Film Response Curve Recovery; Film response curve is a function maps from observed pixel values on an image to the log of exposure values: g(Zij) = ln(Ei) + ln(tj). To recover function g, we implement equation from Debevec. g is the unknown response function WebbCreate a high dynamic range (HDR) image from a set of low dynamic range (LDR) images that share the same f-stop but have different exposure times.
