This exercise is to see the effect of following movement as it moves across the focal plane of the sensor/film.
Following the motion with the subject as near to the centre of the fame as possible, before firing the shutter (panning) I tried to stay as close as possible the same combinations of speed and aperture I did in the previous exercise.
I tried to choose moving subjects at roughly the same speed for the following images:
Shutter Speeds Panning - 1
Exposure 1/3200 sec
All movement has been frozen which almost make the car look static, no real feeling of speed or any movement.
Shutter Speeds Panning - 2
Exposure 0.001 sec (1/1600)
A combination of frozen movement and the narrow depth of field required to give the fast speed to take this shot still don't combine to give any indication of speed or movement.
Shutter Speeds Panning - 3
Exposure 0.001 sec (1/800)
Still no clear indication but on the wheels there is a just discernible lack of focus that is starting to indicate movement.
Shutter Speeds Panning - 4
Exposure 0.003 sec (1/400)
There is now clear background blur which shows that the subject has moved in relation to the background during the shot.
Shutter Speeds Panning - 5
Exposure 0.004 sec (1/250)
There is now background blur and faster moving parts such as the tyres are now showing blurring on the tread detail.
Shutter Speeds Panning - 6
Exposure 0.008 sec (1/125)
Background and wheels now showing distinct blurring but he main subject remains in focus. This clearly indicates movement at speed.
Shutter Speeds Panning - 7
Exposure 0.017 sec (1/60)
Even more feeling of speed and movement and the last point at which the main subject body is in focus... wheels are clearly spinning at a speed .
Shutter Speeds Panning - 8
Exposure 0.033 sec (1/30)
Background details is now even more blurred.Fast moving parts equally blurred and starting to lose clear definition in the furthest parts of the main subject from point of focus. Really gives a feeling of the car is travelling at a speed far in excess of the national limit even though it is slowing for a junction.
Shutter Speeds Panning - 9
Exposure 0.067 sec (1/15)
Blurring and implied feeling of speed is now increasing.
Shutter Speeds Panning - 10
Exposure 0.1 sec (1/10)
Everything is now far too fast to be able to give any clear indication of subject - just looks like an out of focus image.
Shutter Speeds Panning - 11
Exposure 0.5 seconds
Excessive blurring has now turned the background into an abstract and the excessive blurring of the moving wheel is now over emphasised.
Shutter Speeds Panning - 12
Exposure 1 second
This is now a purely abstract representation of a moving motorcycle, lack of clear definition for background and subject gives a purely abstract feeling of speed and movement, even though this is a 50cc motorcycle capable of less than 30 mph is still feels like it is travelling at close to the speed of light.
