5 questions about SLR cameras. I am always worried and hope for expert guidance! ?

The first question is that your camera lens is a kit head and has a floating aperture. It is not a constant aperture, which is very inconvenient. That is to say, if you use the 40 focal length, the aperture is 4.0, and then because of the capture, suddenly to the 18 focal length, the aperture will be 3.5. This is what I changed by myself. Then at the 55 focal length, the maximum aperture can only be 5.6. This is what I changed by myself. Even if you have an aperture of 4.0, the metering mode will still change to 5.6 at focal length 55. For example, when shooting a snow scene, if it is a piece of white snow, you focus on the white snow and then shoot directly. The photo taken is not white. It is grayish. At this time, you have to focus on gray or close to gray, that is, press the shutter button halfway, don’t release it, and then move the camera to shoot the white snow after focusing, and the white will be discharged.

The third question is, if you are not sure, it is best to use the fool mode. 80% of the time, you can try the fool mode. That is, fully automatic mode.

The fourth question, when shooting night scenes, there is no problem if the sensitivity is set to 400. Then the best shutter speed is 1/60. If it is slower, it will become blurry. As for focusing on night scenes, use a small flashlight. When focusing, turn on the flashlight and shine it on the person's face. After focusing, just turn off the flashlight. For night scenes, it is best to use a large aperture to blur the background. The large aperture I am talking about is 1.4 and 1.8. Your 3.5mm camera is simply not enough for shooting night scenes.

The fifth question is your tripod. Your sister, 30 seconds of exposure - -, it’s damned if the photo isn’t blurry.

The tripod is talking about 1/30th of a second. , not 30 seconds. Do you understand? For night scenes, a sensitivity of 800 is no problem.

The main thing is to ensure that the photos are clear. First, the shutter speed cannot be lower than 1/60. Then adjust the sensitivity. This way you can ensure it's not ambiguous.
