The Camera Mod is a simple tool to allow you to take pictures in game. This functionality is different than taking a screenshot because you can then view and display those pictures within your world!
The camera requires aiming and right-clicking at your subject and as long as you have paper in your inventory then the photo should pop up instantly.
And this mod adds a custom image frame that allows you to properly hang your pictures up for anyone to see!
The images are also stored on your computer in the world save folder so you can take them out of Minecraft as well.
