Some cameras provide the user with
a little lever that will disengage film winding while still allowing to
wind up the shutter. Other cameras allow to do the same by pressing and
holding the rewind button while winding. Still others have electronic control
that allows to do the same. Only few decent cameras really give no way
to do it. While multiple exposure is not a must, it does allow some nice
playing.
Spheres
I simply photographed the same round
white lightbulb several times, from different distances, and using different
color filters in front of the lens, without winding the film. Today this
looks trivial, in the light of computer-based image creation tools, but
when I made this photo many years back, projecting such a slide in a darkened
room usually created a sensation!
My two brothers
But I have only one brother...
And no, he doesn't have double personality. He just posed two times for
the same picture, kissing the air, while I used the split-prism in the
viewfinder as alignment mark!
Middle ages
When I told my classmates that I wanted
to photograph them into the fire, only Eduardo (at the right) understood
and made the appropriate face. Ingrid was not very elated when I showed
her the picture and talked about witch-burning in the middle ages! Which
is not to compare her to a witch: She was one of the nicest classmates!
Behind bars
My dear grandparents never guessed
that when I asked them to kindly pose for a photo in front of a dark wall,
I had moments before shot a steel fence on the same frame!
Wine, Pisco and Whiskey don't
combine well!
The second exposure here was done
with the camera inverted and at considerably lower exposure level, giving
this phantom effect.
Leo's nightmare
Leo is the poor guy who has to keep
this helium liquefying plant running!
