Truth? and Perception

To help you see the perceptual effects, the original stretched data is on the left, and the modified palette is shown on the right. Same image in both cases.

The red dominated image appears to have a hole near the pillar on the right. And the dark clouds also look like holes on the left. By manipulating our sensation of illumination we can enhance what we wish to present as a more 3-D structure of a pillar and floating dark clouds above.

For some reason it is easier to believe that deep red will be fading to nothingness, but light illuminated coloration will seem to present a back-illumination of an object.

The red image looks like a dying region, fading into oblivion. The bright image looks like an active pillar of creation, a sense that something new will be emerging.

The palette modification was performed by making a red color mask of chrominance in the image on the left, then using that mask to become the blue and green channels of another image that was added to the original image. Excess green noise was then removed with a green chrominance filter. All in PixInsight.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
