It's been over three decades since Phred Petersen began combining his passions for photography and science.
"Either I want to see how something works or I want to see whether I can actually take the photo - is it possible to capture," he says.
"I get excited by the science - the discovery. But I'm also interested in the poetry of the image."
From combustion to fuel studies, aerodynamics and supersonic flows, the senior lecturer's high-speed photography offers invaluable insights to scientists and engineers across RMIT and beyond.
Petersen's videos capture 3,000 frames per second (a standard camera takes 25), enabling processes to be observed 120 times slower than real life.
His still images require precision choreography - it can take up to three days to set up a 25-nanosecond shot.
In Liquid Lace, a droplet of glycerine and water is shown hitting a thin film of ethanol.
It's not just beautiful: what it reveals has practical application for integrated circuit manufacturing.
As such, the image perfectly captures Petersen's technically-minded creative approach.
"I don't consider myself an artist - these are just natural phenomena, I don't design them. I just know when to look."
