A little tip, when working with food, take the time to perfect what you are shooting.
For this particular commercial shoot, the scene was on display for a few seconds. Regardless, it was absolutely necessary to sift throug an entire box of cereal, selecting only the finest samples.
The same went for the berries, and bagels.
These were just props, and ultimate perfection would have been overkill and a costly one (although ideal).
However taking an hour or two to do this was worth its weight in the final shot.
