  5. Vector images vsBitmap images • Vector images store the lines, shapes and colours of an images as mathematical formulae. When you enlarge a vector image, the formulae work out the new sizes and shapes, so there is no loss of quality. • Bitmap images are made up of millions of squares called pixels. • They have a fixed image resolution, and if you try and enlarge them you will lose picture quality.

  6. Fireworks Demonstration • Cropping • Selection Tools • Retouching • Cloning/Stamping • Text Tool
