Maybe there's more than meets the eye when it comes to comets.

What if the camera broke and it's taking black and white pictures
[QUOTE=meppers;46707763]What if the camera broke and it's taking black and white pictures[/QUOTE] it must be entering the instagram phase by then, oh no
[QUOTE=meppers;46707763]What if the camera broke and it's taking black and white pictures[/QUOTE] As far as I understand it it's a monochrome camera. By adding red, green and blue filters they can capture information for only one colour of light, which can then be composited to give a full colour image. I guess they know it's working as there is some variation between the filters instead of it being completely identical, though that's just me guessing.

[QUOTE=A B.A. Survivor;46708489]Why isn't there a color camera on the probe?[/QUOTE] Field Sequential color systems are generally higher quality, plus it's not rocket science to do.

[QUOTE=Sableye;46708649]they can get better detail using false-color which is an approximation of what it should look like, i imagine the lighting is very weird anyway[/QUOTE] The lighting is very predictable. Why would it be weird? It's just direct sunlight.
[QUOTE=Sableye;46708649]they can get better detail using false-color which is an approximation of what it should look like, i imagine the lighting is very weird anyway[/QUOTE] the filters will pass through a known band of light, and the spectral distribution of the incoming light to the surface is known as well. by combing the images they can get a perfectly accurate image. imaging space is actually easier than imaging in an atmosphere because there are less variables at play like local color affecting white balance false color images don't usually attempt to replicate what the true color should be, rather they attempt to make certain features of the subject correlate to colors, like a temperature map or heightmap or whatever.
What if it was clear, would that be weird or what?
How are they sure it's not secretly a black-white photo if its all grey & black :tinfoil: [sp]yeah yeah yeah[/sp]
