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.'
他拍摄的照片为某一片星空中的几组恒星,或者一个恒星的轨迹,表示地球穿过天空的运动。
他说:“星星的轨迹图像一直让我着迷。”
“人们认为照片显示恒星在天空的运动,而实际上表示的是地球的旋转,而恒星则处于相对固定的位置。”
他还说:“对着一片充满星星的天空拍摄是没有意义的,你需要某种前景,这样可以给人以穿过图像的立体感。”
“幸运的是,住在离斯诺登尼亚这么近的地方,不缺湖泊、山峦与教堂这样可以作用作很有意思前景的东西。”
