Digital Photography

Can you find Image evidence of the technique?

When was it first discovered and by whom?

Steven J. Sasson (b. 1950) was an electrical engineer and the inventor of the digital camera. His invention began in 1975 with a very broad assignment from his supervisor at Eastman Kodak Company, Gareth A. Lloyd: Could a camera be built using solid state electronics, solid state imagers, and an electronic sensor known as a charge coupled device (CCD) that gathers optical information.

What is special about the technique? There are many different techniques created by using a digital camera such as image editing which is where you can crop images and use various tools to make the image effective and unique. Here are many of the different options you can create using a digital camera.

How does this technique work? Can you find or describe the processes needed to make it work? Maybe illustrate how it is made. Cropping creates a new image by selecting a desired rectangular portion from the image being cropped. The unwanted part of the image is discarded. Image cropping does not reduce the resolution of the area cropped. Best results are obtained when the original image has a high resolution. A primary reason for cropping is to improve the image composition in the new image.

Can you comment how important this technique has been for the history of photography? For example was it popular and is it still used today? Cropping is an easy yet important step to consider when editing photos. Every image editing program has a crop tool that lets you trim, or eliminate, the edges of an image. Of course not every photo you take needs cropping. However, the visual impact and composition of many photos can be greatly improved when thoughtfully cropped.
