Galilei wrote about Castelli's technique to the German Jesuit priest, physicist, and astronomer Christoph Scheiner. From to at least , Christoph Scheiner would keep on studying sunspots and constructing new telescopic solar-projection systems.

He called these "Heliotropii Telioscopici", later contracted to helioscope. Scheiner also made a portable camera obscura.

The image of an assistant with a devil's mask was projected through a lens into the dark room, scaring the uneducated spectators.

By Kepler used a portable camera obscura tent with a modified telescope to draw landscapes. It could be turned around to capture the surroundings in parts.

Dutch inventor Cornelis Drebbel is thought to have constructed a box-type camera obscura which corrected the inversion of the projected image.

In , he sold one to the Dutch poet, composer, and diplomat Constantijn Huygens who used it to paint and recommended it to his artist friends.

I have at home Drebbel's other instrument, which certainly makes admirable effects in painting from reflection in a dark room; it is not possible for me to reveal the beauty to you in words; all painting is dead by comparison, for here is life itself or something more elevated if one could articulate it.

The figure and the contour and the movements come together naturally therein and in a grandly pleasing fashion.

German Orientalist , mathematician, inventor, poet, and librarian Daniel Schwenter wrote in his book Deliciae Physico-Mathematicae about an instrument that a man from Pappenheim had shown him, which enabled movement of a lens to project more from a scene through the camera obscura.

It consisted of a ball as big as a fist, through which a hole AB was made with a lens attached on one side B. This ball was placed inside two-halves of part of a hollow ball that were then glued together CD , in which it could be turned around.

This device was attached to a wall of the camera obscura EF. Italian Jesuit philosopher, mathematician, and astronomer Mario Bettini wrote about making a camera obscura with twelve holes in his Apiaria universae philosophiae mathematicae When a foot soldier would stand in front of the camera, a twelve-person army of soldiers making the same movements would be projected.

He explained how the camera obscura could be used by painters to achieve perfect perspective in their work.

He also complained how charlatans abused the camera obscura to fool witless spectators and make them believe that the projections were magic or occult science.

These writings were published in a posthumous version of La Perspective Curieuse The use of the camera obscura to project special shows to entertain an audience seems to have remained very rare.

A description of what was most likely such a show in in France, was penned by the poet Jean Loret. The Parisian society were presented with upside-down images of palaces, ballet dancing and battling with swords.

The performance was silent and Loret was surprised that all the movements made no sound. Loret felt somewhat frustrated that he did not know the secret that made this spectacle possible.

There are several clues that this was a camera obscura show, rather than a very early magic lantern show, especially in the upside-down image and the energetic movements.

German Jesuit scientist Gaspar Schott heard from a traveler about a small camera obscura device he had seen in Spain, which one could carry under one arm and could be hidden under a coat.

He then constructed his own sliding box camera obscura, which could focus by sliding a wooden box part fitted inside another wooden box part.

By the magic lantern was introduced and partly replaced the camera obscura as a projection device, while the camera obscura mostly remained popular as a drawing aid.

The magic lantern can be seen as a development of the box-type camera obscura device. The 17th century Dutch Masters , such as Johannes Vermeer , were known for their magnificent attention to detail.

It has been widely speculated that they made use of the camera obscura, [55] but the extent of their use by artists at this period remains a matter of fierce contention, recently revived by the Hockney—Falco thesis.

Johann Zahn 's Oculus Artificialis Teledioptricus Sive Telescopium , published in , contains many descriptions, diagrams, illustrations and sketches of both the camera obscura and the magic lantern.

A hand-held device with a mirror-reflex mechanism was first proposed by Johann Zahn in , a design that would later be used in photographic cameras.

The scientist Robert Hooke presented a paper in to the Royal Society, in which he described a portable camera obscura. It was a cone-shaped box which fit onto the head and shoulders of its user.

From the beginning of the 18th century, craftsmen and opticians would make camera obscura devices in the shape of books, which were much appreciated by lovers of optical devices.

One chapter in the Conte Algarotti's Saggio sopra Pittura is dedicated to the use of a camera ottica "optic chamber" in painting.

By the 18th century, following developments by Robert Boyle and Robert Hooke , more easily portable models in boxes became available. These were extensively used by amateur artists while on their travels, but they were also employed by professionals, including Paul Sandby and Joshua Reynolds , whose camera disguised as a book is now in the Science Museum in London.

While the technical principles of the camera obscura have been known since antiquity, the broad use of the technical concept in producing images with a linear perspective in paintings, maps, theatre setups, and architectural, and, later, photographic images and movies started in the Western Renaissance and the scientific revolution.

