Shutter Speeds

Q1.  Why is there distortion?   

Because this photo was taken using panning, this is when this camera is moving in the same direction as the object and the people in the photo are going in the opposite direction and this causes distortion.   

Q2. & Q3. What caused this effect? 

Because this was taken on a camera phone and they have an electronic rolling shutter, which is unlike a normal SLR which has a mechanical shutter. An electronic rolling shutter is like a scanner in the way that it rolls across the image exposing it gradually.   That is why that blades are distorted in both these photos.   

  

Q4. What caused the truck to be distorted?

Similar to the first photo a panning effect would have been used, where the truck was traveling in the opposite direction to the person with the camera.

Q5.  Estimate the shutter speed used

•       Hint 1: think about typical road speed limits

•       Hint 2: examine the blur created by the car

The speed limit on this road would aprox be 60mk/h & blur has been created by the car because the camera was stationary and the car was moving. To create this they would of used a slow shutter speed, of aprox 1/10th of a second.
