Going Beyond

 

A grid can be used to help keep proportions correct when you're drawing or painting the image seen in a photograph. This strategy is commonly used by artists. A stretch can be used to manipulate the picture just like a stretch can be used to manipulate a function.

• Use an overlaid grid to stretch a picture horizontally by a factor of . This will give you a distortion similar to one you saw in the Focus section of the lesson.
• Stretch a picture vertically by a factor of . Where might you see this type of distortion?
• Stretch the picture by a factor of 2 about the line x = 3. How is this scenario different than stretching the picture about the y-axis?

Here are some hints to use when drawing from a grid:

• Select a picture that is clear with everything in focus.
• Using a finer grid will make a more accurate final product.
• Make the grid for your drawing in very light pencil and erase the grid as you draw over it.
