The Research Camera is not just for Splicers; you can also research Big Daddies, Big Sisters, and even certain environmental elements. Continuously photographing enemies, especially new types, will grant you research bonuses. These bonuses can include damage increases against specific enemy types, new Tonics, or even unique Plasmid upgrades. For example, researching Brute Splicers might unlock a Tonic that reduces damage from their attacks. Make it a habit to pull out your Research Camera at the start of every new encounter and snap a few photos before engaging in combat. The more diverse your research, the more powerful Subject Delta becomes. research the Big Sister when you encounter her.
