Analysis of Historical Photography
The art of photography is a glorious one. Utilizing photography, you can keep hold of the greatest scenes from your life. Then you can look at them whenever you wish, to enjoy and treasure them. Moreover, you will be able to capture the stunning scenes of nature which are sources of freshness and beauty.
However, have you ever thought about how the concept of photography developed? As a matter of fact, photography as an art has been around for hundreds of years. Individuals have always been ardent admirers of beauty and they have always wanted to capture beauty of any kind. However, the technology available a few centuries ago was not as developed as it is nowadays, in the modern age.
This article will look at the past, to when photography arrived, and how its popularity has grown since then.
“Photography” as a phrase and concept was introduced by Sir Jon Herscel around the early 1830s, when the world came to know this brand-new concept. Photography is actually derived from two words: ‘photo’ and ‘graphein’ which means recording pictures with the help of radiation or light.
Photography is nowadays only about recording images with the assistance of light. The French painter and chemist Daguerre was first to produce a photograph. Traces of photographs have been discovered as early as the mid-to-late 1820s, which would suggest that such a technology did exist in some form before 1839 (i.e. which is when Daguerre produced the first recorded photograph).
Photography became very prominent in 1847 when photographs of the Mexican-American war were shown in the Americas, reaching the public. The public started to see the future of photography, and they came to know that this new technology was about to revolutionize their lives.
The first colored photographs – which were very basic – were published in 1861. This then generated a real interest in photography all around the world, due to it being such a new and amazing idea. Having said that, this method mainly involved tinting the photographs, which understandably doesn’t produce the same high quality result as we have with color photos today.
Photography equipment kept on improving – and the photos created also kept on becoming more impressive and remarkable (for the time) – until 1991 when the first digital camera appeared on the international scene.
This digital camera technology produced a very large interest, and then many people produced many colorful photos of their friends, family, and other scenes. Many more companies then started to produce a larger variety of cameras – ever maximizing their quality – which naturally resulted in the wonderfully high quality photographs that we have nowadays.
In the modern world, fashion and electronic media are all about photography. Due to all this, photographs today – especially their usage in advertising – has made people’s lives a lot more colorful and visually stunning!
