WebImport Data¶. An FFT Filter is a process that involves mapping a time signal from time-space to frequency-space in which frequency becomes an axis. By mapping to this space, we can get a better picture for how much of which frequency is in the original time signal and we can ultimately cut some of these frequencies out to remap back into time-space. WebJul 2, 2024 · The example before/after GIF is using the FFT filter and then a tad of Camera Raw filter to take out remaining noise. Note that it is a 400% enlargement using next neighbor rendering so looks even better not blown up. Results similar to other FFT filters yet this one does most of the work for you (watch the YouTube video).
