Very good analysis Alan.  Also I was wondering from where in a  combustion 
chamber could such a picture be taken?

There's  probably no valve overlap because this is likely one of those

The reason  you don't see a white blinding light is because the light needed
to get  exposure at these high speeds will have to be much stronger than
light  caused by the explosion.  A good example of this - if you take  an
ordinary light bulb and turn it on, then stick it on an overhead  projector,
the overhead projector will project a black outline of the  bulb's element
(rather than the bulb's light) because the projector light  is much brighter
than a standard light  bulb.
