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.
4. Use the Shutter Speed Priority Mode. Motion blur is all about shutter speed. To bring out the motion in the backdrop and keep the subject in focus, start with a shutter speed of 1/200th of a second and slow down gradually depending on the results and the speed of the subject.This will help you to determine the optimum shutter speed for motion blur in those conditions.o bring out the motion in the backdrop and keep the subject in focus, start with a shutter speed of 1/200th of a second and slow down gradually depending on the results and the speed of the subject.
