“auto” menu choice to fine-tune the pair of images so they work best together. Tis process automatically makes minor size, rotational, and geometrical adjustments to pair the two images for best viewing. You can then save the pair as a jpeg (or a jps file) which stores the left and right views as one image. Additionally, one can change the way you view the file. Te color anaglyphs here are saved separately as jpegs.
A bit more on
pop-up anaglyphs When you make a pop-up anaglyph
(phantogram), essentially what you do is take a photographic sample of reality and then put that sample on a horizontal surface so it can be viewed from the same angle. Te original article on producing phantograms involved specific instructions for Photoshop. Te way to develop these is relatively simple to describe and any number of graphics programs will allow one to do the manipulations. To do so, in the field, take left and right images as for normal stereo views. Include a
measured frame arranged horizontally around the subject. Tis will eventually be excluded from the image so keep it well away from the subject (particularly in back) and surrounding area that you eventually want to see in the final image. Te camera should be angled down onto the scene at about 45 degrees from the horizontal. Center the frame in each view (but the image of it will change slightly between left and right views). What you want to do with a graphics
program is extract the image within the measured frame on each left and right image (which will be somewhat trapezoidal) and convert it into a rectangle which has the same relative dimensions as the frame originally had. Use your graphic program’s “perspective crop” operation to cut out the part of the image within the frame: this will usually produce a rather odd-looking rectangular image of odd dimensions. Ten use your program’s “resize canvas” operation to resize this rectangular image into a rectangle of the same relative size as your frame (be sure to uncouple the resizing of horizontal and vertical sides). Tese operations
involve mathematical adjustments that ultimately may increase pixel count in some areas and decrease the count in others. You want your final image to have approximately the same number of pixels across the back (top) width as was in your image (measure the pixel count of the back width of the frame in the original image). So, consider that need when you resize the canvas (most programs allow you to adjust pixel counts).
Te final manipulation to produce
the color anaglyph phantogram (similar to the one on the cover) is to load the transformed left and right images into StereoPhotomaker, perform the auto adjustment, set the stereo view to color anaglyph and then save the image as a jpeg. I have found that it is easier to use a graphics program later to adjust the color slightly (increase saturation, adjust hue levels) for best viewing with glasses rather than doing these adjustments in StereoPhotomaker. For better color, phantograms can also be printed as left- right or right-left stereo pairs but many people have trouble viewing these.
