replaced the Renaissance; this movement had greater impact on influencing the style of the arts in the other European countries.  Important artists of the Renaissance include: Leonardo da Vinci
Sandro Botticelli, Raphael, Titian and Michelangelo Buonarroti.

Rococo Art Styles/Movements

General

An art movement begun in the 1700s in France.  During this time period, the middle-class was becoming more affluent and influential.  When Louis XIV died, the wealthy families in Paris began to take a great amount of interest in style.  The particular style that developed was called Rococo, and was mostly used for interior decorating.  The term Rococo is from the French word “rocaille” that translated means pebbles.  It is a term that relates to the shells and stones used to embellish the interior of caves.  Shells, therefore, soon became the main motif in the new style.  High class women tried to outdo each other to decorate their houses with the most intricate decorations for their homes.  The style, therefore, mainly catered to women’s tastes and preferences.

One of the artists who rose up during the period was Francois Boucher.  He was a lace designer, painter and engraver.  He became popular for his feminine landscapes and mythological paintings.  Some of his clients included the Queen of France and the influential Mme. de Pompadour, Louis XV's mistress.  It was Boucher’s style of work that came to dictate the ideal style shown in Louis XV’s court.  Gentle hues and pleasant forms characterize his light subject matter of goddesses, cupics, and shepherds.  The Rococo period is often viewed as the last chapter in the Baroque period.  Besides Boucher, other important artists of the Rococo era were William Hogarth, Giovanni Battista Tiepolo, Angelica Kauffmann, and Giovanni Antonio Canaletto.

General


(1800-1850) Romanticism represented a shift of focus away from classical forms, and placed the stress on spiritual and emotional themes. movement first started in England and Germany in the 1770’s and gradually spread around Europe and the United States in the early 1800s.  The movement originated as a reaction against Neoclassicism due to changes happening around the French Revolution and Napoleonic time period.  Rather than focus on the Neoclassicism scheme of things such as idealization, logic, balance, and harmony, Romanticism chose to stress things such as one’s emotions, imaginative ideas and freedom.  Being unstructured and not being hampered by any set rules were key ideas in the movement.  Nature and a dedication to studying how people think and feel were important.  An underlying theme throughout the movement was taking into consideration a person’s inner struggles and thoughts.  Subject matter and ideas involved the medieval era, folk cultures, occult practices, the mysterious and the exotic.  Traditional values were rejected if they hindered a person’s ability to express his individuality and emotions.  Rigorous academic training were not deemed as important as an artist’s individual creativity and personal spiritual awakening.  The ideas in the movement that involved creating intentional associations in people’s minds when viewing a painting would prove to be very influential as Symbolism, Surrealism, and Expressionism developed in the years to come. 

A few key Romanticist artists include: George Stubbs, William Blake, John Martin, Francisco Goya, Sir Thomas Lawrence, John Constable, Eugene Delacroix, Sir Edwin landseer, Caspar David Friedric, and JMW Turner.
