During this session we got the chance to experiment with the effect known as "3D" where we changed 2D images and made them appear as if to bounce off the screen.
This technique is used in pictures, animations, movies and more recently games and is a great effect to create.
This as an example was simple to make and the tutorial I based if off is easy to follow as well. (Tutorial: http://www.erodov.com/forums/making-3d-images-photoshop/15189-page2.html)
The whole blue and red levels effect clearly shown is not understandable by our average sight thus requires a pair of 3D glasses, (which you can either purchase or make yourself). The red and the blue filters on these glasses allow us to properly see the layers of the image which were before very blurry and confusing. Now with this new envisioned sight can we discover the amazing 3D effect that has been created.
Basic process: Duplicate the layer >> Change the top layer levels to Red: 255 Blue: 0 Green: 0 and switch the layer style to 'Screen' >> Change the bottom layer levels to Red: 0 Blue: 255 Green: 255 >> Move the top layer along a few pixels to see the effect take place.
The more the top layer is shuffled to whatever direction you chose, the more the effect is concentrated.
Both these images can be seen in the 3D effect with a pair of 3D glasses. 3D glasses work by covering our eyes over with blue and red cellophane, one to right and one to left (respectively); this is because our colour perception is different in each.

At first glance, looking at these two pictures confuses our eyes, making it appear somewhat fuzzy. Without getting into too much detail, having the red and blue screen over our sight helps focus the image thus creating the 3D effect. As we turn our head, the image appears to become possible to look around as if it were real life almost.
The “trick”:
It is actually possible to get this effect without the need for special colours and glasses to see it, although this method is more tricking the mind than the eyes.
If you look at these two photos they may appear the same but there is a significant different; it may not be easily visible but the images are different.
The way this trick works is you have to cross your eyes while focusing on both images (looking into the centre) until a 3rd image appears between them. If you focus correctly this new picture is a mix up of both meaning if you turn your head slightly it will appear to change from one image to the next. Although this technique is not 100% effect for everyone, it is a neat trick :)
Explanation: "Most people see out of two eyes. This is a basic fact of humanity, but it's what makes possible the illusion of depth that 3-D movies create. The eyes in a human are spaced about two inches apart, meaning that each eye gives the brain a slightly different perspective on the same object. The brain then uses this variance to quickly determine an object's distance."
3D in games (emulators mostly)
3D has now proven to be a small succession with games as well as movies or simple animations. Although it has not become such a hit with large production companies, it is somehow possible in emulators by installing a program the “iZ3D driver” and adjusting the screen settings on the game itself.
In some discussions by enthusiastic gamers, they have discovered that it is a succession for N64 emulators and have been able to play games such as Zelda in 3D.
It is a mystery as to why larger software companies have not caught onto this earlier but guesses are it might be harder to convert some of our newer graphic games into 3D than the general public are making out.
Sky TV - 3D
Sky has recently released a special feature called 'Sky 3D' in which they've introduced the cinema popular '3D' to films from homes. This is definitely a huge step forward into the entertainment of 3D yet it will never completely popular due to the fact some people's eye sight just can't focus on the effect.
