Firefly Removal Filter 2

This is a small but potentially useful macro for removing extremely bright pixels out of your renderings. If your renderer is setup correctly you usually don’t have to deal with that kind of stuff but if you made a mistake and cannot re-render your images because the deadline is near and you’re running out of time this tool can come in handy.





Avoid very low threshold values. Once you reach the brightness of the average pixels in your image, everything gets blurry. A better way to go is having a higher threshold and string together several filters in a row.

      Hi, there are 2 easy ways to do it
      A) just drag and drop the file onto your fusion graph view or
      B) put the file to your “C:\Program Files\Blackmagic Design\Fusion\Macros” and it will show up in your rightclick menu under the “Macros” category.
