How to take good photos of indoor meetings and exhibitions with a SLR (Nikon D7000)?

Because indoor lighting conditions are generally not very good, in addition to the use of external flash, the following conditions need to be guaranteed in the setting of SLR cameras:

The gear can be selected by shutter priority or M gear. Aperture priority is not recommended ... because aperture priority sometimes slows down the shutter.

Specific settings:

1, iso should be moderate. Generally speaking, in order to ensure the shutter when the light is bad, high sensitivity is needed. But this sense of height is not infinite. Too high iso will produce a lot of noise, which will affect the image quality. Therefore, when improving iso, generally do not exceed 800 ... This is the highest limit for most SLR cameras to ensure fine image quality. If it exceeds this value, it will produce noise. If the ambient light is really bad, do not exceed 1600.

2. Try to use a large aperture. Large aperture can ensure the amount of light entering, and the pressure of shutter and iso is much smaller.

3. Try to slow down the shutter, but at least ensure a safe shutter. Because people will walk back and forth during the meeting, the shutter is at least twice as big as the safety shutter.

In addition, in the choice of lens, we should choose a large aperture lens with anti-shake function. This is more conducive to film production.
