How long is SLR exposure?

question 1: how to make the SLR camera exposed for a long time to produce the effect of pictures? This kind of photography, also called low-light photography, will have this effect by fixing the SLR camera and then exposing it for a long time. Your D3 is absolutely fine. You can buy a tripod, set the ISO to 1, adjust the shutter speed to 15~2 seconds, and make the aperture as small as possible. This kind of photo is very simple, and it is also one of the pleasures of shooting night scenes by SLR. < P > Question 2: How can SLR achieve long-time exposure and take photos? Shutter gives priority to setting the shutter for a long time or adjusting the aperture to the minimum in a dark place to achieve a long exposure. Don't forget to bring a tripod when you operate, or the camera will shake when you lift it. .

question 3: how to set a long exposure for Nikon D9? use a cable release with shutter lock and get on a tripod.

when the camera is set to M or S, dial the wheel to adjust the shutter for 3 seconds, then continue to turn the wheel, and door B will appear. At this time, you can decide the exposure time by yourself.

when shooting, use a small aperture, use a cable release to lock the shutter, and then unlock it after the appropriate exposure, and you can complete an exposure.

question 4: the SLR is superior. How to set exposure. The instructions are very clear. Then I'll talk about it briefly here. Generally, playing SLR is M-file, that is, full manual. Including self-adjusting aperture, shutter, sensitivity, white balance and so on. File A is the aperture priority file, also called aperture priority file, that is, the aperture is manually adjusted, and other items are automatically processed with the numerical value of your exposure meter. If you open the aperture to the maximum, that is, the maximum amount of light, the corresponding shutter speed will be increased accordingly. I suggest you use M files more, and read the instructions and some photography books.

question 5: how to make the SLR realize long-time exposure? SLR cameras can make long-time exposure by using the B door. Take Canon EOS 6D as an example: rotate the mode dial to B, press the shutter button to start exposure after focusing, and release the shutter button when the exposure is over. Please use a tripod to stabilize the camera during long exposure.

question 6: the length of exposure time of SLR. Sad people! Agree with the upstairs saying: learn some photography knowledge first.

the exposure time of a SLR digital camera is determined according to the light reflected by the lens after computer processing. After pressing the shutter, the computer determines the exposure time according to the exposure amount, and automatically closes the shutter when the time is up. So, just press it and you can lift your finger.

according to your question, it should be long exposure. Long exposure, called door B in photography, means that the shutter does not close after it is opened, and it needs to be pressed again to close the shutter, that is, the shutter power supply is turned off. Traditional cameras press the shutter and don't move. When they raise their hands, the shutter closes.

exposure means opening the shutter of the camera, allowing the light reflected by the subject to be received through the lens, and then recorded on the film, CCD or CMOS through the aperture. The length of exposure time is the length of opening the shutter. Long, can be a few minutes, a few seconds, short is a few thousandths of a second. If the subject is still, you can use the smallest aperture and take a few hours with the B-door, for example, shooting the movement of stars in the sky without any lights or the moon. Fix the camera on the tripod, adjust the focal length to infinity, and adjust the aperture to F5 (if it can't be bigger, it will make the night blue; The farthest end of a 2mm lens, the moon with a shot of fifteen requires F8 aperture). You can try a long exposure of 1 or 2 hours, and the result of the photo is the arc drawn by the stars.

during the day, it is dangerous to expose for a long time. If the sun enters the lens, it may cause the film to burn and the CCD or CMOS to be burnt. When taking full shadows during the day, you can use the minimum aperture of the camera, such as F32 or F64, and expose it for 1 to 5 minutes. You can see the light written on the photo, which is invisible to the shutter (for a short time) and invisible to the naked eye. It is caused by the long-term reflection of dust in the air. When you shoot a waterfall with a slow door, you can feel a very soft mist.

the exposure time can be controlled by yourself. However, if you want to ensure the clarity of the photo, the shutter speed when you take a photo with your hand should be as low as possible. If it is lower than the heartbeat speed, compared with 5, 4, and 3 minutes for 1 second or longer, it is necessary to mount the camera on a tripod to maintain stability.

furthermore, it is said on the internet that the camera will rust after exposure for several years. ! There are cases where plants are photographed from germination to decay. In the indoor botanical garden, the camera is fixed with a tripod. Then, the camera is set to shoot regularly, connected to an external power supply, with enough storage space, and exposed automatically at regular intervals for several months. By editing the pictures taken regularly for several months with video editing software, we can see the rapid growth process of plants.

The online exposure for several years probably means that the photos taken are developed and hung on the wall in the light for several years. Then the process of fading and aging is the "exposure" of exposure to light.

question 7: how does nikon SLR set the exposure time? You will know that it is a beginner by asking questions. I will tell you a simple method: aim at the object to be photographed with P-file, light the shutter lightly, look at the values of speed and aperture in the viewfinder, and change different objects and different light directions to see the values change in mind. Look at it by changing the aperture with A gear and the speed with S gear, and you will know their relationship over time.

question 8: how to set the dynamic feeling of the water surface, small aperture, slow shutter and tripod of the SLR camera? If the ambient light is not satisfied, you need to configure a polarizer or neutral gray. Solidification, large aperture, high shutter, tripod. All the above must be equipped with cable release

Question 9: How to operate the long exposure of Canon 6d SLR? First of all, you must have a camera stand. Otherwise, exposure for a long time, unstable hands, can not shoot a good film.

adjust to door b, and then adjust the shutter speed to more than 3 seconds (according to the traffic speed at that time, it will take longer if the traffic is slow), and adjust the ios to about 1, and the aperture is about f8.

This way, you can shoot the traffic at night and the running streams!

question 1: when does a SLR camera need to be exposed for a long time ~ how to operate the Nikon D7, which needs to be exposed for a long time when shooting night scenes, and the exposure program can be selected to door B. A tripod and cable release must be used for long exposure. Now cable release can be replaced by an infrared shutter remote controller.

to shoot the night scene of the city, set ISO4, the aperture is F8 and F5.6, and the general exposure time is 1 second to 15 seconds.

It also takes a little longer exposure time to shoot the atomized effect of running water. The aperture is between F1 and F16, and the shutter speed is 1/4 second, 1 second and 2 seconds. A tripod and a cable release are also needed.
