are these photos in B&W or is the comet really that gray?
- matheweis 12y agoProbably B&W. Even color images (aka like you see from the MER mission) are just a B&W imager multiple exposures - each with a different color filter.
- modzu 12y agowe're running spectrographic analysis etc but we don't know the color of the surface? it strikes me as strange we don't have color photos. is it to save bandwidth?
- clarkmoody 12y agoThe imaging sensors themselves will be monochromatic (B&W), so there are no color-detecting pixels. Some space imagers slide multiple colored filters in front of a single B&W camera to get colored frames. Those frames are later composited into color photos.
- grey-area 12y agoThey have some colour photos (taken with filters), they've already stated the colour of the surface (black or grey, it's really just not colourful).
- dandelany 12y agoWe will get color photos eventually - they're being taken, they're just subject to a 6-month embargo.
- Pinckney 12y ago"Some light contrast enhancements have been made to emphasise certain features and to bring out features in the shadowed areas. In reality, the comet is extremely dark – blacker than coal. The images, taken in black-and-white, are grey-scaled according to the relative brightness of the features observed, which depends on local illumination conditions, surface characteristics and composition of the given area." http://www.esa.int/Our_Activities/Space_Science/Rosetta/Highlights/Top_10_at_10_km http://www.esa.int/Our_Activities/Space_Science/Rosetta/High...
