I got my first ever photography assignement and I am super nervous.

The task is going to be taking pictures on roughly 2 hour conference of an startup for social media.

I only have general idea of how can I tackle something like that and I still have over a week to prepare.

What should I watch out for and focus on? Should I use flash? I only purchased it recently, so I only know basics of using it in TTL mode.

Gear that I have- 1x speedlight flash, 1x aps camera, 1x tripod with softbox
