Thank you Wendy for your comment -- I got the spelling of "Fushia" correct in this 3D stereo image, but misspelled it on the non-stereo version. You will always be a "Gold Star" in my book. Remember in early elementary school, the teacher would place a little metalic "Gold Star" on your school paper when you did good?
Bob -- those candy-like succulents were in our little garden on the back porch. When taking macro-stereo images with one camera, the camera should move only about an inch apart between images.
My eyes are in enough trouble already without getting even more strained ... but it's good to see people are still shooting these. I think the correct way to look at them is with a viewer that puts one in front of each eye.
3D has always had its devotees, especially in the last century. Lartigue (he of the iconic 1912 racing car photo) was a particular devotee and used a twin-lens camera for that shot, though I don't know if it was actually shot in stereo.
To be honest Paul, the strain is only in the beginning. Once you have done it for a while, it becomes very easy and even 2nd nature. I'm so used to it now that I forget sometimes and converge my eyes when viewing a 2D image just out of habit. That doesn't mean I would watch a movie that way. I don't recommend prolonged freeviewing.
For those that don't like the crossview format, there are others where you don't have to cross your eyes. Each format however carries their own set of advantages and disadvantages.
If you have Red/Cyan filtered 3D glasses for instance, you could view this same image in an anaglyph format...
That's a great one Brian -- I'll look at your group. I didn't realize that you can warp the image and still have the stereo effect.
I've been taking stereo images for decades and once used an old Viewmaster to see my 3D color slides taped together -- I took it apart and created a side entery system to view them.
I once found online a simple set of glasses with little blinders that blocked out the two outside images of the three images and the viewer doesn't even realize they are even crossing their eyes. I will look it up again and see if I can find a link to that website that sells them.
Anyway -- Thanks Brian!
Thank you Paul for the info. There is a technique of training the eyes to strait viewing the images -- providing the images are in the right order, but I find it harder than cross viewing because it is difficult to ignore the rest of "reality" that conflicts with the 3D illusion.
Of course you are right, having a stereo viewer with closeup lenses that holds the stereo pair of images near the eyes are the best way to see 3D stereo images, but training the eyes to cross just enough and learning how to ignore the "outside world" also works -- and is easier.
Don't worry Ricardo -- my wife also can't cross her eyes properly and see the 3D effect. There are many people who can't -- or have not learned the technique of gently crossing their eyes so that the two images become one image with the illusion of depth inside the view.
Perhaps the real trick in cross-eye viewing is understanding the ability of ignoring all other imagery your eyes see except for the 3D image before you. Your eyes and brain may hurt a little at first because when you cross your eyes, your brain is telling you that your viewing is not normal, but with practice you can train your eyes and brain to only see and focus on the 3D image.
When you learn the cross-eye viewing technique properly, there is no pain in the eyes or brain -- and a remarkable opportunity to experience a 3D image will appear every time a cross-eye image is made available.
Ricardo - This is one of many guides found on the internet from the 3D stereo community. Assuming you see out of both eyes... it may help you to "freeview", (the term given to viewing this side-by-side 3D stereo image format). Even with the tutorial, there's no guarantee you will succeed. It's definitely worth a try however. If you've ever seen those "magic-eye pictures", the method of viewing is very much the same.
