Intrepid Dan Arkle scaled the Peak District on his own without ropes, capturing his exact route by using long exposure camera techniques to catch his every move.

When you spend hour traversing Britain's most
picturesque peaks, you always want some kind of visual souvenir to
commemorate your efforts.
And while most climbers opt for a standard panoramic image, bright spark Dan Arkle marked his journey with these spectacular light trails thanks to a head torch and some camera wizardry.
The intrepid 34-year-old scaled the Peak District on his own without ropes, capturing his exact route by using long exposure camera techniques to catch his every move.
Dan, from Sheffield, had to endure freezing cold temperatures as well as navigate course and treacherous rock only using minimal light available.
The stunning light trails show how traversed rugged terrain before scaling fearsome peaks and descending back to ground level again on his treacherous climbs.

Dan's stunning pictures also capture dramatic star trails thanks to his photographic technique (Caters)The long exposure element of his photos also provides spectacular backdrops in the form of star trails across the night sky.
Dan prides himself on his ability to capture star trails within his amazing photographs.
He said: "The star trails in the sky are formed when the stars appear to move in the sky due to the earth spinning on its axis (just as the sun does).
"As the North Star (Polaris) is above the North Pole, it appears stationary and the other stars seem to move round it.
"Any exposure of longer than a few seconds will result in some star movement being captured.
While climbing a landmark known as Higgar Tor he had to climb the rock by painfully jamming his hands into cracks.
He said: "I got to the top of the first climb the rock was covered with ice.
"As I was climbing solo and ropeless, this gave me a few scary moments until I found a way round, the climbs are around 60 foot high.
"Climbing was strenuous and a little painful, but keeping my hands in the cracks also means that I felt secure.
"There was no danger of slipping off unexpectedly, but I knew I would have to get to the top before I got too tired or my hands got too cold."
Light Painting Photos of Rock Climbers Wearing Glow Sticks
What do you get when you combine rock climbers, glow sticks, and
long-exposure photographs? Answer: some pretty neat light painting
pictures.
St. Paul, Minnesota-based photographer and rock climbing enthusiast Matt Holland
was able to experiment with rock-climbing light-painting photography
recently when he went climbing at night with a group of friends in
Jasper, Arkansas.
All the climbers were decked out with red headlamps and bright
chemical glow sticks. The glow sticks were of the bracelet/necklace
variety, so they were worn on arms, legs, helmets, harnesses, and shoes.
The headlamps helped illuminate the rock face while the glow sticks
added colorful light trails showing the climbs.
Holland was using a Canon 7D and a 15-85mm EF-S lens, “wide open at
f/3.5 and zoomed out”. To capture the exposures, he used a cheapo Canon
cable intervalometer as his remote shutter release, and used bulb mode
to start exposures when the climbs began and stop them when the climbers
reached the top.
Exposure times for full climb photos ranged from around three minutes to around five minutes.
Here are a few of the resulting light painting photographs from the climbs:
Holland tells us he was inspired to send in these photographs after seeing our post earlier this week on photographers who dropped glow sticks into waterfalls as a light painting experiment. You can find more of Holland’s photographs from the light-painting climbing session here.

Time and Motion
It soon became apparent that motion analysis could be applied
usefully to the demands of the workplace where it could be used to
determine the most efficient use of workers’ time and energy. This
became known as ‘Time and Motion’ study.
One of the main tools of time and motion studies were
‘chronocyclegraphs’ - still pictures taken with long exposures in which
motion paths are traced by small electric lamps fastened to the
workers’ hands
