Ruins of Elgin Cathedral

This is the ruins of 13th century Elgin Cathedral in northern Scotland. I revisited the image and put together a 3-photo composite -- the ruins, the sky, and the flowers. I selected the flowers, which were taken about 20 miles away, using the quick selection tool in Photoshop. Notice all of the images were taken in diffused light. This is essential to make composites believable. The storm clouds replaced the original white (and boring) sky, and I used the Sky Replacement command for that. The cathedral was abandoned in 1560 after the Scottish Reformation in which the UK broke from the Papacy and Catholic mass was outlawed. My settings were 1/400, f/22, and 1250 ISO. I took the shot of the cathedral with a 70mm focal length, and even though the lens aperture was small, the reason this image has complete depth of field is because each of the three elements were sharp.
