Start small. Stare at the two dots below and cross your eyes until they become three dots. You’ll need to keep your head level and be patient.
The centre dot of the three that you see represents the 3D image. When the dots are stable and it’s comfortable to view, try the same thing with each of these images:
You're now freeviewing 3D! Try some more images online. Bigger images take a little practice so start small, or sit far away! - you’ll soon get used to it.
There are lots of sites that will give you more detailed info on this technique - such as this one. Some people prefer to PARALLEL freeview so give this a go if cross eyed doesn’t work for you. Or you may want to use some kind of viewer.
Most stereoscopic 3D images that you’ll come across on the internet are presented in one of three ways. The red/green/blue ‘Anaglyph’ ones you’ll know, - view them with any of those red/green glasses that you might have lying about - the glasses vary a lot in quality, try different ones out. The other format that you’ll see a lot of are Stereo Pairs. These come in two flavours, Cross Eyed or Parallel. Cross eyed pairs are best if you’re ‘freeviewing’. Parallel if you’re using equipment to view.
Now take your own 3D photos.
First you’ll need to take a couple of photos with your camera or phone. Snap the first photo then move the camera to the right about 6cm (eye distance) and take the second. This distance doesn’t need to be exact, if you’re shooting close-up the distance apart should be less (or you’ll get eye-strain), and shooting a landscape the distance would be much greater to get a stereoscopic effect.
Next stick your two photos next to each other, the first photo you took must be on the right to avoid a ‘pseudoscopic’/false stereo effect. Now you can use the technique above to view the pictures in perfect 3D! - This won’t work of course if there’s movement in your scene, in which case you’ll need a proper 3D camera - or you can join (or hold) two normal cameras together and push the shutter buttons at the same time.
This is a quick and dirty guide that should get you up and running, go

The next step from here is to download StereoPhoto Maker. With this simple and free program you can join your two images together and save them as a Stereo Pair (use ‘x’ on the keyboard to swap between cross eye and parallel views). Use StereoPhoto Maker to make an anaglyph or save as a 3D TV compatible file (.mpo). It also corrects the crop and alignment of your image to make it comfortable on your eyes (use the ‘auto alignment’ button). All the info you'll need is on their help page here.
