WAITING four days for the perfect lighting to do justice to the bloody and moving story behind a former Great War battlefield, Michael St Maur Sheil was nothing if not patient.
The Oxford-educated photo journalist embarked almost a decade ago on the ambitious project aiming to showcase the scars, regeneration and legacy of 66 of the most poignant scenes of war – and says it changed his life.
A onetime history novice, Mr Sheil originally intended his "easing into retirement" project to be published as a book but the collection, along with the photographer's passion for the past, grew beyond his wildest expectations.
"Eight years ago I knew nothing about military history, but I am now in a party of people doing a five-day battlefield tour," he says.
A tour of the western front's trenches and the graves of the fallen is however, just the tip of the iceberg when it comes to Mr Sheil's involvement and expertise in the subject.
In eight years, the former Time magazine and Newsweek photo journalist has progressed from what was somewhat of a working schoolboy's knowledge of the 1914-1918 conflict to becoming a qualified battlefield guide and elected member of the British Commission for Military History.
Speaking to the Post from French trenches ahead of the Nottingham leg of his touring photo exhibition, he said he was overwhelmed by how many people had seen his work so far.
The exhibition was launched in April in Paris, where 1.6 million people saw it. The English version was unveiled by the Duke of Kent at St James's Park, off Horse Guards' Parade, London.
Mr Sheil says: "That was something really special, to exhibit in St James' Park, which doesn't to my knowledge normally have exhibitions, that was extraordinary."
Nottingham has the honour of being the first city outside London to host the touring street exhibition. It runs here from tomorrow until November 11 and includes nine Nottingham-based panels showing the city council and Trent to Trenches logos next to information about the county at war.
And while the 66 large pictures will be the same as those displayed in London, the information on the panels will be adapted to reflect Nottingham's history and involvement in the Great War.
The Nottingham subject areas covered are:
The first shot of the First World War, fired by Nottinghamshire boys of Royal Horse Artillery's E Battery
The Boots factory during the war and the development of pharmaceuticals as a consequence of the conflict
The Wipers Times, which was started by Notts soldiers
Zeppelin raids on the city
Albert Ball, the Nottingham-born flying ace
The Chilwell shell factory explosion
Franz Ferdinand's visit to Welbeck Abbey and the hunting accident that nearly killed him a couple of months before his assassination
HMS Nottingham, which was sunk by torpedoes
John Player & Sons' cigarettes and their importance to the troops on the front line.
The exhibition also includes a huge walk-on map of the world showing the battlefield locations and an education unit, both of which will be displayed in Nottingham's Old Market Square.
Once the trail leaves Nottingham it will tour various cities across the country for the next five years.
Mr Sheil says: "I'm not sure how it is going to work in Nottingham as it will be the first time that the photos have been distributed around a city.
"At the moment they are all together and it is organised with a theme in mind, so it will be interesting to see.
"It's a wonderful thought that people may be walking through the city doing their shopping or going to work and they will stumble upon these pictures almost by accident."
"It mirrors quite well how, during the war, young men may have just been walking along the streets when someone grabbed them by the collar and shipped them off to France. It grabs you quite unexpectedly."
He adds: "I wanted the pictures to tell a story which, as a photo journalist, I understand.
"Most landscape photographers will pick a place of natural beauty, whereas my methods were dictated by history and that has been the challenge."
Mr Sheil, who is of Irish heritage, chose to shoot the pictures in colour.
He said: "All the First World War photographs are in black and white, so it is a striking contrast which really demonstrates quite well how time has passed."
Mr Sheil has visited more than 60 countries over the course of his prestigious career – which has included work on child trafficking in West Africa and the bomb squad in Northern Ireland during the 1970s.
The following quote by First World War veteran P J Campbell, which written at the end of the war, inspired the conception of the Fields of Battle project.
"They were everywhere... they would not be lonely,
"There were too many of them.
"I saw that bare country before me...
"...but the country would come back to life...
"They would lie still and at peace below the singing larks, beside the serenely flowing rivers.
"They could not feel lonely, they would have one another.
"And they would have us also ...we belonged to them, and they would be a part of us for ever."
He then approached the late, well-respected, military historian Brigadier Edward Richard Holmes, known as Professor Richard Holmes, eight years ago to help him with his project.
He says: "Richard and I decided it would need to be made into an exhibition but we didn't want it to be in a museum or gallery because we wanted it to be accessible to all and not everyone goes to museums and galleries. I think what we should be doing is learning from history, we shouldn't just be getting maudlin about it, walking around cemeteries and looking at memorials."
The experience has been an emotional adventure and he cites one of his most moving moments when he was allowed to take a 99-year-old football (above) out of a museum to replace it on the very same soil it was kicked on back in September 1915.
He says: "I travelled a lot shooting the exhibition, and some shots are more emotional than others.
"You need a lot of patience – and an understanding wife."
