The stack shows BOSMINA LONGIROSTRIS (Crustacea Cladocera), a water-Crustracean of about 0.5 mm length. The raw data (grayscale images) were generated with a Zeiss LSM 410 inverted confocal microscope. The animal is autofluorescent at a wavelength of about 540 nm. Notice attenuation of the emitted fluorescent light at the right lateral of the animal. The original stack size was about 80 slices. Processing of the rotated views: raw TIFF images were imported into Image 1.52, stacked, noise reduced and contrast enhanced. Projection was done every 6 degrees angle increment (value about possible stereo pair angle), rot. along y-axis, brightest point method. Depth cueing and other settings standard. Generation of the Stereopairs: An Image at x degree rot. angle was imported into the green channel of a Photoshop RGB Color Image, the image at x+6 degree into the red channel, blue channel filled black. The resulting 24bit RGB red-green stereopair was mode-changed into indexed colour, 8 bit, system palette, diffusion dithered. This was done for every 6 degree step image pair within 90 degrees. The images were duplicated and numbered in reverse order to get the back movement in the following stack process. A similar processing was discussed in autumn 1993 on the NIH-Image list. The now 8bit reduced stereopairs could be imported into Image.
