THE EXTRA KILOMETER (PHOTO MODE) 1.28.X MOD
This mod multiplies the maximum distance which you can move around in Photo Mode by over 7, the maximum camera’s height by over 4 and the movement speed by 3.
It also decreases the minimum ‘Field of View’ (FOV) value by a bit to allow you to zoom in closer, and sets the ‘Focusing plane position’ slider all the way to the right by default to give you a clear look of your sorroundings.
Tested on version 1.28, though I am pretty sure it should work with some older versions too.
