Computational bounce flash for indoor portraits

Advanced photographers address this problem by using bounce flash, a technique where the flash is directed towards other surfaces in the room, creating a larger, virtual light source that can be cast from different directions to provide better shading variation for 3D modeling. However, finding the right direction to point a bounce flash towards requires skill and careful consideration of the available surfaces and subject configuration. Inspired by the impact of automation for exposure, focus and flash metering, we automate control of the flash direction for bounce illumination. We first identify criteria for evaluating flash directions, based on established photography literature, and relate these criteria to the color and geometry of a scene. We augment a camera with servomotors to rotate the flash head, and additional sensors (a fisheye and 3D sensors) to gather information about potential bounce surfaces. We present a simple numerical optimization criterion that finds directions for the flash that consistently yield compelling illumination and demonstrate the effectiveness of our various criteria in common photographic configurations.by Lukas Murmann.S.M

Non-tax revenue and subnational democracy: evidence from Colombia
No full textAn influential group of political economists posits a negative relationship between the relative size of non-tax revenues in public balance sheets and the level of democracy in a given county. While empirical evidence for this proposition is largely based on cross-national studies, scholars have largely neglected subnational contexts as important domains of research. Addressing this disjuncture, the author studies the electoral impact of two important subnational non-tax revenues - natural resource royalties and central-government fiscal transfers - at the municipal level in Colombia. Employing a propensity score matching approach to attenuate problems of omitted variable bias, a quantitative analysis of Colombia's 1119 municipalities shows that higher levels of fiscal transfers and petroleum royalties had no discernible impact on the average level of competitiveness in the 2007 and 2011 municipal elections. If anything, there seems to be a positive impact of non-tax revenues on electoral contestation. Supported by qualitative evidence from theoretical outliers in the set of observations, the results suggest that non-tax revenue promotes electoral competition by raising the stakes of attaining political office. At the same time, abundance in fiscal transfers and resource royalties may undermine democratic governance through means that are not reflected in electoral margins.M.A.Includes bibliographical referencesIncludes vitaby Lukas Konstantin Kelle
