I've been looking at the picture and the following occured to me:
http://www.accesscomm.ca/users/wrobb/General/Linda_Gary.jpg
1) It has to involve a flat reflective surface for the image to remain the same size or
be reflected from a curved surface very close to the film (internal to the lens).
The curved face of a lens would disperse the light. As has been mentioned before,
a filter is high on the list as a culprit.
2) It is odd that the reflection was not noticed during the shoot. Moving the camera
would
have moved the reflection all about in a noticeable way. In addition, if it was
reflected
externally the flame shape should be smaller because of the distance from the
candle
to the lens back to the subject. It looks as if the candle is much closer to the
camera
than the subjects are.
3) I once had a strange reflection show up in cloe-up photography using a lens
reversing ring.
It was not seen during composition. Turned out it was due to the reflection back
from the film
onto the filter I'd left on the lens and back onto the film. I've seen this before
with photos
made with view cameras. The ground glass is not as shiny as the glass so unexpected
image
reflections are made.
