How to set up Canon 5D3 conference photos? 3Q, please

The high-sensitivity picture quality of 5D3 is great. In addition, the conference photos do not need to be viewed in the original size, which is more conducive to the improvement of image quality. Therefore, when shooting indoor meetings, we can boldly increase the sensitivity to shorten the shutter time and aperture size, which is convenient for taking clearer photos. Usually you can safely use ISO3200 or even 6400 indoors. Try not to use flash. Using flash in a meeting is an idiotic behavior that laymen think is very professional. Professionals try to avoid using flash, otherwise the participants' faces will become shiny and ugly, and participants with sparse hair will be miserable under the flash.

Please accept it, thank you!
