When you corner under load, your car's weight transfers, causing wheels and tires to lean over. If you have zero camber, you have no margin when the leaning occurs, essentially causing you to lose good contact on the inside part of the tire (meaning less grip, leading to understeer). In track cars that don't have sufficient camber, there is a telltale sign: more wear on the outside half of the tire vs inside half of tire.
Having negative camber will counteract this and actually improves steering feel (since your car has a better contact patch under loading).
(Too much) negative camber also has some side effects. Obviously, the outer edge of the tire will not be doing much when you're traveling in a straight line and result in uneven tire wear. Camber also cause the car to steer into natural divots and banking of the road due to increased grip bias (the tire that is leaning will pull more).
