CD / Blur

Captain Disillusion explains how blur works and how it can be reversed, in his visual-effects explainer style. He uses the Fourier transform and deconvolution to show how the ENHANCE trope relates to real image processing.

HN recommends it as an excellent visual illustration of how the Fourier transform works, and as a popular-science take on blurring and unblurring.
