         <description><![CDATA[<p>The first time that light-sensitive materials were used in art was actually to copy a drawing, not preserve an image. In 1822, Nicéphore Niépce created the heliograph, or sun drawing, and used the process to copy engravings.In 1826 or 1827, Niépce created the “first photograph”, titled “View from the Window at Les Gras.” It is a heliographic image and the oldest surviving camera photograph.</p><p><br/></p><p><a rel="noopener noreferrer nofollow" href="https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/">https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/</a><br></p>]]></description>

         <description><![CDATA[<p>The first person believed to call to process of recording an image as “photography” was Hercules Florence. He actually worked with silver salts to produce copies of drawings in 1833 but his work wasn’t widely shared. In fact, his contribution wasn’t recognized until photography was well past its infancy in 1973.</p><p><br/></p><p><a rel="noopener noreferrer nofollow" href="https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/">https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/</a></p>]]></description>

         <title>The Daguerreotype</title>

         <description><![CDATA[<p>Considered the first form of photography, in 1837 the first Daguerreotype was made by Louis-Jacques-Mandé Daguerre, a painter who previously made sketches with the camera obscura and worked with Niépce. The images were captured on iodized silver plates and developed with mercury. While Daguerre first captured an image in 1835, the images were not permanent until he discovered that he could remove the remainder of the silver iodide using a salt solution two years later. This time the mage was fixed, did not fade and needed under 30 minutes of light exposure.</p><p><br/></p><p><a rel="noopener noreferrer nofollow" href="https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/">https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/</a></p>]]></description>

         <description><![CDATA[<p>Naming on person as the founder of photography is difficult to do because so many significant developments occurred in the 1830s. Along with Florence and Daguerre, <a rel="noopener noreferrer nofollow" href="https://rangefinderonline.com/news-features/industry-news/fox-talbot-photo-collection-shatters-auction-estimates/">Henry Fox Talbot</a> created a method for recording images by placing paper in a salt then silver nitrate solution to make the material light sensitive. He first created the technique in 1835 but it wasn’t until 1839 that he was able to make the image more permanent using a suggestion by Sir John Herschel. Talbot’s key contribution to photography is that this process is a negative, which allowed multiple prints to be made, unlike a daguerreotype.</p><p><br/></p><p><a rel="noopener noreferrer nofollow" href="https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/">https://rangefinderonline.com/news-features/10-key-moments-in-the-history-of-photography/</a></p><p><br/></p><p><br/></p>]]></description>

         <description><![CDATA[<p>In the mid-1800s, several additional photographic processes were developed that fixed an image onto different materials. During this pivotal time in photography, processes for the wet plate, calotype, tin types, glass plates, and ambrotypes were created.</p>]]></description>

         <description><![CDATA[<p>Up until the late 1870s, taking a photo required bringing the darkroom with you and developing the image on site. That changed with <a rel="noreferrer noopener" href="https://www.thoughtco.com/history-of-photography-and-the-camera-1992331">the dry plate</a>, a technique developed by several photographers including Charles Bennett.

         <description><![CDATA[<p>Prior to film, taking a photograph required considerable skill and know how. <a rel="noreferrer noopener" href="https://www.pbs.org/wgbh/americanexperience/features/eastman-history-photography/">George Eastman</a> developed rolled film in 1889. He later invented the Brownie—a pre-loaded camera that allowed amateurs to take photos, then ship the camera back to Kodak for development. Another key to making photography widely accessible was instant film, invented by Edwin Herbert land in the late 1940s.</p>]]></description>
