I used a green backdrop and a cup wrapped in green paper to elevate the speaker in the shot. I had two softboxes on either side and an on-camera speed light filling in highlights. The final is a bracketed shot and merged in Lightroom. I felt it was laking in some dynamic movement, so I added the water splashing. (just more compositing and color correction). Was It too much or needed something else?
