Sometimes, when the highest shutter speed is still unable to make the film properly exposed "to seize" the action of the object, exposure, otherwise consider. If both the poor too much, can not shoot good photos to. In fact, the clarity of high documentary photos, but often will destroy the sense of movement. From an artistic point of view, the slight blur of the image is often richer realistic nikon battery en-el5. Therefore, the photographer must be based on the required effect to determine its own clarity standards.
The shutter speed determines the movement speed of the image in the camera focal plane. The velocity of objects in general can easily use the miles / hours estimated. The inch fraction is because the calculation of the fuzzy circle as a unit, and the shutter speed based on fractions of a second unit, so for purposes of comparison, the speed of units must be converted into inches / second units. Objects move, and the images move faster than the size of the volume between the two is the same olympus battery li-40b. So the distance is doubled, the exposure can also be accordingly doubled, without a greater linear displacement.
X-lens focal length of object size ------------------ == image size
Object distance - lens focal length, such as a 6-inch focal length lens, a distance of 50 feet, shooting a 6 feet tall, is 3 per hour the speed of walking direction at right angles with the camera : 72 X 6 432 ------ == ---- = .727 when
600-6594 = image size
The ratio of the images and objects for the l 99. 52.8 inches per second speed of movement, because the object image corresponding to 0.53 inches per second speed mobile canon battery grip BG-E5. Approximate calculation, the object displacement of 50 inches per second, images per second displacement of about half inch. In other words, 1/53 seconds, the image displacement of 1/100 inches for the contact printing, the clarity of the subject's body provided by the shutter speed is acceptable. But to take into account the fact that when the whole body subject to the 3 per hour speed forward, his feet alternating movements. Feet of the mobile speed is about twice the speed of the whole body movement. Some special parts of many other moving objects. For example, a horse in the Mercedes-Benz when Horseshoe much faster than Matui of action. In the larger photo with a negative resultant loss of definition must also be taken into account.
To quickly calculate the displacement of an object's value can be obtained through the following methods approximate the velocity of the object (in miles / hour) x 20, its thanks to a number multiplied by the number of seconds on the shutter speed, canon battery bp-930 namely: the movement of objects speed (miles / hour) X-20 X-shutter speed = object displacement values
In the example cited earlier, the displacement value is calculated as follows:
3 X 20 X 1/50 = 60/50 = 1.20 inches
Control, more precise calculation of the previous calculation is 1.06 inches
A recommended shutter speed obtained using the following simple way:
Object distance (inches] ------------------------------------ velocity (yards / hour) X lens focal length (inches)
This method to calculate the above example: 6,006,001 --------- == --------- == ---- seconds
5280 X 6 31.68 thousand 53
The above calculation assumes that such a condition, with the optical axis at right angles to the canon replacement battery direction of movement of objects. If the direction of motion of an object is coming towards the camera or away from the camera away, then the displacement of the image is large only limited changes in the size available is equivalent to the original one-third of the shutter speed, direction of movement and the lens optical axis into a 45 degree angle, then the application of two-thirds of the shutter speed. And so can be launched the movement direction at the other point of view shutter speed.
The actual displacement of the image depends on its relative size, that is, depending on the lens focal length and object distance. For convenience, these two factors combined, that is a multiple of the lens focal length to estimate the distance of the object canon battery nb-3l, as shown in the table, which is calculated by 1/250 of the fuzzy circle. Degree of precision shown in the shutter speed in shutter dial is very different, and any specific shutter at any scale on the "grab" objects dynamic efficiency must go through trial and error to determine the table provides a number of test values.
Photographs, shutter speed and shoot the same distance from a fixed location on the vehicle used from a moving vehicle. When the subject is moving too fast and even can not make any existing shutter speed to "catch" their dynamics, may wish to turn the camera to shoot along the direction of motion of the object. Through practice, you can get the background blur sufficiently clear images of moving objects, this effect often gives a very real feeling.
