OCA - TAOP - Exercise 4

Exercise 4, Shutter Speeds;

In this exercise, my aim was to "freeze" movement isomg a fast shutter speed. I also aimed to capture the effects of using a slower shutter speed with a moving subject.

For my subject, I chose cars on a fairly busy road, as they are readily available to shoot and in a built up city, they should be travelling at a fairly consistant speed of approximately 30mph in a residential area.


1/800 sec

This image was shot at 1/800 sec. This was the lowest speed that caught the whole car in focus inc. the wheels. A fairly fast speed, but it is to be expected with cars.



1/400 sec

This image was shot at 1/400 sec. The car is still easily distinguishable, as well as the driver. The edges are becoming blurred due to the movement, in particular the wheels.



1/200 sec

This image was shot at 1/200 sec. At this speed, the effects of speed are becoming more apparant with significant blurring on the edges of the taxi and the wheels. Details on the driver are becoming more difficult to distinguish and the advertising on the side of the taxi is illegible.




1/100 sec

This image was shot at 1/100 sec. Movement at this speed is becoming very apparant, individual spokes n the wheels are hard to distinguish and are starting to blend into a single blur. Other details on the car are becoming hard to distinguish such as the door handles and wing mirror.



1/60 sec

This image was shot at 1/60 sec. Details are becoming even more difficult to distinguish. The spokes on the wheels are pretty much one blur, and small details such as the door handles have all but disappeared, the driver has also started blurring into the rest of the car, and a "ghosting" type of effect is starting to form at the rear of the car.



1/50 sec

This image was shot at 1/50 sec. While there is no significant change from the previous photo shot at 1/60 sec, the ghosting / trailing effect caused by the movement of the car. The driver has all but disappeared into the blur of the car, perhaps helped by what I presume to be tinted windows.


1/40 sec

This image was shot at 1/40 sec. The ghosting effect is becoming very apparant now, especially if you look at the wheels. The driver has now completely blended in with the blur of the cars movement. Only the most significant details of the car are now distinguishable.


1/30 sec

This image was shot at a 1/30 sec. Even the most significant details of the car are becoming increasingly more difficult to distinguish. The ghosting effect is quite apparant now, especially if you look at the wheels and rear brake light.



1/20 sec

This image was shot at 1/20 sec. By this point, the vehicle is now essentially a blur, which really gives the photograph an element of speed. Especially with the ghosting effect caused by the movement blur, it makes the taxi appear to be moving significantly faster than it actually was.



1/13 sec

This image was shot at 1/13 sec. The ghosting is now very pronounced and any detail on the car is but lost. You can still distinguish easily that the subject is a car, however it now appears to be moving significantly faster than the 30mph it should be doing. The background is now becoming blurred, as at such a low shutter speed, there is now an element of camera shake caused by me.


1/6 sec

This image was shot at 1/6 sec. The car is now just a blur. All detail has been lost and it would be difficult to identify the subject as a car. The camera shake mentioned in the previous photograph notes is very pronounced, but it is the price you pay for not using a tripod at low shutter speeds, I would use a tripod in the future for similar types of shots.



1/5 sec

This image was shot at 1/5 sec. The subject is now impossiblle to distinguish, you wouldn't be sure it was a car unless otherwise told. The ghosting trial is very noticeable, if you can spot and identify the wheels and tail light. It makes it look like it is travelling at a speed far in excess of 30mph, giving a real sense of speed.
