"The mythical creatures are as mysterious as light painting itself. They both emerge in the darkness, and without an exact shape or form, they are free and unrestricted. I let loose my imagination, based on the descriptions in ancient books."

Wang has been a member of the advisory board of the Light Painting World Alliance since 2015 and has met such foreign artists as Darren Pearson from the United States. Wang and Pearson have together created a light-painting photograph of a dinosaur and a dragon.

"It was clear to me that Roy's light-illustration style was progressing quickly, as both of our detailed light creations were made on the first try," Pearson writes in a recommendation for Wang's 2019 book.

"After seeing him light paint a Chinese dragon perfectly two times in a row, I could see that Roy could draw just about anything he wanted to with light."

Wang's book, Light Painting: An Artform for Everyone, stresses the photo technique does not require expensive equipment but creativity and serendipitous inspiration.
