The 48-year-old New Zealand Mountain Film Festival organiser and heli-ski guide was invited by Jean Burgun, of France, and Leo Houlding, of the United Kingdom, to be the cinematographer on the expedition which involved kite-skiing and climbing across a crevasse cut route from Union Glacier and up the unclimbed south face of the 220m-high The Spectre to Scott Glacier.
``When we first got there it stormed for four days, it was minus 35degC with a 40-knot wind, so filming in that storm was hard because of the cold.''
``I wore big down mittens when filming and a lot of the time I just turned the camera on and guessed where things were.''
Mr Sedon said every day of the expedition was hard.
``Kiwis don't talk up what they do very well. We don't dramatise it, but we just pulled it off, really.''
``It would have been so easy for one of us to break our leg or sprain an ankle ... so we all helped each other when it was needed and we were all careful and watched each other,'' he said.
In order to make the trip ``manageable in our heads'', they split the trip into four expeditions; getting to the mountain, climbing it, getting back to where they were dropped off and getting 1100km back to the base.
``So we had four mini expeditions and you'd just think about the one expedition you were doing or you would just think about the day and deal with that day, because if you started thinking about how far you had to go it almost got too much.''
Mr Sedon arrived back in Wanaka on January 28 and is already gearing up for his next trip, taking a group of six skiers from Wanaka and Dunedin ski touring through Greenland.
``Having adventures'' was what motivated him.
``Whether it is going for a walk around the lake or going for a mountain bike ride, it is kind of what keeps you alive.''
Mr Sedon will give a talk about the expedition before a screening of the film at the Mountain Film Festival in Wanaka later this year.
