Daniel Reetz pointed me to this new preprint that instantiate item 5 in the These Technologies Do Not Exist section, i.e. Imaging Earth using the Moon (see here, here and here for some background on Nuit Blanche). The authors do even more and this is fantastic!
Here is the paper: Diffuse Reﬂectance Imaging with Astronomical Applications by Samuel W. Hasinoff, Anat Levin, Philip R. Goode, William T. Freeman. The abstract reads:
Diffuse objects generally tell us little about the surrounding lighting, since the radiance they reﬂect blurs together incident lighting from many directions. In this paper we discuss how occlusion geometry can help invert diffuse reﬂectance to recover lighting or surface albedo. Selfocclusion in the scene can be regarded as a form of coding, creating high frequencies that improve the conditioning of diffuse light transport. Our analysis builds on a basic observation that diffuse reﬂectors with sufﬁciently detailed geometry can fully resolve the incident lighting. Using a Bayesian framework, we propose a novel reconstruction method based on high-resolution photography, taking advantage of visibility changes near occlusion boundaries. We also explore the limits of single-pixel observations as the diffuse reﬂector (and potentially the lighting) vary over time. Diffuse reﬂectance imaging is particularly relevant for astronomy applications, where diffuse reﬂectors arise naturally but the incident lighting and camera position cannot be controlled. To test our approaches, we ﬁrst study the feasibility of using the moon as a diffuse reﬂector to observe the earth as seen from space. Next we present a reconstruction of Mars using historical photometry measurements not previously used for this purpose. As our results suggest, diffuse reﬂectance imaging expands our notion of what can qualify as a camera.
Maybe it is time to update both the Imaging With Nature and the These Technologies Do Not Exist pages. Thanks Daniel.
