Travel has inspired a teenage photographer to give the streetscapes of some of the world's biggest cities a makeover by setting them against the Tasmanian night sky.

David Lennon, a Year 12 student from Tasmania, has travelled to New York, Los Angeles, London, Singapore and Doha in Qatar.

He said he was surprised how little of the night sky was visible in the cities due to light pollution, and decided to make a video showing what the streetscape would look like with a backdrop as beautiful as Tasmania's.

"Light pollution is a mass amount of light coming into the sky that blocks the stars," he said.

"You can't see past it and it can reflect on the clouds."

Lennon took the original timelapse videos during family holidays over the past three years and replaced the sky using an editing program.

The one-and-a-half-minute video has received more than 91,000 views since it was uploaded two months ago.

"I think in Tasmania, it's pretty small, so you can see stars all the time wherever you are," he said.

"I'm a fan of going to the outdoors.

"I created the video to show what people are missing out on in the big cities.

"Mostly it's been a pretty good response.

"People are pretty fascinated by what you can see in Tasmania."

Lennon said he had been inundated with requests from journalists around the world for interviews since uploading the video, adding that he would see where his photography took him in the future.

"A few of my friends [at school] know about the video, mostly from my Instagram," he said.

"I'm just going to see what happens with it, I enjoy taking photos and making these videos."