While, e. In , critic Vergnaud complained about the use of camera obscura for many painting at that year's Salon exhibition in Paris: "Is the public to blame, the artists, or the jury, when history paintings, already rare, are sacrificed to genre painting, and what genre at that!

A pinhole can be seen to the left of the door. A freestanding room-sized camera obscura in the shape of a camera.

This experiment consisted of three candles in a row and seeing the effects on the wall after placing a cutout between the candles and the wall.

The image of the sun at the time of the eclipse, unless it is total, demonstrates that when its light passes through a narrow, round hole and is cast on a plane opposite to the hole it takes on the form of a moon-sickle.

The image of the sun shows this peculiarity only when the hole is very small. When the hole is enlarged, the picture changes, and the change increases with the added width.

When the aperture is very wide, the sickle-form image will disappear, and the light will appear round when the hole is round, square if the hole is square, and if the shape of the opening is irregular, the light on the wall will take on this shape, provided that the hole is wide and the plane on which it is thrown is parallel to it.

Ibn al-Haytham also analyzed the rays of sunlight and concluded that they make a conic shape where they meet at the hole, forming another conic shape reverse to the first one from the hole to the opposite wall in the dark room.

Ibn al-Haytham's writings on optics became very influential in Europe through Latin translations since circa In his book, Dream Pool Essays , the Song Dynasty Chinese scientist Shen Kuo — compared the focal point of a concave burning-mirror and the "collecting" hole of camera obscura phenomena to an oar in a rowlock to explain how the images were inverted:.

But if its image is collected shu like a belt being tightened through a small hole in a window, then the shadow moves in the direction opposite of that of the bird.

Such a mirror has a concave surface, and reflects a finger to give an upright image if the object is very near, but if the finger moves farther and farther away it reaches a point where the image disappears and after that the image appears inverted.

Thus the point where the image disappears is like the pinhole of the window. So also the oar is fixed at the rowlock somewhere at its middle part, constituting, when it is moved, a sort of 'waist' and the handle of the oar is always in the position inverse to the end which is in the water.

Shen Kuo also responded to a statement of Duan Chengshi in Miscellaneous Morsels from Youyang written in about that the inverted image of a Chinese pagoda tower beside a seashore, was inverted because it was reflected by the sea: "This is nonsense.

It is a normal principle that the image is inverted after passing through the small hole. English statesman and scholastic philosopher Robert Grosseteste c.

English philosopher and Franciscan friar Roger Bacon c. He is also credited with a manuscript that advised to study solar eclipses safely by observing the rays passing through some round hole and studying the spot of light they form on a surface.

A picture of a three-tiered camera obscura see illustration has been attributed to Bacon, [25] but the source for this attribution is not given.

English archbishop and scholar John Peckham circa — wrote about the camera obscura in his Tractatus de Perspectiva circa — and Perspectiva communis circa —79 , falsely arguing that light gradually forms the circular shape after passing through the aperture.

At the end of the 13th century, Arnaldus de Villa Nova is credited with using a camera obscura to project live performances for entertainment.

French astronomer Guillaume de Saint-Cloud suggested in his work Almanach Planetarum that the eccentricity of the sun could be determined with the camera obscura from the inverse proportion between the distances and the apparent solar diameters at apogee and perigee.

He determined the eccentricity of the sun based on his observations of the summer and winter solstices in Levi also noted how the size of the aperture determined the size of the projected image.

Italian polymath Leonardo da Vinci — , familiar with the work of Alhazen in Latin translation, [35] and after an extensive study of optics and human vision, wrote the oldest known clear description of the camera obscura in mirror writing in a notebook in , later published in the collection Codex Atlanticus translated from Latin :.

If the facade of a building, or a place, or a landscape is illuminated by the sun and a small hole is drilled in the wall of a room in a building facing this, which is not directly lighted by the sun, then all objects illuminated by the sun will send their images through this aperture and will appear, upside down, on the wall facing the hole.

You will catch these pictures on a piece of white paper, which placed vertically in the room not far from that opening, and you will see all the above-mentioned objects on this paper in their natural shapes or colors, but they will appear smaller and upside down, on account of crossing of the rays at that aperture.

If these pictures originate from a place which is illuminated by the sun, they will appear colored on the paper exactly as they are. The paper should be very thin and must be viewed from the back.

These descriptions, however, would remain unknown until Venturi deciphered and published them in Da Vinci was clearly very interested in the camera obscura: over the years he drew circa diagrams of the camera obscura in his notebooks.

