StereoScop3

Stereoscop3 - create three dimensional photographs with your iPhone.

Stereoscop3 allows you to easily take photos with your iPhone to create three-dimensional images including cross-eyed, wall-eyed and anaglyph images. With practice, you can take and view images quickly and easily.

Quickstart

Here are the quick instructions for those in a hurry:

1. Launch Stereoscop3.
2. Select a suitable scene (see below for more details on scenes).
3. Touch the screen to display the controls.
4. Use the Left button to take the first image, placing the crosshair on a fixed object in the foreground.
5. Use the Right button to take the second image, placing the crosshair on the same place as in the first image.
6. Use the Mode button to choose the viewing mode you prefer.
7. Retake images using the Left or Right buttons until you are happy with the result.
8. Use the Save button to retain the images in the Library for future viewing. Warning: If you don't save the images they will be lost if you take new images, load a set from the Library, or relaunch Stereoscop3.

Taking three-dimensional images

Creating effective three-dimensional images requires that you carefully select a suitable scene, frame the images carefully, and then take the images. Most people will need to practice in order to get the best results.

The most effective images contain a focus point near the centre of the image which sits in the foreground of more distant objects. People sitting in front of a vista, or objects arranged on a table can work very well. It is very important that the majority of the image remains unchanged between the two photos, too much change will confuse the vision processing area of the brain and ruin the illusion.

Choose a point near the middle of the image. This will be used to ensure the two images are lined up. The brain can compensate for a reasonable variation in horizontal movement when creating the three-dimensional illusion, however small amounts of vertical difference will ruin the result.

Touch the screen to show the controls, and use the Left button to bring up the camera interface. Line the cross-hair up with the focus point you have chosen. The cross-hair is positioned to help take photos of near objects , the small vertical bar to the left of the cross can be used to line up with more distant objects. Use the Take Photo button to capture the image, which will then appear on the screen, positioned according to the display mode you are using.

Repeat the process using the Right button , positioning the same point on the cross-hair (flipped as we are changing to the other side) on the same focus point you used for the left image.

Compare your images. You should see a similar image in both, with one offset slightly (left or right) from the other, but with little vertical offset. If the images are vertically offset, use either the Left or Right button to retake the until you have the images lined up.

If you're happy with your images, you can save them using the Save button . Warning: If you don't save the images they will be lost if you take new images, load a set from the Library, or relaunch Stereoscop3.

When a set is saved in the Library, you can use the Edit button to show the name and images and edit the name.

Viewing three-dimensional images

Images taken from the camera or loaded from the Library are viewed on the main panel of Stereoscop3. Initially this displays a placeholder image for the left and right images, and these are replaced with your images.

Stereoscop3 version 1 supports four different modes of three-dimensional display, selected using the Mode button:

• Wall-eyed
• Cross-eyed
• Red-Blue Anaglyph
• Green-Magenta Anaglyph

Anaglyph images are generally easier to view, but require the use of coloured glasses and the images appear monochrome. The Wall-eyed and cross-eyed images are full colour and require no additional equipment but require practice to see easily.

Viewing Wall-eyed Images

In this mode, your left eye views the left image and your right the right image.

Load the images and select the Wall-eyed mode . If you want to practice, here is an example:

Hold the iPhone screen close to your face and allow your eyes to notice a prominent feature in the centre foreground of the image - it will appear blurred at this point.

Move the screen away from your face slowly, trying to not move it up, down, left or right.

As the image moves away from your eyes, try to bring the feature you selected into focus without moving your eyes.

Repeat until you can see a single image in focus between the two blurred left and right images. This will take some practice, but once you have the trick you can easily and quickly view images without taking these steps.

Viewing Cross-eyed Images

In this mode, your left eye views the right image and your right the left image.

Load the images and select the Cross-eyed mode . If you want to practice, here is an example:

Hold the iPhone screen at a comfortable distance from your face.

Hold a finger up between the screen and your eyes, in the centre.

Focus on the finger. The images on the screen in the background will join in the middle to form a blurred image.

Slowly let your eyes focus on that central image, moving your finger out of the way when it starts to focus.

Repeat until you can see a single image in focus between the two blurred left and right images. This will take some practice, but once you have the trick you can easily and quickly view images without taking these steps.

Viewing Red-Blue Anaglyph Images

In this mode, your left eye views the Red part of the image and your right the Blue part of the image. You will need a set of Red-Blue glasses such as those listed here.

Load the images and select the Red-Blue Anaglyph mode . If you want to practice, here is an example:

Put on your glasses, with the Red lens over your left eye and hold the iPhone a comfortable distance in front of your face. The three-dimensional illusion should be apparent immediately.

Viewing Green-Magenta Anaglyph

In this mode, your left eye views the Green part of the image and your right the Magenta part of the image. You will need a set of Green-Magenta glasses such as those listed here.

Load the images and select the Green-Magenta Anaglyph mode . If you want to practice, here is an example:

Put on your glasses, with the Green lens over your left eye and hold the iPhone a comfortable distance in front of your face. The three-dimensional illusion should be apparent immediately.

Stereoscop3 Controls
