Photography and digital generated images
« on: January 22, 2011, 10:40:20 am »
I chose this topic to speak about photography and digital generated images. At the beginning something about history of photography:

  "Photography" is derived from the Greek words photos ("light") and graphein ("to draw") The word was first used by the scientist Sir John F.W. Herschel in 1839. It is a method of recording images by the action of light, or related radiation, on a sensitive material.

Pinhole Camera
Alhazen (Ibn Al-Haytham), a great authority on optics in the Middle Ages who lived around 1000AD, invented the first pinhole camera, (also called the Camera Obscura} and was able to explain why the images were upside down. The first casual reference to the optic laws that made pinhole cameras possible, was observed and noted by Aristotle around 330 BC, who questioned why the sun could make a circular image when it shined through a square hole.

The First Photograph
On a summer day in 1827, Joseph Nicephore Niepce made the first photographic image with a camera obscura. Prior to Niepce people just used the camera obscura for viewing or drawing purposes not for making photographs. Joseph Nicephore Niepce's heliographs or sun prints as they were called were the prototype for the modern photograph, by letting light draw the picture.

Niepce placed an engraving onto a metal plate coated in bitumen, and then exposed it to light. The shadowy areas of the engraving blocked light, but the whiter areas permitted light to react with the chemicals on the plate. When Niepce placed the metal plate in a solvent, gradually an image, until then invisible, appeared. However, Niepce's photograph required eight hours of light exposure to create and after appearing would soon fade away.

Louis Daguerre
Fellow Frenchman, Louis Daguerre was also experimenting to find a way to capture an image, but it would take him another dozen years before Daguerre was able to reduce exposure time to less than 30 minutes and keep the image from disappearing afterwards.

Thank you for such a detailed and interesting excursion into the history of photography! I was curious: how do you think modern technologies, such as digital photography and artificial intelligence, have changed the very perception of photography as an art and a means of capturing a moment? How do you think photographers, like those who work with families at theme parks, balance traditional art with these new possibilities to keep the images sincere and alive?

Digital photography allows you to take multiple pictures without film limitations, and artificial intelligence helps improve the quality of images and even suggest creative ideas for shots. In this context, portraits at Walt Disney World become not just pictures, but real living stories that convey the emotions and atmosphere of the moment. Professional photographers skillfully use these technologies to create unique shots, while maintaining naturalness and sincerity, which is especially important for family photo sessions.
