Producing an Anaglyph ...in Photoshop or any other image editing
package that gives you access to the RGB channels for an image;
Basic steps as follows: - open the two RGB images for editing,
identify the LHS view and the RHS view. - because your typical
anaglyphic glasses are red (LH lens) and blue/green (RH lens),
the overlaid image you are going to produce will provide a LH
eye image from the red channel of the LHS view, and a RH image
from the blue/green channels of the RHS view. - go to
image>adjustment>levels and perform colour channel adjustments,
i.e. for LHS view, make green and blue output levels 0; for RHS
view, make red output level 0. - Finally, the foremost image
will also need opacity set to 50% so that you can see the
background image through the foreground. - Now nudge either
image about the canvas while you are wearing the anaglyphic
glasses. focus on a key central part of the image (this has
implications for your method or approach at photographic
composition, i.e. centrality/peripheral and
