stereo photos
no fancy equipment, just have them snap a shot while leaning to the left
then rock to the right and snap another keeping the subject in the center of
the frame - once in front of a computer they can learn to fine rotate the
images to correct for any horizontal rotation. (if on a win PC, Irfanview
does this very quickly). Then they can resize to a about 600 pixels wide
(depending on the screen res) place the left photo on the right, right on
the left, cross their eyes and see the image in 3D. They'll also learn the
'rule' about interoccular distance is rubbish and the wider the shots are
taken, the more immersive the 3D effect will be. Wide angles are
particularly good for this.
for those who cannot cross their eyes, that might be another lesson ;)
It's quite a feeling of success to make a nice 3D image and brings greater
depth to photography. And they'll also learn another thing - often people
new to photography will make the mistake of seeing a feature of a scene and
photographing it with their minds eye view, later finding that bird or
flower is tiny in the image, they not having moved in more or chosen a
longer lens to render their subject as the main body of the image. When
they do a 3D rendering they will find this 'mistake' is less so as their
brain kicks in and again establishes a priority, enlarging the subject and
brings it to the fore - then comparing the 2D and 3D images (uncrossed eyes
V crossed) they'll understand better how the brain can get in the way of
recording an image well.
please don't beat the students if they cock it up.. I know the temptation is
sometimes strong, but it costs too much in tissues and soundproofing.
