There is a simple way to retouch fireflies in renders with just a few clicks.
This is not a substitute for a nicer render but good enough (especially for previews).
- Open the image in Photoshop
- Convert it to 16 or 8 bits per channel. The filter doesn’t work under 32 bits/Channel.
I suggest that you use the Exposure and Gamma method (Image->Mode menu).
- Filter->Noise->Dust & Scratches…
Threshold: something low (0-10)
Unfortunately the image will loose some detail (not that much, e.g. you can see it at the mother’s left hand).
