2) If we want to make an image with 32 levels of Red, 64 levels of Green, and 32 levels of Blue, how would each pixel be represented in memory? (Extra credit: When is this particular pixel format useful?)

3) A (theoretical) 1600 dpi color printer has R, G, and B channels each with bit depth = 1. You want to print an RGB image that has bit depth = 8 for each color channel. What is the highest resolution you can choose for your printed image if you want to represent the colors 100% accurately?

4) List the steps you would go through to paint the following image.
