The morning sun, low in the sky, was in his eyes and he adjusted the umbrella - which made my task beyond my skill! Michaela reckoned that I take a reading for the shade; take a reading for the light. And then split the difference. Not sure how to do that: split the difference.
Top left: F9, 1/125, ISO=100, 123mm
Top right: F9, 1/125, ISO=100, 115mm
So, I tried to solve the problem by zooming in, but was way tentative.
Bottom left: F9, 1/40, ISO=100, 200mm
Bottom right: F9, 1/125, ISO=100, 116mm
So I tried to zoom in and slow the s/s to make up for the lack of light. With two effects: the facial features are more distinct, but the hand lacks all definition. I then got confused and reverted to a previous setting which I had already proved crook. Duh!
I needed to zoom in: the 200mm focal length was right.
The difference between the s/s I tried was too dramatic - try 1/80 but also open up the aperture a little by going to F8 and open up the ISO a little by going to 200.
Therefore: F8, 1/80, ISO=200, 200mm
What do you think?
