Milky Way Photography in Iriomote Island

Milky Way Photography

Milky Way Photography, my biggest challenge to date. I wouldn’t necessarily call myself an astrophotographer as such. I mean, I can’t identify by sight all of the constellations in the night skies, I know a few, not all. I don’t sit glued to a telescope scanning dark skies in the hope of catching whatever event those who stare at dark skies through telescopes are waiting for. However, I am very much attracted to the potential to photograph the majesty of the Milky Way constellation, and especially when I can do so whilst incorporating another eye catching aspect within the shot. All of the planning that had gone into a recent shot saw me traveling to the far boundaries of the Ryukyu Islands where I spent an incredible few hours under Iriomote night skies.

I had been looking for a dark sky location for quite some time and Iriomote island is perfect for that. For the best results in Milky Way photography one needs as less ambient light pollution as possible. Located some 440Km from the main island of Okinawa its landmass of 240sq/mi is comprised of mountainous peaks and ravines it serves as home to just over 2,500 people. Looking at the island it is basically a mass of Jungles, waterways, spectacular waterfalls and hidden trails. It is, to all extents and purposes a modern day Garden of Eden. I would hazard a guess as to why this island remains predominantly in a wild and natural state is due to the lack of an airport. Travelers wishing to visit the island must fly into the closest airport located on the neighboring island of Ishigaki and then take a 40min Ferry crossing to Iriomote.

With any shoot planning, specifically when it relates to Milky Way photography or any number of natural phenomenon, I use a range of smart apps with the aim to stack as much as possible the success of the shoot in my favor. Thus my quest to once again photograph the Milky Way in the night skies began. I had documented my last attempt in the form of a short film that went on to win an award at the World Time-lapse Film Festival in Santa Monica, California back in 2014. All I needed was dark skies, great weather, no ambient light pollution and a waterfall positioned so that I could shoot both it and the Milky Way in the same shot. This meant that the falls had to be large enough with enough open space around them to allow for the use of my super wide-angle Irix 15mm f2.4 lens. These requirements discounted the waterfall options on the main island of Okinawa, but highlighted the potential of Iriomote.

Beyond my Milky Way photography plans I was also very keen to shoot long exposure imagery, in daylight hours, of rivers, streams and other bodies of moving water. Iriomote, due to its topography and annual rain fall is littered with a network of rivers, streams and waterfalls, it fitted the bill perfectly. In fact there are so many waterfalls that most under 10m/33ft in height don’t have a name as there are simply too many!

With a mixture of scouring maps and researching online imagery I singled out one particular waterfall in the North West of the island. Sagara Waterfall is accessed predominantly by Kayak, not many people walk the overgrown route through the jungle, and especially not at night time. We were about to break that routine. A guide we were using for other activities suggested it would be a bit of a demanding route due to its infrequent use, in my case that’s like waving a red flag to a bull. I’d come this far into the planning, confident in my research that a one hour nocturnal trek along a seldom used and overgrown jungle pathway would be the last obstacle between me and my planned image. If there are any, the weather Gods were shining as we set about our plan to depart.

Stepping out into the night I noted from the accommodation in the main Northern settlement of Uehara that even with the ambient light pollution the night sky was just so vividly clear, game on. My start point was a 15min drive away. I never even knew if I would even be able to find the start point. My guide had said the last time he trekked this route was a number of years previous, he wasn’t sure if the route markers would even still be in place. I had to try, and eventually found the start of the route, marked with a simple red ribbon and a slight parting in the jungle vegetation, I pushed into the inky darkness.

With the night skies blotted out by the overhead canopy I stumbled, swore, farted and sweated my way through the undergrowth whilst following a succession of red ribbon route markers. Ever conscious about the potential presence of venomous ‘Habu’ Pit Vipers or seriously aggressive wild pigs that roamed these regions of low to no human intrusion, my minds raced and conjured foe from the shadows where none existed. Every now and again the sound of distant thunder created by my quarry carried on the wind, foreboding, and then I saw it…

If there was one thing I’d learned during my 12yrs of Military service, it was the Rule of 7 P’s, as in “Prior Planning and Preparation Prevent a Piss Poor Performance”. The hours spent poring over maps, checking compass settings, figuring out the trajectory of the Milky Way and at what time of the morning would allow for optimum potential to photograph the Milky Way all fell into place. It was perfect. For the next couple of hours, like a kid in a candy store I shot, explored and painted with light. I’d arrived at a time when the Milky Way was just visible at the top of the falls, I needed to wait a couple of hours in order to get it as vertical as it could whilst being truly into the dark hours of night. And then it was time…

With a head lamp at the lowest power set to its widest beam and with no other light sources from the other members of the team I initiated the above shot at 02.54am. For the first 12seconds of the planned 30second exposure I carefully ‘painted’ the surrounding vegetation with a few passes of light. Given I was shooting at ISO3200 with the lens aperture wide open at f2.4 it meant that I would record both the light of those passes as well as the stars before me in these incredible Iriomote night skies.

Given the distance between the vegetation and the Milky Way also meant that I would not create any visible light pollution in the sky areas of the shot. By using that amount of time for my shutter I also incorporated the silky water aesthetic on the waterfall, an element that creates the second, or first depending on how you look at the shot, key component of the scene. As the shutter closed I waited with bated breath the few seconds until the display LCD on my Canon EOS5DSr flooded the surrounding darkness with light. The shot was good, I was content. There remained another hour of jungle trekking to negotiate before I could contemplate the notion of sleep. It was a trek that was done in high spirits, I was a content little monster bashing through the jungle, retracing my earlier passage with happy abandon. My first real foray into Milky Way photography jad paid off in buckets. Good times.
