Making 3D Images
Hi! As an old man and a child of the 80ís, I have a fascination with 3D Anaglyph photos. You know, the red/blue photos that give you a headache the more you stare at them. Well, stare at them enough and it wonít hurt anymore! Either that, or Iíve broken something in my brain . . . .
Once upon a time, I used to slave over Photoshop making 3D pictures, but a while ago I discovered a program called Stereo Photo Maker, and itís made what I spent years learning to do a piece of cake.
You can download it from here:
Stereo Photo Maker
Once youíve downloaded it, next make sure you have a pair of 3D glasses to hand. As you tinker with your photos, youíll want to have the glasses close by so you can see what your changes are actually doing.
Ready? Off we go!
In a nutshell, you take two pictures, one representing the view from your left eye, and one from your right just looking straight ahead. Before you start think about what youíre photographing, make sure thereís not too much Ďpopí; if thereís too much difference in depth perception, no matter what you do, itíll always strain your eyes.
Start off with objects/shots with mild depth and work your way up. When youíre ready to take the first picture (left), frame the object in the center, toward the right. Try not to have it too close to the edge.
Take the shot, and then move the camera to the right a few centimeters. Youíll find the object in your frame should have moved to the left, if you framed the first picture correctly, you should still have all the object visible; , if the object was too close to the left it might be out of shot now. Ideally, you want all the object in frame in both shots.
If in doubt, take multiple pictures for the right eye. With the first ĎLeftí image as a base point, move the camera toward the right a bit, take a picture, then move it a little more, take another picture and so on. Once you have practice, you probably wonít have to take multiples, but starting out itís a useful habit.
Once you have your pictures we can move to the program. Open it and youíre presented with a black screen.
Go to >File>Open Left/Right images.
Open your first Left picture, then the right picture. You should now have both pictures side by side on your screen.
Go to >Stereo>Gray Anaglyph>whatever setting best represents your glasses (red/cyan in my case)
You should get something like this.
Now that image is absolutely not ready for viewing, just looking at it through glasses will strain your eyes. Now, hereís the bit I spent years learning to do in Photoshop magically done for you.
Go to>Adjust>Auto Alignment
Wait for your computer to do itís magic and then, BOOM! Instant 3D picture. If the picture isn't what you expected, try using another one of the Right pictures and see if that works. Early on with 3D pictures, trial and error is inevitable. If no combination works, you might have your Left and Right images mixed up. Handily the program has a swap L/R button.
For something a little more advanced, try and rotate around your subject. To do this means you have to decide what your Focus point is, and rotate around that. For this example, my focus is the Scarlet Witch's left shoulder. Note as I move the camera toward the right, I keep that one part as close to the origin point as possible.
[Here it is] animated so you can see what I mean:
For this process, taking multiples is pretty much essential, because when you add the pivot to the photos the likelihood of the 3D messing up increases. Run the Photos through the Stereo Photo Maker:
Left and Right 1:
Left and Right 2
Left and Right 3:
As you can see, the pictures using Right 2 and Right 3 aren't usable. The field of depth is just too great but looking at the pictures there appears to be very little difference. The Right 1 picture only used a slight amount of movement, but the added pivot is all it needed, adding the angle difference can give you the best results but its very easy to get wrong. The Auto Alignment feature will try its best to cope, and if it canít there is a manual alignment page, but generally if Auto alignment canít cope, the picture isn't usable.
Now then, onto something Iíve only recently been playing with - color. Generally I steer clear of color in my 3D pictures as pictures with red/blue or green tend to mess up spectacularly.
Now these two pictures feature left to right movement and a little bit of pivot:
However, this time Iím using color:
From here you can fiddle with gamma, contrast, color settings to get what you want. In this case, I fiddled gamma up, contrast up, and selected Ďoptimized anaglyphí to give me this:

Mess around with the program. It really is the best way to learn fast. I hope this tutorial was somewhat informative and you have fun messing up your eyes!
I take no responsibility if you do mess up your eyes.

And here's one . . . done with the same program, but I fiddled more with the program and it came out really well.
