His photos show clusters of stars in a starfield, or a star trail, which shows the movement of the earth through the sky.
He said: 'I've always been fascinated by star trail images.
'People think it shows the stars moving through the sky, whereas in reality what they display is the rotation of the earth, with the stars staying relatively stationary.'
He added: 'There's no point getting pictures of a blank piece of sky full of stars, you need something in the foreground to lead people through the image.
'Fortunately, living so near to Snowdonia means there's no shortage of lakes, mountains and churches to use as foreground interest.'
他拍攝的照片為某一片星空中的幾組恒星,或者一個恒星的軌跡,表示地球穿過天空的運動。
他說:“星星的軌跡圖像一直讓我著迷。”
“人們認為照片顯示恒星在天空的運動,而實際上表示的是地球的旋轉,而恒星則處于相對固定的位置。”
他還說:“對著一片充滿星星的天空拍攝是沒有意義的,你需要某種前景,這樣可以給人以穿過圖像的立體感。”
“幸運的是,住在離斯諾登尼亞這么近的地方,不缺湖泊、山巒與教堂這樣可以作用作很有意思前景的東西。”
