Conference photographic lens

Shoot the venue and take photos to improve your sensitivity, which is ISO. The higher the value, the brighter the image and the larger the aperture. The larger the aperture, the brighter the shutter speed. The lower the shutter speed, the brighter it will be, but it should not be too low, otherwise it will be blurred easily.

I don't know how dark your environment is, so it's hard to say how to match it. Sorry, hehe. So just try more before shooting, and remember what I said above should be no problem.

If the background is blurred, it is usually shot with a fixed-focus lens, and the aperture is generally between 1.8- 1.2, which is enough.

Hope to adopt!
