Shame on you Geoegress, this is the POSER forum :) And I'm lazy, trying to do all in Poser, no post-work heh. Actually I'm also relunctunt to load up a memory hog like PS, even if I close it afterwards, I'm never sure all the RAM is given back unless I reboot. 

Another reason is I save my renders as jpgs usually, and that means compression (75%) and loss of data. If I use the image in Photoshop and save it again as jpg, that's a second compression and loss. I'm a bit relunctant to do that also, I would need to planify more and save the pictures uncompressed I suppose. Bit of a hassle.

I read somewhere that there was a mathematical way to do random freckles in Poser but can't seem to find that info anymore.

Anyway thanks to everyone for the links, you're really all vey helpful, nice community here :)
