Analygraph or 3-D (three-dimensional) images are composed of two overlapping pictures of the same image, but at slightly different angles and two different colours. The images appear in 3-D when you're wearing glasses with two different-coloured lenses.

Photoshop or any photo editing software will work for creating 3-D pictures

Instructions

    Taking and Editing the Picture

  1. 1

    Pick a subject and a setting with a lot of angles and depth. A blank canvas such as a wall is not recommended.

  2. 2

    Take a picture approximately 15 feet away from the subject while you and the subject -- if it is a person or animal --are completely still.

  3. 3

    Move slightly to the right -- about 3 inches -- and take another picture. Transfer photos to a computer.

  4. 4

    Open both pictures in a photo-editing program. If the pictures are colour images, change them to grey scale by opening the "Images" menu and selecting "Mode," then "Gray scale."

  5. 5

    Assign channels to the left eye image by selecting "Mode" and then "RGB" while still in the "Image" menu. Click on the red, green and blue channels and exit without changing the right image.

  6. 6

    Select the left photo, select the "Window" menu and then "Channels." Click on the green and blue channels. Select the right photo, click "Menu" and then "All."

  7. 7

    Go to the "Edit" menu and select "Copy." Select the left photo, click on the "Edit" menu and select "Paste." The right photo is now layered on top of the left photo.

  8. 8

    Select the "Image" menu, then the "RGB" channel. The "RGB" should show an eyeball in each of the channel boxes. The image should be a blurred blue and red picture.

    Aligning and Cropping

  1. 1

    Highlight the red channel in the channels display menu (it should be shaded blue). Click the square box to the left. An eyeball should appear in all four channel boxes, but only the red channel should be shaded blue.

  2. 2

    Pick a focal point in the image to match up the right and left images. If a person or an animal is your subject, eye pupils or the nose is a good focal point. Zoom in on the focal point by clicking on the tool bar menu, select the magnifying glass, then click on the focal point until the view is very large.

  3. 3

    Select the "Move" tool in the upper right corner of the tool bar. Use the up and down arrow keys to slide the red-tinted focal point over to match the blue-tinted focal point. Zoom out.

  4. 4

    Clean up the image by cutting out any extra red or blue colouring at the far edges of the image by selecting the tool bar menu and outline the undesired excess colour.

  5. 5

    Select the "Image" menu and click on the "Crop" tool. The image should be ready to view with tinted bicolour 3-D glasses on-screen or after being printed.
