Yes, well, the couple are under the canopy, whereas the lights are in
the open, and you can't see the right-hand side of the lights.

They are also rather diminutive. In the other photos, the marker
lights are shown to be about the size of an outstretched humand
hand.

You cannot deduce that from the other photos, which anyway show them
from the back.

In the composite, even the lights behind the old couple are larger
than
their heads!

That's not true. If you enlarge that part of the photo and draw
rectangles around the lights and the heads, you'll find they are both
about 13x15 pixels. You have seen one of these lights have you?

So look at lon-hr-district03.jpg again. The single
person on the platform, whose stature is admittedly unkown, shows the
bench to be rather squat - the top of the back no higher than about
the level of the rear-end. Sitting on the bench, therefore would
hardly allow it to reach shoulder height as shown with the old
couple.

Another bit of false logic. I agree that the bench does look squat. At
a casual glance, I would say the legs are shorter than one might expect
compared to the back. So the overall height is low, but this doesn't
affect where one's shoulders are in relation to the back of the bench

As for the vending machine, hard to say for certain. The
angle of light is possibly different, but the front of the machine is
also presumably a type of clear plastic - it does at least cast a
consistent shadow, unlike the old couple who somehow have managed to
position their feet such that a shadow is cast on either side.

I think you'll find that most of the rather indistinct shadow (it's a
dull day, and they are under the canopy) comes from the bench and their
bodies, not just their legs.

It's light and shade that do the damage on composites - no matter how
hard you try, it's virtually impossible to make a fully realistic
composite that doesn't at least set of some kind of warning in the
brain. I spent a few hours on: ...

Yes, no doubt. Perhaps you could explain why all this expert knowledge
of yours led to a conclusion earlier today that "it is definitely not
Wimbledon".
