Digital photography is quickly becoming pervasive in our society and as a result of that photo editing software is also drawing a lot of attention. A photo editing software allows you to improve your digital images. For example, you can crop them, remove red-eye, change colors or contrast, and even add and delete elements. Installing photo editing software is like having a darkroom with the lights on and without the chemicals.
Once a photograph is in digital form, you can store it on your system and then edit or manipulate it with a photo editing software such as Photoshop. The things you can do to a digital image are almost endless. In some cases you improve an image by eliminating or reducing its flaws. In other cases, you adjust an image for other purposes, perhaps to make it smaller for e-mailing or posting on a Web site. Finally, you might take an image to a new place, making it something it never was.
Here are some of the things you can achieve with such products. With Photo Editing Software, you can crop the photograph to emphasize the key part. Reduce the size of the photograph to make it smaller for posting on the Web or e-mailing. Use filters to sharpen it or even make it look like a watercolor or oil painting. Stitch together multiple frames to create 360 degree panoramas. Merge two images to create a 3D stereo effect, or an animated image for display on the Web. Change brightness and contrast to improve the image. You can also cut and paste parts of one image into another to create a photo montage, or convert the photograph to another format (like from JPEG to GIF).
Every photo editing software works with digital images that are made out of tiny little squares known as pixels. Every photo presented on the computer monitor, consits of thousands of pixels that make up the whole image. The software applies changes to those pixels. It first reads the values stored in the digital photograph's file to specify the brightness and color of each pixel. Controlling, or addressing a grid of individual pixels in this way is called bit mapping and digital images are called bit-maps. The quality of a digital image, whether printed or displayed on a screen, depends in part on the number of pixels used to create the image (sometimes referred to as resolution). More pixels add detail to an image, sharpen edges, and increase resolution. The size of the image is measured in pixels, either by its dimension given in pixels or by the number of pixels it contains.
