Across the top, you have to know the relation between the aperture and the deep definition of photography. The next family picture ideas of you will care about it's speed. As mentioned in the first part, the amount of light in the film depends on open short display duration, but can be combined with changing the aperture to obtain the same image brightness with the speed. On the rate of less than 1s are denoted by a conventional figure. For example 250 means 1/250s, 30 is 1/30s ... The speed is greater than 1s, denoted figure comes with 2 example 〞 "is 2s, 8" is 8s.When capturing moving subjects is time you will pay attention to the shooting speed. To catch the subject standing you will have to shoot at a rapid pace. In contrast to the blurry image as motion (motion blur) will take a slower pace. See the illustration below to see more clearly.
Taking the car in motion, but you clearly see that the speed the more slowly the theme as unknown. When taking pictures with no tripod to not be "shaking hands" will typically be taken with speeds from 1/30s even at 1/60s or older. Taken at a slower pace, requires you to use your legs.
When shooting in low light professional photography is not capable of shooting at a slow pace, you will have to resort to glass filter ND (Neutral Density). This filters will help you reduce light intensity on lens. In contrast when taking night lighting conditions are not enough, you have to have the tripod to shoot with slower shooting speed.
I will return to this portion of the ND filters in more detail after this post.
When you want to show the movement of the subject, you will use the techniques go (paning). That is when the shooting will be lia "cling". Then the theme will be, the wallpaper will be overshadowed.
Sometimes capturing landscapes, there needs to be a certain motion as the rain falls, water drains .... then you will also use a slower speed. Compare the two images below you will see the effect of taking a slow pace to create moving images of the stream.
