Art, I would venture to say that Perseverance is sending something akin to raw binary data back, that would allow greater areas of exploration of UV, IR and other parts of the visible and non-visible

Interesting zoom lens mechanism, but how can you get great looking bokeh on closeups of Martians at F/7? Noel Sterrett | Admit One Pictures | Atlanta

Here's a little more on the cameras, from a photo newsletter, PetaPixel: "A Closer Look at the Mars Perseverance Rover’s Incredible

>>>A grey card helps identify the white point of the scene. How the camera reacts to that is camera dependent. That’s a better way of saying that. And, as best I can tell, that’s just a gain

A grey card helps identify the white point of the scene. How the camera reacts to that is camera dependent.

I would guess RAW as well. Many of the same arguments I would offer in the design of this remote camera, could be used for the design of the cameras we use.

I would think it would send raw back. Processing the image before transmission seems like a waste of processing power and energy when you could do it just as easily on Earth, plus you can update the

>>>A grey card seemed to work well for a long time…. That’s because film has the color science baked in. If you print the gray card as neutral then everything else falls in line (depending on

Anyone know if it sends RAW back, or de-Bayer/process first?

The Mastcam-Z is a stereo multispectral camera system (references in increasing order of

While a grey card is a great tool, there is something to be said for a chart also displaying either red/green/blue or yellow/cyan/magenta. (Note the ‘also’ as a white/grey neutral reference is

Still does.

Thanks, great sites. Makes my chart knowledge seem totally inadequate. Maybe we should to move to using charts with only 3 or 4 colors? That's all NASA seems to need.

Here is a more descriptive article about the referred color calibration device, you may find hardware details there as well - its a 1600x1200 Kodak CCD (KAI-2020CM), with a set of 11 filters on a

And we all know the old joke… How do you find out if there is life on Mars? Ask any video engineer: Put a chip chart up and if there is life on Mars it will walk between the camera and the

No need to pack your color charts for a shoot on Mars. A few are already there: https://mars.nasa.gov/embed/25619/ Anyone know what sensor/color science they use?
