Albedo formula_5 (also called blue-sky albedo) can then be given as: Directional-hemispherical reflectance is sometimes referred to as black-sky albedo and bi-hemispherical reflectance as white-sky albedo. These terms are important because they allow the albedo to be calculated for any given illumination conditions from a knowledge of the intrinsic properties of the surface. The albedos of planets, satellites and minor planets such as asteroids can be used to infer much about their properties. The study of albedos, their dependence on wavelength, lighting angle ("phase angle"), and variation in time comprises a major part of the astronomical field of photometry. For small
Albedo One generally ranged from largely positive to very positive. One reviewer stated that "if you're flatulently full with the fluffer shorts of pedestrian writers going through the motions, a dose of "Albedo One" #29 is the perfect antidote." The same reviewer stated of issue 32 that ""Albedo One's" inexorable rise to the top gains momentum with this issue's expertly assembled and fluid mix of speculative fiction." A review of issue 33 on BestSF stated of the magazine that "It's not quite up to kicking "Interzone's" arse, but as the redoubtable English mag takes strides forward under its new leadership, "Albedo One"
