“Find a scene that has depth. From a fixed position, take a sequence of…shots at different focal lengths without changing your viewpoint” [Expressing Your Vision: P40]
Exif Data: Camera Sony Α6000 : ISO 200 : Aperture f 5.6
Harts Farm I : Shutter Speed 1/1600 : Focal Length 16mm
Harts Farm II : Shutter Speed 1/640 : Focal Length 33mm
Harts Farm III : Shutter Speed 1/800 : Focal Length 50mm
Not much to add to this, beyond confirming that the ‘perspective geometry’ of all three shots remains the same. The camera is not a DSLR, but a mirrorless camera, so the image that is closest to the perspective distortion of human vision is Harts Farm II at a focal length of 33mm.
From an ‘interest’ point of view, I think that Harts Farm II is the most balanced image. The reeds in the foreground are not overly distracting, the other components of the image seem somehow more proportionate to each other, and there’s not an over preponderance of sky or river. But hey, beauty is in the eye of the beholder… 😉
