  1. Illustrator

  2. Raster programs • Lots of programs, like MS Paint, Corel Painter, and Adobe Photoshop are RASTER based program. This means they deal mostly with pixels. • Some other programs are VECTOR based (like Adobe Illustrator) and deal with points. • With pixels, image resolution becomes important (printing, etc). • More pixels in an inch (ppi) = higher quality images (smoother, crisper, lines). Print quality is 300ppi (web quality is about 72ppi). • Ex: drawing a 5” x 5” circle at: 1ppi 4 ppi 16 ppi

  3. What’s the difference? • Raster based programs rely on pixels. • Illustrator doesn’t do this. It’s vector based, meaning it relies on points, connected to curves or lines. • The computer notes the information in each point remembers its length, curve, or angle in relation to the other points in the image. • This allows resizing, to any scale, with little to no quality loss.

  5. What tools will I learn? • This project will focus on the: • Pencil • Select/Move tool • Direct Select tool • Fill (foreground color) and Stroke (background color) • Gradient • Layers • Object Arrange Options • Opacity – Layers and Shapes

  6. Here’s the Gist • You are essentially going to be tracing the photo. Your focus is on learning how to use the tools in the program, not learning how to draw. • The higher quality your image, the easier it will be to do this. • Your photo is raster based. If you zoom in too much what will it look like? • In the end the kids really like1 realistically colored portrait, but you could really use any color combination with your students.

  7. process • Essentially you have 2 layers. • A background layer with your photo (at a low opacity). • A top layer that you’re drawing on. • You’ll draw/shade from background to foreground. • Ex: skin, skin shading, eye whites, eye iris, eye, pupil, eyelashes, hair, hair shading, etc, etc. • Oh wait, here are some process examples!

  9. WORKSPACE

  10. LAYERS = Layers are transparent workspaces, stacked one above the other. Each layer can be edited independently from the others. This is also how your shapes stack in Illustrator – the program will remember when you drew them and you can rearrange the order . Images from tutorial9.com – working with layers in PS

  11. Getting Started • I’ll demonstrate but essentially: • Log on, open Photo Booth from the doc (hit escape if you need to exit full screen mode) • Take a photo. Drag it into Illustrator (the orange AI in the doc). • With the photo selected, turn the opacity down. Lock the layer. • New layer, drag underneath the photo layer. • Draw with the pencil, filling with desired colors. Work from back to front. • Your pattern will go – draw, fill, deselect, draw, fill deselect…. • USER NAME = soguest • PASSWORD = KAEA
