In Photoshop what we've been using is a bitmap based program. It effectively and accurately captures the subtlety of color shifts. It is perfect for photography and any other mixed media with lots of subtle color shifts and layered effects. The only disadvantage is that it's not infinitely scalable.
A bitmap graphic (you may occasionally hear "raster" graphic) is basically a large grid - think of a huge checkerboard, or a screen door, or any grid with a lot of little squares. If you put a different color in each little square, you can build an image square by square. When you stand far enough away from the grid, the individual grid squares blend together and you see a complete photographic image.
Illustrator is a Vector based. In regards to this discussion, a vector graphic is one in which the shape or path of a line is defined by a bit of math. Vector graphics are basically points connected by lines of various shapes, filled with solid or gradient colors. More points and more lines can make more complex shapes. The line that defines the vector shape is referred to as the path. These images can be infinitely enlarged and actually take up less data than bitmap images.
Legg-O-ma-LOGO-HOMEWORK
On Monday, March 2, we completed our in class logo exercise for Photoshop.
For Monday the 9th. Homework please sketch five logos for an imaginary business on one piece of paper. Bring that paper in and we'll scan it. Your logo should be simple and recognizable. I would like letters, or a word and one or two graphic elements- That's it. Please no texture or fancy frills. Picture something that may be equally as noticeable on a business card as on the side of a truck. Here is another link for some help.
Follow this tutorial for some ideas for how to approach a logo workflow.
