The Last Judgement in a stained-glass window presented the medieval peasant with two alternatives of life after death. In the top half there is eternity in Heaven with God, surrounded by the saints and the angels. In the bottom half there is everlasting torment in Hell with the damned and with such creatures as the horned "blue devil", depicted in gruesome and terrifying detail. It was the hope of Heaven and the fear of Hell that helped to drive the simple man to devote so much of what he could ill afford.

To achieve this exposure in the large image, the interior of the Church would be black. I was trying to show the size and the placement of the window i.e. it is very large and it is high up in the West end of the Nave. The Canon EF 70-300mm f/4.5-5.6 DO IS USM is just such a versatile and useful lens to have in your Camera Bag. It's there when you need it. Shame that there is no Zeiss equivalent with Autofocus and IS. Regards steve
