Most of the prior shots were with the ISO on Auto, for these it is set to ISO 800 to give the dim ambient light a little more weight. This scrim shot has the speedlight aimed straight ahead and the scrim several inches away, at the end of the zoom lens. So there is some light spill below the scrim, but the scrim still catches the bulk of the light. Even with the scrim cutting the light intensity the speedlight is strong enough to need the TTL EV pulled back to -0.5
