I have uploaded my stereoscopic comparison test to youtube so you can takepart at home.

I have also put my survey questions online.

You will need the 3D glasses.

People that have inflenced my final video

solidscope — Mon, 28 Dec 2009 16:06:19 +0000

I have deicided that my final piece would be a 3D surrealist expearience that will be tested on a audience and asked if the 3D video is more real and a better expearience than the flat 2D video.

I am going to film while inspired by Marcel Duchamp and Man Ray

a look back (abit more research)

Thinking about projecting my project i look at verious ways of projecting in 3D. Most 3D movies project their features with 2 or more projectors by having two movies project through filters because some cinemas would have their own way of viewing 3D.

Just some earlier work that didnt quite make it.

This was the start of what i hoped would be the bases for a creepy 3D stereoscopic movie. However the detail of the insects was not good and i had to find another way of achieving my opjective.

I used After effects to create a gloomy room with a bit of light, using two cameras in AE to get the stereoscopic effect, then needed some insects so i started filming them on green screen but 1 the cameras i got were not the right quality (it was to low) and the green screen reflected on the shells of the insects so the green screen could not be keyed well. I also tried to put a computer generated fly in there but by the time i did one fly i was advised againest proceading with the whole 3D room idea, and so i started on the overhead filming of insects on a lightbox to get more of a contrast. However this did not work well and yet again i tried something new, i desided to use a 3D webcam i used to explore 3D stereoscopy with. The 3D webcam was low quality but the 3D works well so using the cam i recorded the kind of movie of envoke a responce and i also expanded my library to include other videos that may revoke other responces.

This was another attempt to film the insect, i filmed them from over head. I could not work with the footage as it could not be used to achieve a result.

Minoru 3D webcam is the way

My may tries at getting the DV Cameras to film stereoscopic videos has been mostly a failure. The problem was that the DV cameras are not ment for the stereoscopic vision, i tried repeatedly to get the right settings to shot well but the main issue was the lighting the perspective was not correct and most of my footage ended up looking like very bad 2D attempts at 3D.

I have to discided to use a stereoscopic webcam that will take most of the mountains away from the process.
At first i was too hug up on the quality of the films but a eventually got over this and as a lot of the problems with the footage i was filming became apparent.

The Minora 3D webcam allows you to focus in on a specific object.

Taking out a lot of the mountains involved in creating a stereoscopic clip and focus on the why i was making it.

The reason i was making it was because I want to ask people if having it in 3D makes it more realistic and see the audiences responses.

Screen to glasses to eyes to brain

I have known how these 3D glasses work and if you dont know this blog is for you.
Humans are born with two eye which is useful when using binocular vision which is used to tell the distance of objects with some accuracy. Using one eye to tell the distance of object can be done but it is slower and less accurate.

It is harder to catch a ball with one eye open then with both eyes, i have tried this and i advise you to try the same.

Both of your eyes see the world from a slightly different perspective because they are 2 inches apart and this is what is called the binocular vision system. The binocular vision system in your brain uses the difference to calculate distance and this is being done all the time. Using the two images captured by the eyes, the brain can pick out objects in the two scenes it sees and calculate how far the objects are.

Your brain has the ability to correlate the images it sees in its two eyes even though they are slightly different. The correlator can pick out objects in the two scenes it sees and calculate how far apart an object is between the two images. Objects that are farther apart in the two images are closer than objects that are not so far apart.

HowStuffWorks “How do 3-D glasses work?”. Available at: http://entertainment.howstuffworks.com/question360.htm [Accessed October 10, 2009].

The stereoscopic vision system uses the same principles and using a flat image the eyes can be shown different perspectives.

When watching a 3DS movie, you wear 3D glasses so the glasses can filter out the video before it reaches your eyes. In a 3D movie the screen is displaying two images. With the glasses the eye see a different image to enter one eye and the other image to enter the other eye.

The system i have been working with is Red/Green or Yellow/Blue. Two images are displayed on the screen, one in red and the other in Green, the when you see the image each lens will onlt pick up one image therefore it can be used to add perspective to a otherwise flat image.

Another techneque is Polarization but Polarization cannot work on an ordinary TV screen, so the red/green system is used.

Here is a thought of from was i earlier wanted to active but…

but… i came across some big technical issues like video quality.

In Up, the 3D effects are used like colours – they are vibrant when Carl is upbeat, muted when things go wrong.

“When he’s with [his wife] Ellie at the beginning, his life is rich and dimensional and so is the 3D,” says Whitehill. “When he’s alone, we really flatten out the 3D and make him feel trapped and claustrophobic. Then when he goes on the adventure, the 3D broadens out again.

“So if we’ve done our job right, we’re mirroring the other visual cues that have already been put into the movie – composition, lens choice, colour palette and so forth.”

I have started verious clips designed to create a responce, taken from different movies and short films it will hopefully enable me to come to a conclusion.

My tests of distance

solidscope — Wed, 09 Dec 2009 23:06:36 +0000

Embedded videos can only be viewed in 3D in youtube.com
I tested distance in stereoscopic 3D on youtube to see if there were any issuses i would have to deal with dealing with distance. Or if there was a distance that would be best to film in.

Longrange

Filmed at a distance of 3 metres

Midrange

Filmed at a distance of 2 metres

Closeup

Filmed at a distance of 1 metre

Moving towards camera

Moving away from camera

I have come to the conculsion that filming at close range is delivers the best result for what I aim to attachive.
