I am typing from my iPhone, which I want to use to shoot a short film.
I’ve recently downloaded FiLMiC Pro and want to custom set the white balance to give my images a bluish hue. I thought of installing an app on my second device (LG L4 II tri-SIM, E470) that would enable me to use its screen to display a solid colour (a plain orange, in this scenario). I would then point the iPhone’s camera to the screen and lock the white balance.
Anyone got an app you can suggest me to install? Perhaps a second option would be a camera app that can manually set white balance, or a color grading app?