He systematically experimented with various shapes and sizes of apertures and with multiple apertures 1, 2, 3, 4, 8, 16, 24, 28 and He compared the working of the eye to that of the camera obscura and seemed especially interested in its capability of demonstrating basic principles of optics: the inversion of images through the pinhole or pupil, the non-interference of images and the fact that images are "all in all and all in every part".

Italian polymath Gerolamo Cardano described using a glass disc — probably a biconvex lens — in a camera obscura in his book De subtilitate, vol.

I, Libri IV. He suggested to use it to view "what takes place in the street when the sun shines" and advised to use a very white sheet of paper as a projection screen so the colours wouldn't be dull.

Sicilian mathematician and astronomer Francesco Maurolico — answered Aristotle's problem how sunlight that shines through rectangular holes can form round spots of light or crescent-shaped spots during an eclipse in his treatise Photismi de lumine et umbra — However this wasn't published before , [40] after Johannes Kepler had published similar findings of his own.

Italian polymath Giambattista della Porta described the camera obscura, which he called "obscurum cubiculum", in the first edition of his book series Magia Naturalis.

He suggested to use a convex mirror to project the image onto paper and to use this as a drawing aid.

Della Porta compared the human eye to the camera obscura: "For the image is let into the eye through the eyeball just as here through the window".

The popularity of Della Porta's books helped spread knowledge of the camera obscura. In his work La Pratica della Perspettiva Venetian nobleman Daniele Barbaro described using a camera obscura with a biconvex lens as a drawing aid and points out that the picture is more vivid if the lens is covered as much as to leave a circumference in the middle.

In his influential and meticulously annotated Latin edition of the works of Ibn al-Haytham and Witelo Opticae thesauru German mathematician Friedrich Risner proposed a portable camera obscura drawing aid; a lightweight wooden hut with lenses in each of its four walls that would project images of the surroundings on a paper cube in the middle.

The construction could be carried on two wooden poles. Around Italian Dominican priest, mathematician, astronomer, and cosmographer Ignazio Danti designed a camera obscura gnomom and a meridian line for the Basilica of Santa Maria Novella , Florence and he later had a massive gnomon built in the San Petronio Basilica in Bologna.

The gnomon was used to study the movements of the sun during the year and helped in determining the new Gregorian calendar for which Danti took place in the commission appointed by Pope Gregorius XIII and instituted in In his book Diversarum Speculationum Mathematicarum [46] Venetian mathematician Giambattista Benedetti proposed to use a mirror in a degree angle to project the image upright.

This leaves the image reversed, but would become common practice in later camera obscura boxes. Giambattista della Porta added a "lenticular crystal" or biconvex lens to the camera obscura description in the second edition of Magia Naturalis.

He also described use of the camera obscura to project hunting scenes, banquets, battles, plays, or anything desired on white sheets.

Trees, forests, rivers, mountains "that are really so, or made by Art, of Wood, or some other matter" could be arranged on a plain in the sunshine on the other side of the camera obscura wall.

Little children and animals for instance handmade deer, wild boars, rhinos, elephants, and lions could perform in this set. They admired it very much and could hardly be convinced by Della Porta's explanations that what they had seen was really an optical trick.

The earliest use of the term "camera obscura" is found in the book Ad Vitellionem Paralipomena by German mathematician, astronomer, and astrologer Johannes Kepler.

He also realized that images are "painted" inverted and reversed on the retina of the eye and figured that this is somehow corrected by the brain.

It is believed he later used a telescope with three lenses to revert the image in the camera obscura. In , Italian mathematician Benedetto Castelli wrote to his mentor, the Italian astronomer, physicist, engineer, philosopher, and mathematician Galileo Galilei about projecting images of the sun through a telescope invented in to study the recently discovered sunspots.

Galilei wrote about Castelli's technique to the German Jesuit priest, physicist, and astronomer Christoph Scheiner.

From to at least , Christoph Scheiner would keep on studying sunspots and constructing new telescopic solar-projection systems.

He called these "Heliotropii Telioscopici", later contracted to helioscope. Scheiner also made a portable camera obscura.

The image of an assistant with a devil's mask was projected through a lens into the dark room, scaring the uneducated spectators. By Kepler used a portable camera obscura tent with a modified telescope to draw landscapes.

It could be turned around to capture the surroundings in parts. Dutch inventor Cornelis Drebbel is thought to have constructed a box-type camera obscura which corrected the inversion of the projected image.
