What do you mean by long exposure?

Question 1: What does long exposure mean? That is to say, when shooting, use a slow shutter speed (ranging from a few seconds to several hours) and set the aperture and other values accordingly to achieve a very strange shooting effect.

I took this, and the shutter speed was 30s.

Not necessarily. It depends on the rated slowest shutter speed of the camera. I shot this for 30 seconds with D90, and then I have to use B if I want to slow down. I have to see for myself. The slowest paraxial ratio of Seagull 205 still in use is 1s, followed by B. If it is a fully automatic camera, it will be a bit troublesome because you can't set the shutter speed yourself, but if there is a long exposure shooting mode,

Question 2: What do you mean by long exposure of the camera? If you shoot at night, the exposure time is longer.

That is to say, very slow shutter speed (ranging from a few seconds to several hours) is used to achieve a very strange shooting effect.

Generally, the SLR setting can reach 30S, and the B door takes more time.

The so-called B shutter, that is, B(Buble setting), also known as manual shutter, is generally engraved on the shutter adjusting button or ring, commonly known as B door. The ancient camera was controlled by an air pump, so it was called a light bulb. Modern cameras press the shutter, the shutter opens to start exposure, releases the shutter, and closes to stop exposure. In other words, the exposure time can be controlled freely.

Question 3: How can I take a long exposure? Can you describe this problem in more detail? This makes it easier for me to answer.

Long exposure requires the use of a tripod to maintain stability.

Then reduce the sensitivity, slow down the shutter speed and narrow the aperture.

You can take a few photos first, and adjust the shutter and aperture to achieve the desired effect.

You can add any questions.

Question 4: What are Gate B and Gate T? How long exposure? At present, digital cameras on the market only have B-door but not T-door, while some small portable digital cameras do not have the functions of B-door and T-door. The so-called light bulb, also known as manual shutter, means that when the shutter is pressed, the shutter opens to start exposure, and when the shutter is released, the shutter stops exposure. In other words, the exposure time of door B is determined by the length of the shutter pressing time, and it can be controlled freely without setting the exposure time. The name of door B is taken from the English word "bulb", which comes from the rubber ball squeezed out by the photographer when he opened the shutter in the old photo studio. This rubber ball shutter release device is still in use today and can still be seen on cameras in many modern photo studios. The so-called T-gate means that when the shutter button is pressed, the shutter opens, exposure begins, and the shutter continues to open until the shutter closes when the button is pressed again.

Question 5: How was the long exposure photo taken? . ? Step one: people squat down and caress.

Step 2: Adjust the sensitivity of the camera to the maximum.

Step 3: Set the camera to aperture priority or full automatic state, and then shoot at the fastest shutter speed. Of course, if the camera has continuous shooting function, don't worry.

Step 4: The photographer jumps higher, and then continuous shooting when the opponent is ready to take off. You'd better act at once when you hear the order.

Question 6: What are the advantages and disadvantages of long exposure? Main advantages: you can take photos with proper exposure in dark environment. You can also get some artistic effects.

Main Disadvantages: Long exposure will affect the picture quality. If it exceeds 1 sec, the problem of mutual translation rate should also be considered.

Question 7: What is the camera's long exposure device? The devices for long-time exposure of the camera are the B-door and T-door of the camera.

Door B: Press the shutter, the shutter opens to start exposure, release the shutter, and close the shutter to stop exposure.

T-gate: Press the shutter button to open the shutter and start exposure. Press the button again to stop exposure until the shutter is closed.

Question 8: How to expose for a long time? A300 is an entry-level SLR with a shutter speed of1/4000s-30s. In other words, for a long exposure of more than 30 seconds, you need to use the B door to manually control the radian. In order to stabilize the picture, you must also use a tripod and cable release!

As for the exposure time, the scenes vary from place to place. Fix the camera and the aperture F8, try for 2 seconds, 5 seconds, 10 seconds, 20 seconds, and you can draw a conclusion.

Question 9: What is long exposure? What are the imaging features? 5 minutes long exposure

time exposure

Judging from the failure characteristics of color film reciprocity law, it refers to a slow shutter that is slower than 1/30 seconds. Usually a few seconds or dozens of seconds of exposure.

Question 10: What does noise reduction mean in the long exposure noise reduction function? This means that thistle uses algorithms to reduce the A noise of a picture at high sensitivity, and sacrifices the image quality as the first stupid mode, mostly jpg.

Straight to the point.
