The Mosquito. Definitely a bit of trickery.It could have been
done in the darkroom but was, in fact, shot in the camera.

A special effect filter was used that allowed the centre image to
be taken separately to the surrounding image on the same frame of
film, as long as the camera has a multiple exposure device.

A small aperture is also used to give a reasonably clear
separation of the two shots, and also to achieve a good depth of
field.

The map is an OS publication for Lincolnshire, showing bomber
airfields, and the mosquito picture was from a book on WW2
bombers.

Whilst not a prize winner, it does show what can be done with a
little thought, and was a lot of fun to do.
