I often wondered why NASA publishes grey-scale photographs with the grid overlay, until I found out about the Bayer-Filter that they apply to colour/color photographs to convert them to grey-scale.
Here I present a step-by-step guide on how to decode or convert Bayer-Filter grey-scale/B&W encoded Mars rover photographs to colour/color using DaVinci Resolve and custom DCTL scripts.

I also show you the Analyst’s Notebook where you can find colour/color photographs that have already been decoded. Analyst’s Notebook links to the NASA Planetary Data System (PDS) and is a tool used by the scientific community, so it is an official tool with direct links to NASA.

IMAGE UPSCALING:
To see more examples of how well this image upscaler works and to read about the technology used please refer to the following web page:

Topaz Labs’ Gigapixel is not the run-of-the-mill free AI image upscaler. It is an expensive piece of sophisticated software used in studios and by professional photographers around the world, even NASA uses Topaz Labs upscaling technology.

DISCLAIMER:
Many or all of the anomalies/artefacts covered in this presentation may be naturally occurring geological features caused by some type of geological processes, however due to the lack of specific information from the source we can only speculate whether these are all natural or some artificial in nature.
In cases where I say an anomaly looks like something I’m attempting to clarify what I see and not specifically that the anomaly is what I say it looks like.
My intention is only to share anomalies I’ve discovered on Mars and not to convince anyone that there is or was a civilization on Mars.
