Using a slide bar for single camera macro stereoscopic photos.
2010/03/01
It was time! My desire to shoot macro photos in stereo had been increasing. I was ready to exploit the macro capabilities of the Canon SD 1200IS. I was ready for a slide bar.
While there are several web sites that sell slide bars for 3d stereo, I found it a challenge to build my own. What parts did I already have at hand? A quick search produced the results I needed. A carpenters level with T-shaped surfaces (This one from Amazon should work: Stanley 42-324 24-Inch I-Beam 180 Level) and a hole cutter for fiberglass duct. Both of these items had been previously purchased for less than $4.00 at a neighborhood garage and yard sale.
The first step was to drill and tap a hole in the bottom of the level using a 1/4 inch tap. View the results (small image or large image). This was for mounting on a tripod. Next I drilled a hole in the clamp part of the hole cutter. I needed to enlarge the slot to permit inserting a 10/24 screw for mounting the camera. See it here (small image or large image). Looking back, I should have enlarged the slot all the way across the aluminum. The hole cutter would not slide on the level. It was hitting the plastic mounts for the bubble glass. This required cutting the plastic on all three. Not an easy task!
Got the project done in about 30 minutes. Not a sparkling jewel by any means, but entirely functional. See the photo of the completed project (small image or large image)
OK, I was eager to do some close up shooting! I found a few things around the house that I felt had potential. Since my TDC film camera did not allow shots of anything close up, this was new territory for me. I used the “1/30 rule” somewhat loosely! I am posting a few of the images for your viewing and your comments.
You may choose either parallel or cross-eyed images, or select the JAVA Stereoscope Applet which will open another window with display options such as anaglyph, mirrored, or shutter glasses. It will take time to load large photos. Don’t be impatient, wait for it! It will load the photos at their full size. For ease of viewing, you will most likely need to shrink them by 50%.
If you do not have a JAVA enabled browser or you have JAVA support turned off, you will get an error message with that information.
Feedback is appreciated. Can you see 3d stereoscopic depth? Do you prefer parallel or cross-eyed views? Does the JAVA applet offer a better way to view 3d? How about the size of the images? Too large? Too small? Did the JAVA applet work for you? Was it easy to use? Leave your comments below!
