The edit: For this overhead ramen shot, we brought up the contrast and brightness 60 and 40 points, respectively. Additionally, we took the warmth down 20 points, and brought both saturation and sharpness up 10 points, to make details more pronounced and give it an overall more appetizing appearance.
As you can see, the original is sort of a mishmash of boring beige tones, which is no good when you're dealing with most subjects, especially food. Bringing up the brightness, plus adding contrast to dramatically differentiate between lights and darks, allows the details to pop and consequently makes it look a whole lot more appetizing. Opposite of what we did in the green-hued landscape photo, dropping the warmth accentuates the browns and beiges in the ramen bowl. Drew suggests that whenever possible you should shoot food pics under diffused natural light (e.g., light coming through a window), as it'll be much easier to get a decent shot.
