Remember when you are looking for photographic components (i.e. cereal, bowls, spoon, cartoon animals, or whatever) that you look for large images. It's much easier to reduce the size of an image without distortion than it is to increase it. As you have found, expanding an image makes it blurry or grainy.
Next, think about cereal names:
- ______ Loops
- ______ O's
- ______ Nuggets
- ______ Smacks
- ______ Puffs
- ______ Crunch
- Honey ________
- Sugar _________
- Crunchy ________
- Apple ________
- Spam _______

When you are finished, save a full-sized (4-panel) cereal box, but also save a copy of the cereal box cover that we can print for the wall. If you don't have a USB drive to save your work, I suggest getting one ASAP. I can loan you one of the USB drives we have for the class, but we're running low on these. Remember, you can also email PSD's to yourself as a backup. It's your responsibility to make sure you are saving your work -- especially now that we're ready to start Semester Two and you will be graded on projects [or lack thereof].
Have fun!
