Ideally, a hydrogen fuel-cell vehicle has no environmental impact. Energy is produced by combining hydrogen with oxygen pulled from the atmosphere, and the tailpipe emission is water. The hydrogen fuel could come from a number of sources (Iceland recently started pulling it out of the ground).
A fast shutter speed such as 1/400th of a second will produce a series of crisp frames that have a choppy look when played back. A slow shutter speed such as 1/30th of a second, on the other hand, will produce a series of slightly blurred frames that have a smoother look when played back.
Tips for capturing movement: 1. Slow Down Your Shutter Speed. The reason for movement blur is simply that the amount of time that the shutter of a camera is open is long enough to allow your cameraâs image sensor to âseeâ the movement of your subject.So the number one tip in capturing movement in an image is to select a longer shutter speed.uckily this isnât as hard as you might think because shutter speed and aperture settings are organized in âstopsâ. As you decrease shutter speed by a âstopâ you double the amount of time the shutter is open (eg â from 1/250 to 1/125).
