How to adjust the camera shutter?
Question 2: How to adjust the shutter speed of SLR cameras? Shutter priority mode or aperture priority mode can be used. Photography is nothing more than the relationship between aperture and shutter. Large aperture shutter speed is fast, and slow aperture shutter is small.
question 3: how do photographers adjust the aperture and shutter? Individuals use manual gears more.
1. First, determine which parameters are needed according to the occasion and the desired effect.
For example, if you want to blur the background, you should turn up the aperture.
To shoot scenery, you need a large depth of field, so turn down the aperture.
To shoot motion, you need a higher shutter to solidify it.
If you want to show the dynamic effect by blurring, you need a slower shutter.
when shooting and snapping by hand in dark environment, try to use a larger aperture (generally, a higher ISO is required, in order to use the shutter speed as fast as possible).
if you want to shoot a star-studded effect, use a smaller aperture.
generally, the maximum aperture is not used when using the lens of the sub-factory, but it is reduced by one step.
2. Look at the exposure indicator.
Nowadays, cameras have TTL metering. If some antique film SLR cameras don't have a exposure meter, you need an extra hand-held exposure meter to meter light.
turn the aperture or shutter dial on the camera, and observe the exposure indicator bar on the display screen or shoulder screen to determine whether the exposure parameters are appropriate. When the exposure indicator bar points to the middle position (), it indicates that the exposure is appropriate.
3. Further correct the exposure according to the color of the photometer.
Because exposure meter is based on the reflectivity of 18% medium gray, the color will also affect the accuracy of exposure meter. Light reflection is large, and the exposure measured by exposure meter is small, so the exposure should be increased. On the contrary, black should reduce exposure.
for example, I decided to use an aperture of f/2.8.
then adjust the shutter speed, and when the shutter speed is adjusted to 12s, the metering indicator bar shows the exposure just right.
However, the subject being measured occupies a relatively large proportion in the picture, and the color is relatively dark, so slow down the shutter speed to 24s (decrease by one step), which is almost the correct exposure value.
4. Further modify the exposure parameters according to the creative needs.
For example, if you take a photo with a small fresh style, you need to adjust the parameters a little too exposed.
For example, when taking a silhouette, it is sometimes necessary to deliberately darken the exposure to make the photo slightly underexposed.
in a word, it's quite complicated to say, but it's not that difficult to operate in practice.
Practice and try more, and you will soon master the basic skills of manual exposure.
question 4: how to set the aperture and shutter of SLR camera? Photography is an aesthetic art, and we need to try more about shooting methods and effects. If you have the instruction manual of this model at hand, you will have a lot of improvement if you read it several times. Learn from each other in the following points, hoping to help you
1. Sensitivity ISO:
In traditional film cameras, ISO stands for the standard of photosensitive speed. In digital cameras, the definition of ISO is the same as that of film, representing the photosensitive speed of CCD or CMOS photosensitive elements. The higher the ISO value, the stronger the photosensitive capacity of the photosensitive material. The calculation formula of ISO is S=.8/H(S sensitivity, h is exposure). From the formula, we can see that the higher the sensitivity, the less the requirement for exposure. The exposure speed of ISO 2 film is twice that of ISO 1. In other words, under the same conditions, the exposure time of ISO 2 film is half that of ISO 1 film. In a digital camera, the number of light sources and the value of picture brightness can be changed by adjusting the equivalent sensitivity. Therefore, the sensitivity has also become a value that indirectly controls the brightness of the picture.
in the traditional 135 film camera, the equivalent photosensitive value is a measure of the sensitivity of the camera negative to light, which is usually expressed by ISO number. The larger the number, the stronger the optical rotation. Commonly used methods are ISO 1, 4, 1, etc. Generally speaking, the higher the sensitivity, the coarser the particles of the negative, and the worse the magnified effect. However, digital cameras also use this ISO value to indicate the exposure adopted by the photometric system.
the traditional camera itself has no sensitivity, because the sensitivity is only a quantitative sign of the sensitivity of photosensitive materials to radiant energy under certain exposure, development and testing conditions. Anyone who has used a traditional camera knows that the most important index of film is sensitivity-a popular point is to measure how much light film needs to complete accurate exposure. We bought 1, 2 and 4 films in the camera shop, and the numbers represent the sensitivity. Sensitivity is generally expressed by ISO value. As this value increases, the sensitivity of film to light increases, so that it can be shot in different light. Films like ISO1 are most suitable for shooting outdoors in sunny days, while ISO4 films can be shot indoors or in poor light such as early morning and dusk.
