We present a learning-based method for synthesizing novel views of complex\nscenes using only unstructured collections of in-the-wild photographs. We build\non Neural Radiance Fields (NeRF), which uses the weights of a multilayer\nperceptron to model the density and color of a scene as a function of 3D\ncoordinates. While NeRF works well on images of static subjects captured under\ncontrolled settings, it is incapable of modeling many ubiquitous, real-world\nphenomena in uncontrolled images, such as variable illumination or transient\noccluders. We introduce a series of extensions to NeRF to address these issues,\nthereby enabling accurate reconstructions from unstructured image collections\ntaken from the internet. We apply our system, dubbed NeRF-W, to internet photo\ncollections of famous landmarks, and demonstrate temporally consistent novel\nview renderings that are significantly closer to photorealism than the prior\nstate of the art.\n
