Matthew was by far the most knowledgeable photographer on the course: but he wasn't up himself and joined in all the exercises and helped the rest of us when we struggled - which was frequently.
Once again, the shooting data in order:
F5.6, 1/200, ISO 400, 84mm
F5.6, 1/250, ISO 400, 179mm
F5.6, 1/8, ISO 800, 163mm
The interesting stats are for that last shot in profile. Same aperture, but the shutter speed was way lower and I had to increase the ISO. He was away from the window, against the way and I was further away from him than the feature photo. All this is starting to fall into place in this poor old brain!
