Recently, players of Kingdom Come: Deliverance II discovered that exiting photo mode while sneaking can cause Henry to suddenly speak aloud. Nearby guards can hear his lines, thereby revealing the character's location.
The incident occurred during a theft mission. The player hid near a guarded area and opened photo mode to observe the scene; upon exiting, Henry exclaimed something like "So beautiful," which alerted nearby characters. Other players also joked that while the character could patiently avoid patrols, he might loudly comment on photos at the worst possible moment.
One community explanation suggests that this mechanic may have been implemented to limit players from using a movable camera to peek around corners or scout enemies in darkness without risk. This mechanism was reportedly added via a patch, but there are currently no specific patch notes, official statements, or direct responses from Warhorse Studios, leaving its design purpose open to player speculation.
Since Henry may speak when exiting photo mode, stealth players who wish to avoid alerting guards should safely disable this mode outside the enemies' hearing range.
