The changing seasons are something that makes Britain special: the lengthening days, the turning leaves, the first touch of frost.
These little signs are things that we naturally tune into – things that make our landscape unique.
In making The Great British Year, the team and I had to bring these moments to life on camera and, thankfully, today’s technology was a tool that helped like never before!
Much of the series relied on time-lapse filming - a technique that allows us to bring events in nature, that take many minutes, weeks or hours, to life - sometimes revealing things that would never have been obvious when viewed in normal time.
Slime moulds look little more than blobs of yellow goo, yet they are fascinating and unique creatures that munch their way across the forest floor at about 1mm per second, clearing away bacteria from the leaf-litter.
Tim is no stranger to slime moulds, and using a carefully-constructed set where he could get in close with macro lenses and proper lighting, managed – over several weeks – to understand the slime mould’s behaviour and capture its remarkable life story through the lens.
Through time-lapse, a yellow blob comes to life as a moving, feeding character!
We also needed to capture events in the natural world that happen rapidly, and unpredictably... in places it would be too hard to reactively scramble a camera team.
For that, we cast the net out wide, to the nation’s fleet of amateur time-lapse photographers.
Technology today, means that almost anyone with a good-quality digital SLR camera can go out and shoot time-lapse – you can even do it on your mobile phone.
OK, the quality we needed had to stand up to broadcast level, but using Twitter and photography forums we began to tap into a network of time-lapse enthusiasts whose work was excellent, and who were ready and waiting in locations all across the UK.
One of these locations was the northernmost tip of Scotland – one of the only parts of Britain that witnesses the aurora.
Though clear to human eyes, the aurora is too faint for most cameras to film, but time-lapse, where each frame may be exposed for several seconds, allows enough light into the camera to capture the effect.
But predicting something so enigmatic is tricky, and it would have been very difficult for a camera crew to guarantee filming when conditions were right.
Enter Barry Stewart, a builder from Wick. Barry got in touch with the team via an online forum for amateur time-lapsers.
A keen photographer, Barry works as a joiner by day and by night, his hobby is filming with the time-lapse technique.
Barry had been photographing the night sky for a while, but one evening he happened to be out when an aurora was ‘playing’ overhead.
Aurora activity is related to sun activity, which works on a roughly 11-year cycle. It goes through phases with low activity (meaning auroras are relatively uncommon), and then phases when spectacular events occur.
Over the following months, Barry – along with fellow Wick time-lapser Maciej Winiarczyk – went out many times in order to document the best aurora.
Some shots were made from the sea shore, others from the local golf course – but all involved braving long hours in the cold Scottish night!
By working with people on the ground, suddenly a sequence of the Northern Lights which we didn’t dare hope to achieve, became possible.
Barry, and our other time-lapse contributors added the magic ingredient to The Great British Year – capturing ephemeral, yet magical moments in our seasonal landscape that it would be impossible to plan for or predict.
It’s a wonderful demonstration of how passionate people are about documenting Britain’s landscape – it may be our backyard, but the seasonal events on our doorstep can be an inspiration to us all.
Barry Stewart features in the Making The Great British Year section at the end of episode three.
