Five questions about SLR cameras, please come in! ! ! (high score reward)

1, the faster the shutter speed, the less light will enter. My understanding should be correct, but I have seen many people shoot films, such as mountains, trees and other scenes, and the shutter speed is mostly 200/ 1 300/ 1 or higher, so I am very confused. -The shutter speed is fast, which can prevent blurring caused by hands. In the daytime sunshine, to ensure correct exposure, the shutter speed should be high when the aperture is not very small, so as to achieve accurate exposure. There is no need to lower the shutter speed at this time.

2. If I use external or built-in flash, I don't need to improve ISO. I think some people still improve ISO even with the help of flash. Is it necessary? What's the point? Since I have a flash, why should I improve the ISO? I can't figure this out. When do you need to improve ISO? What's more, improving ISO will destroy the image quality! -ISO can be adjusted in dark light. The safety shutter does not need to be attached, and you can take pictures. Although the photos are noisy, they are better than pasting. The flash light is hard and the shadow is big. It is a wise choice not to improve ISO as much as possible.

3. When I use aperture priority or M to slow down the shutter speed, such as 10 second, when I press the shutter, the red light on the right side of the fuselage will continue to blink until I hear a click. I want to ask you, does the camera keep exposed for 10 seconds before it hears a click? If my hands shake during this time, will the effect be very paste? Should I prepare a tripod to effectively avoid this situation? -10 second, that is, shutter open 10 second. During this period, the machine can't move, unless you want a special blur effect, you must put it on the shelf.

4. My SLR is 60D, and I want to match a tripod, which is durable and has strong load-bearing capacity to ensure the safety of the camera. I hope you can recommend it. Are there any cost-effective magnesium alloys and aluminum alloys on the market at present? I hope you can recommend it? The range of more than 200 and less than 800 is currently interested in two models. I don't know what about A 1682TB0 of Bainuo and R-2004 of Sirui. -If you don't buy a shelf, buy a lighter carbon fiber shelf. Sirui is not bad, but a little heavy. You can go and see Jebel's, carbon fiber frame and tripod head, around 1000, which is still good.

5. Besides shooting under strong light during the day, what other uses does the ND mirror have? For example, am I suitable for shooting sunsets, sunrises and sunsets on the lake? If you like it, I don't know if it is ok to just install it as a filter in the camera under normal conditions, or is ND only suitable for shooting specific scenes? -nd filter for dimming. One is that you want to blur the background with a large aperture in broad daylight, you can use it. The other is the slow door to shoot water, clouds, star orbits, etc. , also in use. It is not advisable to install all the time. If you add a pair of glasses to the lens, it is equivalent to adding a piece of glass, which will affect the image quality. So, now many people simply don't even add V-mirrors, which is the reason.

In addition: for example, in the case of insufficient outdoor light such as cloudy days, will using ND have different effects? -The light is insufficient. In order to achieve accurate exposure, it is necessary to open the aperture, improve the ISO, and slow down the shutter. How can you add the ND decompressor?
