markhumpage > AS SEEN ON ITV. Feb 06 2009. It was so bright out tonight. A great op for lomg exposures and some star trail work. It has taken me all night to stack these in high quality res with PS. Original file size is just over 3 Gig!!!! Two hours worth of trails 15s exposure every 60s. Why 15s in every 60s?.....My cock up, should have been 60s in every 60s. However I have learned a useful lesson in keeping exposure time short. Noise is relativley low on 15s and light pollution is not blowing out the scene.

markhumpage > Gullfoss (Golden Falls) is a massive waterfall located in the canyon of Hvítá river in southwest Iceland. 
It is is one of the most popular tourist attractions in the country. The wide Hvítá rushes southward and 1km above the falls it turns sharply to the left and flows down into a wide curved three-step "staircase" and then abruptly plunges in two stages into a crevice 105 ft deep. The crevice is 60 ft wide, and 2.5 km in length, is at right angles to the flow of the river. 

The part frozen falls took my breath away as I first approached. Spectacular is just not grand enough to describe it. I trust the pictures help. Olympus E3, 12-60mm SWD.

markhumpage > Midnight darkness turns to day from the glow of noctilucent clouds captured above the Leics skyline on June 17/18th 2009. 

This remarkable photograph was taken at midnight and shows the rare phenomenon of 'night shining.' The shimmering clouds form at an altitude of around 55 miles above sea level and are made up of tiny ice droplets. Because they are so high up in the atmosphere the sun is able to illuminate the clouds from below the horizon.

Called 'noctilucent' clouds, which literally means 'night-shining' in Latin, they are normally spotted in polar regions during the summer months.

Noctilucent cloud formations are the highest on Earth where temperatures can plunge below -130C (-200F) and winds peak at 300mph. They appear in the mesosphere, which is between 30miles and 50miles above the Earth's surface. 

Clouds are made up of ice crystals and scientists are baffled as to how these form in an arid layer that is several million times drier than the Sahara Desert. But their prevalence in the summer months might be one clue. Upwelling winds in the summertime carry water vapor from the moist lower atmosphere toward the mesosphere.

Apparently the water droplets also need dust particles to stick to to create the ice crystals. This could explain why the phenomenon was first recorded in 1885, two years after the Krakatoa eruption, when several tonnes of carbon dioxide, ash and dust were emitted into the atmosphere.
However scientists do not know why the clouds have become more common since then rather than fading away. They have speculated that debris from space may be the answer.

markhumpage > Startrail captured on March 29th 2009 in my backyard, Leics. For the first time in a long time clear skies were forecast all night. I set my Olympus E3 camera with 8mm fisheye lens in an adjacent field on tripod. Rigged up the extension lead to provide continuous power and left it running all night. 15s exposures on continuous shoot. Nearly 1500 images stacked and placed on a single layer in Startrails.de software.

Probably one of the most impressive duration startrails I have attempted. 6 1/2 hours of slpendid earth rotation effected by the startrail.

AS SEEN ON ITV. Feb 06 2009. It was so bright out tonight. A great op for lomg exposures and some star trail work. It has taken me all night to stack these in high quality res with PS. Original file size is just over 3 Gig!!!! Two hours worth of trails 15s exposure every 60s. Why 15s in every 60s?.....My cock up, should have been 60s in every 60s. However I have learned a useful lesson in keeping exposure time short. Noise is relativley low on 15s and light pollution is not blowing out the scene.

This version has the airplane trails removed.
