Why is Henry Fox Talbot important to photography?
William Henry Fox Talbot FRS FRSE FRAS (/ˈtɔːlbət/; 11 February 1800 – 17 September 1877) was an English scientist, inventor and photography pioneer who invented the salted paper and calotype processes, precursors to photographic processes of the later 19th and 20th centuries.
What important contribution did Talbot make to photography?
In 1851 Talbot discovered a way of taking instantaneous photographs, and his “photolyphic engraving” (patented in 1852 and 1858), a method of using printable steel plates and muslin screens to achieve quality middle tones of photographs on printing plates, was the precursor to the development in the 1880s of the more …
How did Talbot stablize photogenic drawings?
Ever the tinkerer, Talbot tried fixing his prints using various techniques, including a bath of potassium iodide, which caused the photogenic drawings to fade more slowly, rather than darken over time.
Why William Henry Fox Talbot was regarded as the father of modern photography?
Talbot refined the chemicals used to sensitize the paper and created methods for fixing the image. Within 18 months of his initial experiments, he had grasped how to make these drawings permanent and, more importantly, developed the negative/positive process.
What are the advantages of a daguerreotype?
The daguerreotype had two advantages over Talbot’s paper process. First, the daguerreotype was crystal clear, whereas Talbot’s images were not sharply defined because imperfections in the paper negative reduced the quality of the final print.
Who is the father of photography?
Nicéphore Niépce was the father of photography, much more. Thomas Edison observed, “To invent, you need a good imagination and a pile of junk.” And, he should have added, time to indulge that imagination.
What are 5 advantages of digital photography?

Who invented photogenic drawing?
William Henry Fox Talbot
The British inventor of photography, William Henry Fox Talbot (1800–1877), produced his first ‘photogenic drawings’ in 1834 and in the following year made his first camera negative.
What is meant by photogenic drawing?
Talbot’s early attempts included images he made without a camera, which he called photogenic drawings, meaning drawings produced by light. The technique, known as a printed out process, brought out the image through the action of light (rather than through the use of chemicals).
What are the disadvantages of a daguerreotype?
Disadvantages. The Daguerreotype had several problems: There was no negative; each individual exposure made only one Daguerreotype – copies or enlargements were not possible except by photographing a new, inferior, Daguerreotype of the original. Some Daguerreotypes were engraved to make printing plates.
What were photographs originally called?
The first photograph So, he began experimenting with other light-sensitive substances, and in 1822, Nièpce invented a process he named “heliography” (again, using Greek words, this time meaning “sun drawing”, from helios and graphê).
What was the first camera called?
Kodak
The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1889. His first camera, which he called the “Kodak,” was first offered for sale in 1888.
How did John Talbot get his photogenic drawings?
Talbot’s photogenic drawings had been achieved by the direct action of light. When the negative was removed from the camera, the image was fully visible, but this required enormous solar energy and thus very long exposures. Talbot’s continuing researches paid off in a series of brilliant observations in September 1840.
How did Fox Talbot create a positive image?
By exposing the calotype negative produced in the camera, in contact with a further sheet of sensitised paper, a positive image was produced, and variants of Talbot’s negative-positive process were to dominate photography up to the digital age.
Which is better daguerreotype or Talbot’s paper process?
The daguerreotype had two advantages over Talbot’s paper process. First, the daguerreotype was crystal clear, whereas Talbot’s images were not sharply defined because imperfections in the paper negative reduced the quality of the final print.
What did William Talbot use to trace plants?
Talbot used this discovery to make precise tracings of botanical specimens: he set a pressed leaf or plant on a piece of sensitized paper, covered it with a sheet of glass, and set it in the sun. Wherever the light struck, the paper darkened, but wherever the plant blocked the light, it remained white.
What did John Talbot use to make pictures?
Upon returning home, Talbot resolved to find a way to produce images by “optical and chemical means alone, without the aid of any one acquainted with art or drawing.” Experimenting with drawing paper sensitized by salt and silver nitrate, he first developed what he called photogenic drawings.
Who was William Henry Talbot and what did he do?
William Henry Fox Talbot, English chemist, linguist, archaeologist, and pioneer photographer. He is best known for his development of the calotype, an early photographic process that was an improvement over the daguerreotype of the French inventor L.-J.-M. Daguerre.