However, because the camera is different from ordinary cameras, its photosensitive device uses CCD or CMOS, so there are corresponding requirements for exposure, and there is also the problem of high or low photosensitive sensitivity. This is equivalent to the fact that film has a certain sensitivity. In order to facilitate the understanding of digital camera users, digital camera manufacturers generally convert the sensitivity of CCD (or sensitivity to light) of digital cameras into the sensitivity of traditional films, so digital cameras have the saying of "considerable sensitivity".
from the perspective of measuring film sensitivity, at present, the sensitivity of digital cameras is distributed in the range of medium and high speed, the lowest is ISO5, the highest is ISO64, and most of them are around ISO1. For some digital cameras, the sensitivity is single, and the sensitivity tolerance of CCD is very small, which limits their use effect under the condition of too strong or too weak light. Other digital cameras have a certain range of sensitivity, but even within the allowed range, the shooting effect is different if the sensitivity is set high or low, so it should be placed on the best sensitivity in normal shooting. Like traditional cameras, a low ISO value is suitable for creating clear and soft pictures, while a high ISO value can compensate for the poor lighting environment.
when the light is insufficient, the use of flash is inevitable. However, in some cases, such as exhibition halls or performances, if it is not allowed or convenient to use flash, the brightness of photos can be increased by ISO value. Because of the adjustability of ISO value of digital camera, sometimes we can only reduce the use times of flash by raising ISO value and increasing exposure compensation. Increasing the ISO value can increase the brightness, but it may also increase the noise of the photo.
2. Aperture:
The English name of aperture is aperture. Aperture is a device used to control the amount of light that passes through the lens and enters the photosensitive surface in the fuselage. It is usually in the lens. The aperture values F2.8, F8, F16, etc. we usually refer to are aperture "coefficients", which are relative apertures, not the physical aperture of the aperture, and the physical hole of the aperture ... > >
question 5: how to adjust the aperture and shutter of a digital camera? If it is a digital camera with a price of around 1, yuan, don't expect to manually adjust the aperture and shutter (manual exposure is useless). The significance of adjusting the aperture is to control the depth of field. The sensor format of a small digital camera is very small, so that the actual focal length of the lens is very short, and the depth of field itself is very deep. It is futile to pursue the effect of blurring the background, and there is no need to consider adjustment. Moreover, even if a camera with a manual exposure function of about 1, yuan, the aperture of its lens is a simple aperture inserted into a medium gray filter, not a blade aperture, which can control the depth of field. A simple aperture is equal to always opening the aperture. As for adjusting the speed, the significance lies in shooting moving objects, as long as you choose the appropriate scene mode, such as sports mode, which is more worry-free than your own manual adjustment.
in a word, it has no practical significance to require a small digital camera to have manual exposure function! ! !
question 6: how to adjust the shutter speed of a SLR camera? If you want to shoot a night streamer, you need to slow down the shutter speed and take a long exposure to get that effect. SLR cameras have shutter priority mode, usually TV or S on the turntable, so you can manually select the shutter speed, or use the B door to control the shutter power according to your own desired effect. You usually need a tripod and a cable release to take this kind of photo. If the shutter speed is slow, it will paste if it shakes slightly.
question 7: how to adjust the shutter speed of canon 6D SLR camera? When the gear is set to M and Av, there will be a pile of data on the display screen, in which the parameter that shows 1/n(n is any number within 4) and has arrows on both sides is the shutter speed. Press the DISP key to switch the adjustment position to this parameter to adjust it.
question 8: how to adjust the shutter speed of Canon's 55d SLR camera? How to adjust the shutter speed, aperture and ISO under the M file? You can adjust the shutter speed by directly rotating the control dial. Hold down the Av button in the upper right corner of the LCD screen and rotate the dial at the same time to adjust the aperture size. There is an ISO button on the side of the control dial. Press it and then use the arrow keys on the back of the machine to select ISO. Press the SET button in the middle of the direction key to determine
Canon 55D SLR camera and shooting skills
Anyone who buys a new camera should read the instruction carefully, then pick up the camera and shoot for a few days, then go back and read the instruction again, then shoot for a few days, and then read the instruction again, usually at least three times ............................................................................... Because there are some contents in the manual that you can't understand without actual shooting experience, you must read it more. The manual is the best teaching material.
