ColorTorch Pro

ColorTorch is a simple app that allows you to display colors or gradients directly in full screen. One possible application is creative portrait photography, for example, where colored artificial lights are used at night to create a very special mood, which is simply not possible during the day. For a beautiful result, two cell phones with maximum screen brightness, held very close to the model on both sides, are already sufficient. It is best to choose a lens with a long focal length for the camera, so that only the model and not the displays are visible in the picture.
The user interface has been designed to be as easy as possible so you can keep your focus on the actual photo shoot.
