Classic icons like, battery level display, settings, brightness, flash, or self-timer, just to name a few. The red border was created to keep that "red ring" theme throughout the deck. Red metallic ink can be found on the back design and faces of the cards. 
 
The court cards are pretty much standard but splashed intricately with camera icons. Custom-designed jokers contain what resembles the control wheel found on most cameras. 
 
All four aces have enlarged pips with the cross-hair in the center. The Ace of Spades design was meant to look like what you would normally see on a camera display.
