As far as the photographers are concerned, they need to either have a window open (camera on lead.), or have the glass absolutely spot-less. So a few minutes with the Plexus, inside and out, works wonders. You could also point out that the reflections of Yellow vests on the windows will spoil their photos, so hold the lens near the glass.
You could also practice a wing down side-slip, if they want a photo of something underneath the plane... their house for example. (It might be worth demonstrating this first)
