3D stereo

Generates a three-dimensional image which can be viewed using red/cyan glasses, in cross or parallel view or with a KMQ viewer. These images can also be printed as usual.

To create such an image, the two source images must be marked in the thumbnail views, after which this tool is executed. If the the source has been taken using a LOREO lens, then a single source image is sufficient.

Horizontal This slider sets the depth of the stereo image. It is set according to the red and cyan colored margins or edges (also with cross or parallel view or KMQ viewer). Normally the depth is set so as to provide distinct regions in the foreground, on the monitor plane and in the background. Ideally, the objects which are on the monitor plane (virtual window) should be placed so that they match.

Vertical Sets the vertical offset which can occur with freehand shots. To  achieve the best impression of depth it is essential that the images should have the same elevation.

Note The horizontal and vertical image position can also be altered using the key combination [Ctrl] + arrow key.

Rotate Rotates the two images with respect to each other so that the rotation which often occurs with freehand shots can be corrected.

Ri/Le swap Interchanges the two source images to obtain the best possible impression of depth. If the source images are stored in the wrong order then all objects which are supposed to appear in the background actually appear in the foreground.

Outline Superimposes the images on each other so that the relationship to the virtual window can be set using the outline.

Color selector and distance Here, a color and the 'distance' in % between the images can be defined. This provides a point of reference for the eye. Applies only to parallel and cross-view as well as KMQ output.

Viewing method selection After the viewing method has been selected it is implemented for  the preview. For adjustment of the partial images Outline should be activated.

[1] Color anaglyph Generates a colored red/cyan image which can be viewed using red/cyan glasses.

[2] Half tone anaglyph Generates a colored red/cyan image in which the red tones are diminished. This is useful for images which are intended to remain colored, but have overemphasized red tones.

[3] Grayscale anaglyph Generates a grayscale anaglyph after the glasses colors have been set. This can also be viewed with red/green glasses. Useful for overstrong red or yellow tones.

[4] Parallel view Generates two adjacent images which can be viewed using the parallel view technique. The color and distance shift between the images can be set at will.

[5] Cross-view Generates two adjacent images which can be viewed using the cross-view technique. The color and distance shift between the images can be set at will.

[6] KMQ Generates two adjacent images which can be viewed using a KMQ viewer. The color and distance shift between the images can be set at will.

[7] Save images individually After the storage location has been entered the images are individually saved.

Hint for saving color and grayscale anaglyphs: The best results can be achieved by storing the images using PNG format. However, this can result in very large  file sizes (500KB and above). If the image is to be stored in JPG format, the best solution is to use JPEG subsampling, setting it to 4:4:4.  The image then requires somewhat more file space than usual (using 4:2:0), but the so-called 'ghosts', i.e. color overlaps from the source images, are minimized.
