Scanned Textures ©1998 Alison King Objective: Students will learn that scanned textures can have more than one interpretation by selectively scanning, enlarging, shrinking and adjusting textures for use in their own digital paintings. Motivation: Have you ever seen a photograph of something very close-up, and then couldn't believe what it was when you saw the same entire object from far away? Dialogue: We know now that digital paint can help us at creating all kinds of artificial effects, such as perfect, crisp lines and stunning, precise gradients. What are some ways that we can use close-ups on the scanner help our digital paintings appear more natural or organic? What qualities of color and texture are missing when we paint with the regular paint tools in HyperStudio? When would you need to use a texture that you normally couldn't get using the paint tools we have available? Once you have a texture in your paint environment, do you have to keep that texture the same? When might one texture look like another with the help of your painting tools? Could one texture be "mistaken" for another without any manipulation? [ scan in a texture that somebody has brought in ] Demonstration Dialogue: When we look at this texture as it scanned in, what does it remind you of? Shall we scan the entire sample, so that the texture is small, or just part of the texture very close up, so that the texture is enlarged? What happens to this texture when we scan it both ways? What happens when we take this scan and change the set of color values? What happens when we adjust the brightness and contrast? Visualization: What kinds of things in your own paintings could use a little texture like this? Will you have to scan in that literal texture (i.e. grass) or can you find a suitable substitute for it that might be easier to scan? Transition: What kinds of textures do we have available in this room that might make an interesting texture to paint with or manipulate?
