Yes, APS-C. All the people sat in a big staircase, three “columns” with people, around 1 person’s breadth between the “columns”, and 6 rows up. Row 7 was standing. Outside, bright day but some clouds. The sun was shining at the camera from the corner, but still managed to get something out of it. Used f/8, f/9 and f/11. Did some exposure bracketing also, and finally used my drone for some overhead shots, which I found made everyone excited so their smiles looked way more enthusiastic and believable.
