The Vivid Sydney light festival has proved to be one of New South Wales' biggest and most profitable tourist attractions, with this year's edition offering more than 50 light installations scattered around Sydney's CBD from May 26 until June 17.
Vivid has officially taken over Sydney's skyline for a 13th year, after organisers promised visitors the biggest program in the popular light festival's history.

Unused tunnels under Wynyard Station are open to the public for the very first time for Vivid.
The immersive experience, called Dark Spectrum, uses lights and sounds to "mimic the human experience".
The spectacle spans over 900 metres and is broken up into eight rooms, each one representing a different aspect of life and the human experience.
"Diving beneath the surface of what is now one of the city's busiest railway lines, Dark Spectrum is a truly mesmerising and engaging experience for visitors to explore Sydney in a whole new way," Gill Minervini, Vivid Sydney festival director, said.
Opening night of the festival began with a dazzling display, which lit up 8.5 kilometres of the harbour.
The main attraction of the festival remains the 57 light projections and installations that span eight kilometres of the Vivid Sydney Light Walk, including Circular Quay, The Rocks, Barangaroo and Darling Harbour.
A festival favourite water and light show has returned to Darling Harbour, with 80-metre water shooters, flames, projection and pyrotechnics accompanied by an original soundtrack.
This year is playing host to the launch of Vivid Food, featuring 282 events across 18 venues.
The program includes pop-up restaurants to showcase the city's wide-ranging culinary culture.
Vivid's Chef Series is hosting four internationally renowned chefs in restaurants around Sydney for a unique food experience.
For between $125 and $160 a head, punters get a five to six-course meal, each with a different focus and cuisine depending on the chef.
Road closures are in place across the CBD throughout the festival period, with extra closures on weekends.
The lineup of "ideas, music and food" will fit into this year's theme of "naturally".
"The bright lights of Vivid Sydney will once again transform our city, mesmerise, delight and inspire, and I encourage both visitors and Sydneysiders alike to take part in this year's festival," Minister for Jobs and Tourism John Graham said.
