For some reason, I've always thought food photography was pretty cool. All of the little tricks they have to make your food look more appetizing are pretty neat. In fact, the father of someone from my PhD lab is a food photographer, and he made a special pizza slice lifter to make the pizza in photos on frozen pizza boxes look all gooey and cheesy.
This video about photographing pancakes for IHOP* is pretty funny.
* if IHOP must advertise themselves as the International HOUSE OF PANCAKES, then why do their pancakes totally suck?? They taste like wallpaper paste. Seriously. If pancakes is going to be your thing, at least make sure your pancakes are awesome. Which they are not.
