Chandrayaan-3: ISRO's Stunning 'Anaglyph' Of Vikram Lander On The Moon

The Indian Space Research Organisation (ISRO) recently released a captivating "anaglyph" image of the Vikram lander on the Moon. This image was captured by the Navigation Camera onboard the Pragyan rover, which took photos of Vikram from both left and right angles. These images, collectively known as NavCam Stereo images, were used by ISRO to create the anaglyph.

In the realm of photography, an anaglyph is a composite picture that achieves a stereoscopic effect by overlaying two images of the same subject taken from slightly different perspectives and in distinct colors, often using red and green hues. When viewed through specific filters, this technique creates the illusion of three-dimensional depth.

In essence, an anaglyph is a way to visualize an object or terrain in three dimensions by utilising multiple images captured from different viewpoints.

According to ISRO, the Vikram anaglyph, generated from Pragyan's camera images, is a three-channel image, meaning it combines three different colors. However, only two images were used in its creation.

ISRO placed the left image in the red channel and the right image in the blue and green channels, resulting in a cyan effect. Because the two images offer distinct perspectives, they produce a stereoscopic effect.

To fully appreciate the stereo or three-dimensional effect, ISRO recommends viewing the anaglyph with red and cyan glasses.
