Just a simple trick to remove fireflies only with one click without losing any details (But be sensible with the sliders !)
Render your scene, put the image to photoshop, choose the "remove dust & scratches" filter and that`s it.
Your will get an absolut acceptable result.
But i have noticed that the fireflies appearing only if you use transparency together with translucency.
So if you dont have to use translucency in you scene try to avoid this function and you wont have any problems with fireflies.
Is there anybody out there, who has made a different notice.
