Machinery: For this set, called River and taken near his home, Mr Long created a special machine to squirt the liquid, which could work while submerged in the water
His 'River' series was created in a river near his house, and features dramatic formations emerging from the water.
He said: 'I had the idea for River in the back of my head. I thought it would be neat to have them coming out of the water.
'I had to build an apparatus below the water surface that was water tight so that I could shoot the water into the air and capture it. It was quite a challenge.'
For another series, 'Wave/Cave' Jack built a fountain that would continuously flow in an arch over the exploding liquid forms.
'I really enjoy creating these images because I'm working in uncharted territory. It makes it that much more wonderful.
'I don't know what it will look like when I'm beginning - it's always rewarding when I see good results.
