Photography
Filming
noun, verbal noun
If you photograph a shadow, you're obviously doing some kind of photography. (In the old days photography meant using light to burn shadows onto special paper, but now it's all fancy and digital.) This isn't just still photography though; it also means filming (as in a video or movie). Basically, if it has to do with taking photos or video, 撮影 is your dude.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
お待たせして申し訳ございません。それでは、撮影を始めましょうか。
I’m sorry to have kept you waiting. Let’s start shooting now.
