Use a text editor such as notepad to edit the any of the .XML files file in the "config/levels/stages 1-5" directories in the game folder . In a regular stage, there are "startTime=" and "maxTime=" lines. In a photography stage, there is a "levelTime=" line. The values of those lines are in seconds and can be changed as desired. "startTime" is how much time you have to begin with. "maxTime" is how much time you would have, no matter how much bonus obtained from putting a model on the runway. "levelTime" is how much time you are allotted to take photos. Change those values as desired.
