The game calculates how much physical and magic damage the champion has dealt to enemy champions this game, and converts this to a percentage. Then, taking into account the armor and MR Camille currently has, it calculates from what type of damage Camille would take more damage, if the enemy champion deals its damage as indicated by the percentages, and gives a shield of that damage type.

So, as an example: Enemy has dealt 60% physical, 40% magic damage. Then, for every 1k damage this enemy deals, it will be 600 physical and 400 magic damage. Camille has 130 armor and 50 MR. Then, for every 1k damage this enemy deals to Camille, she would take 600/(1+1.3) = 260.9 physical damage and 400/(1+0.5) = 266.7 magic damage. Since the amount of magic damage taken will be more, Camille gains a magic damage shield against this enemy, even though it has dealt more physical damage in the game.
