Check out this video from Photoshop Principal Product Manager Bryan O’Neil Hughes as he walks through how to adjust lighting to a photo after the fact using some basic tools inside Photoshop. In this video he takes a midday photo and changes it to the appearance of a photo taken at dusk with new lighting elements within.
Adobe also showed off a demo at its MAX conference of some possible future technology that automates the process as well. Check it out below.
