    Why Do Aerial Images of Earth Appear Blue Despite Equal RGB Scattering?

    All three points are on the same vector - the angle is zero.

    Why Do Aerial Images of Earth Appear Blue Despite Equal RGB Scattering?

    The sun is at the Zenith and the detector is looking straight down towards the ground.

    Why Do Aerial Images of Earth Appear Blue Despite Equal RGB Scattering?

    It is common knowledge that the scattering of blue photons by the atmosphere is more significant than for other colors hence aerial images of Earth look bluesh. The graph below obtained from MODTRAN 'allegedly' supports this fact. While trying to quantify this effect, I've preformed several...

    "Black sun" effect in CMOS sensors

    Hi, I would like to understand the reason for the "Black sun" effect that occurs in CMOS cameras (very bright spots appear as dark). Thanks, ALex

    Broadening of emission peak - "red/blue spike"

    As I understand, spectral emission peak can broaden due to high temperature of the emitter. For example, emission of "cold" CO2 will have a thin peak at 4.3um while the CO2 emitted from a (very hot) rocket plume will have a broad emission at ~4um - 4.7um (called "red/blue spike") What is the...
