The festival, held in the Russian capital every year and organized by Department of Mass Media and Advertising of the City of Moscow, kicked off with a massive pyrotechnics show at Moscow State University on Friday night.
The event will run from September 23 through 27.
More than 140 Russian and international artists from 143 countries will stage over 200 light installations on well-known buildings of the capital. More than 200 video projectors will be used to display animated images on an area of 430,000 square feet.
Last year, one installation was awarded the Guinness world record for the largest projected image ever. More than 7.5 million people attended in 2015, to see the works of 129 teams from 26 countries.
Six venues throughout the city will participate in this year's festivities, including the Bolshoi Theatre, Moscow State University and VDNKh, which will be transformed into canvases for large colorful video projections.
The admission to all festival venues is free.
As part of the event, an educational program includes lectures and workshops with world-class lighting designers.
