Exercise two: Focus with a set aperture

The purpose of this exercise was to find a seen that contained a row of things at an angele, and to then take three images with the same aperture - one focused on the nearest point, one mid-point and one focussed towards the rear.

With such a tight composition, the lack of background (and therefore context) means the the subjects take a little figuring out. They are three fire buckets captured at Bury's East Lancashire Railway Station, and each in their own right has some appeal.

Mid-point focus - 50mm, 1/100 at f/2.5, ISO 100
The focus on the middle fire bucket (image 2) has good surface detail; it has the greater surface area of the three; and the parallel lines at the top of the bucket appear to give it a certain strength that the other two don't have. However, although there is a balance brought about by the central focus it's an uncomfortable one - it doesn't lead the eye of the viewer in a particular direction.

Distant focus - 50mm, 1/100 at f/2.5, ISO 100
Near focus - 50mm, 1/100 at f/2.5, ISO 100
This criticism can't be said of the other two images. The furthest focus (image 3) leads the eye from left to right/back to front and the closest focus (image 1) takes the viewer's eye from front to back/right to left.

Both images 1 and 3 are strong, but image 1 shades it for me. Although in western cultures viewing an image from left to right is an instinctive behaviour (see Gutenburg's Diagram), image 1 leads the eye from front to back and gives a greater sense of depth to the scene.

A stronger composition may have been achieved from the left hand side of the subjects; capturing both the flow from left to right and front to back.
