This is a semi candid ! The girl realised that the picture was
going  to be taken and is thus looking at the camera.  The shot 
was taken at the motor show and the camera, a Canon T90,  had
it`s own dedicated 300TL flash fitted to the hot shoe.

The problem with any camera mounted flash is a tendency to
deliver harsh  and  flat lighting.  There are now a number  of 
reflectors available to soften light from flash guns,  but,  in
this case,  I used a piece of translucent plastic cut from a
margarine container and attached to the flash tube with an
elastic band.

Just a bit cheaper, and it works.

Auto exposure still works as long as the diffuser doesn`t
obstruct the  flash sensing unit.  The large area of black
background  will tend to cause over exposure with some systems.
