Reduction of image blurring on individual aerial photographs

A technique is discussed for photographic reduction of blurring which utilizes only a single photograph. No special equipment which is not available in practically any photographic laboratory is required to carry out the technique.

Applicability of the diffusion approximation

Several methods using an approximate form of the scattering indicatrix are discussed for simplifying the calculation of radiation transport in planetary atmospheres.

Estimates of the Venus atmosphere optical characteristics with application to the problem of photographing its clouds and surface

Optical parameters investigated and solved for included: (1) cloud layer albedo and cloud cover optical thickness; (2) planetary surface self-radiation influence; (3) light flux distribution as function of atmospheric height; (4) upper estimate of the observed contrasts; (5) surface optical parameters; and (6) contrast decrease with altitude.
