The Elephant Trunk Nebula in 3 dimensions
(please see below for viewing instructions)
Please note: I found that viewing this in
3-D may cause headache, nausea, and/or eye discomfort. Please do
not view if you are prone to these problems!
Description and Viewing Instructions:
This is a 3-D version of my previous shot of the Elephant Trunk.
The left panel is the original image. The right panel is
distorted by selectively
moving certain stars or nebula regions
slightly to the right or left (to bring them into the foreground or
background, respectively) in Adobe Photoshop. In order to view,
you must stare at the center, relax your eyes, allow them to become
cross-eyed, until you see the combined image appear. It takes
some practice, but the effect is impressive. This is best viewed
with at least 1152 x 864 screen resolution.
Background and comments:
The inspiration for this comes from an article in
Sky and Telescope (December 2003), which featured the 3-D work of Akira Inaka.
Mr. Inaka's beautiful 3-D
renditions were created by using distance data from the Yale Bright
Star Catalog, which allowed him to determine the amount of shift needed
to create an accurate
illusion of distance. Unlike Mr. Inaka's work, I have used
license in creating my 3-D version, generally selecting brighter stars
and peripheral regions of the nebula for the foreground (i.e., these
shifted slightly to the right in varying degrees). I also chose
stars for the background (by shifting them to the left). Although
is not scientifically correct, it captures a quality of deep sky
objects that we all know is present (3-dimensions), but is lost in our
typical 2-D renditions. I hope that you enjoy it!
