Digital Photography Editing

Raster images are stored in a computer in the form of a grid of picture elements, or pixels, which contain the image's color and brightness information. The image can be enhanced in many ways by utilizing image editors to change these pixels. The pixels can be modified as a group, or individually, by the complex algorithms within the image editors.

Bitmap graphics editors, such as Adobe's Photoshop, are often used to alter photographs and other raster graphics. However, vector graphics software, such as Adobe Illustrator or Inkscape, can be used to create and change vector images, which are stored as descriptions of lines, Bézier splines, and text instead of pixels.

It is simpler to rasterize a vector image than to vectorize a raster image. How to vectorize a raster image is at the center of much research in the area of computer vision. Many people prefer vector images because they are easy to modify, and contain descriptions of the shapes in them for easier rearrangement. They are also scalable, being rasterizable at any resolution. To rasterize a vector image is simply to render it, while scaling a raster image up entails guessing at data that isn't there. Even the scaling down of a raster image involves conjecture unless the scaling factor is an integer.

With all of the advancements in digital technology, taking and improving photographs is quick and simple. The photo-mat is a thing of the past with the image of our pictures being available in seconds on our digital camera's screen.

Even with all of the advancements in cameras, pictures are still not always free of mistakes. Now we can correct our photographs both old and new through digital imaging software that can be done easily by anyone wishing to enhance and improve their photos.