1 how to correctly expose the light
first, set the camera shooting mode to m, that is, full manual. (If you don't understand how to adjust to M file, just read the instruction manual, and you won't explain it in the future. If you don't understand it, just turn over the instruction manual.) Some people say that M file is not practical and troublesome to operate, and it is not easy for beginners to master, but I think M file is more suitable for beginners to learn, because M file requires manual adjustment of the circle and shutter, which makes it easier for beginners to quickly master the relationship between aperture and shutter and its influence on imaging. Anyway, I take pictures in the M file as long as it's not an emergency.
If you want to take photos in M-file, you must know how to adjust the aperture and shutter. From the LCD screen, there are three data at the top of the horizontal row, the shutter speed on the left, the light intensity in the middle and the ISO sensitivity value on the right. Normally, when the light is not very dark, we should set the ISO value to 1. If the light is very dark and we don't want to turn on the flash, we can raise it appropriately. Then how to adjust the aperture and speed is not fixed, it depends on the ambient light and the object you want to shoot. Don't worry, step by step ...
Talk about how to adjust the shutter speed, aperture and ISO under M file. You can adjust the shutter speed by directly rotating the control dial. Hold down the Av button in the upper right corner of the LCD screen and rotate the dial at the same time to adjust the aperture size. There is an ISO button on the side of the control dial. Press it and then use the arrow keys on the back of the machine to select ISO. After selecting it, press the SET button in the middle of the arrow keys to confirm.
After we know how to tune it, we will practice in actual combat. Let's find a doll or something similar or anything at home and practice it first. At this time, if you want to practice with your daughter-in-law, it is estimated that it is easy to practice your camera phobia for your daughter-in-law. Under normal circumstances, the best imaging aperture of 18-55IS lens is 8. Set the aperture to 8 first. The setting at this time is aperture 8, ISO1. After setting, put your eyes close to the viewfinder, then aim at the subject, press the shutter half-way, and you can shoot when you hear a beep.
In the viewfinder, we can see a row of numbers and scales that emit green light below. Let's talk about what this means first. The leftmost one is the speed, which is 1/125th of a second in the picture, the second one is the aperture 8, the middle scale is to test the exposure, and the right one is ISO1. Left-leaning indicates insufficient exposure. At this time, the photos taken will be black, while right-leaning indicates excessive exposure. At this time, the photos taken will shine. It is most appropriate to shoot only in the middle, but this is not absolute. This is just a reference, because different metering modes and your focus will have a certain impact on this, but let's leave it alone. At this time, if the buoy of your light measuring ruler is right in the middle, you can shoot directly. If it is on the right, you need to adjust the speed to 1/16 1/2 1/25 1/32 1/4 until the ruler is right in the middle, but be careful not to shoot too fast. If you are shooting still objects (including people and objects with still scenery), don't adjust it too fast. If it reaches 1/5 or to the right, it means that you are shooting in a sunny and very good light environment. At this time, you should stop the speed at 1/5 second and then adjust the aperture to make it smaller. Turning down the aperture means turning up the aperture value. Then zoom out until the light gauge buoy is in the middle. If your aperture is adjusted to 22 or to the right, you should continue to adjust the speed. . . By the way, who are you? > >
question 9: how to adjust the shutter speed of SLR (specific operation)? Different models of SLR of the same brand operate differently. You'd better explain what brand and model of machine you use.
For example, Nikon SLR, the entry-level D3 and D5 series, has an exposure mode dial. When the exposure mode is set in the shutter prerequisite S or manual exposure M position, the shutter speed can be adjusted, and it can be adjusted by using the instruction dial wheel. For a quasi-professional model such as D3/D7 without exposure mode dial, it is necessary to set the exposure mode to S or M first, and then use the command dial wheel to adjust the shutter speed.
another example is canon SLR, such as 5D2. when the exposure mode dial is set to shutter pre-TV or manual exposure m, the shutter speed can be adjusted by adjusting the dial wheel behind the shutter button. See page 9 of the instruction manual.
question 1: how to adjust the shutter aperture priority of SLR camera means that you set a file aperture value, and the camera will adjust it according to the current situation.
