Learning the basics of Editing

• Most cameras come with a photo editor in the package. So do most scanners. Computers can also have photo editors, notably Microsoft Paint or Adobe Photoshop
• Vector graphics define lines and shapes as actual objects
• When you describe an image like this, each bit is mapped to a specific location on the grid, which is to say, the image consists of a bunch of mapped bits, and the image is called bitmapped
• drawing program
• An example of a drawing program used by professionals is Adobe Illustrator
• paint programs.
• a straight line, for example, and a vector graphics program knows where it starts and where it stops.
•  a circle, and the program knows where the center is and how large the radius is
• So just as the word draw in a program name tells you that you’re dealing with a vector graphics program, the word paint tells you that you’re dealing with a bitmapped program.
• Adobe Illustrator, The alternative to describing images as a collection of lines and shapes is to think about the image as a grid of bits (in the sense of being the smallest part of the image, not a computer bit). You then define the position and color of each bit
• The most common reason for rotating an image is that you shot it in vertical format
• 1. One of the most common is that there is some distracting element 2. want to close in on the subject of the photo. 3. photo is a cluttered mess
