shutter speed

The purpose of this assignment is to consolidate understanding of Shutter Speed and how it affects motion (freezing or blurring).

SET 1

Blurring and Freezing movement

1/15s (f18 ISO 320)

1/30s (f13 ISO 320)

1/60s (f10 ISO 320)

1/250s (f5 ISO 320)

1/500s (f3.2 ISO 320)

1/1000s (f2.8 ISO 320) - The exposure changes here to slightly under. My lens only opens to f2.8, if I had a faster lens (f1.4) then the exposure would be closer to the other 5 pictures in the set.

Looking at the images above it’s clear that 1/15s creates complete blur, to the extent that the only giveaway that the wheel is actually turning, is in the blurred writing on the rim. At 1/30 and 1/60 the difference is negligible and that could be that the wheel is moving in a slightly different speed, but we now see the first signs of spokes closer to the hub. At 1/250s there is only slight blur on the edges and at 1/500s it doesn’t even look as if the wheel is moving at all.

SET 2

Panning

This takes a lot of practice. The ability to pan is a good skill to have in your tool set though.

1/400s f8 ISO 400 (54mm focal length)

Our bike rider (a nurse) looks like she’s defying the powers of gravity, sitting on an immobile motorbike.

1/30s f22 ISO 400 (24mm focal length).

We can breathe easy, she’s moving!

Back to my favorite subject (Never work with children or pets…)

Some shots from my practice run this week-end at Noanet Woodlands

1/30s (f16 ISO 320)

Waiting for my son to cross on his bicycle when the dog wanted to get in on the action too. Two projectiles moving in opposite directions, at different speeds and the shooter trying to prioritize…sheer panic!

1/30s (f16 ISO 320)

Well, that one worked.
