Hi, again!

Now i have a dude about GIMP,. Are there some plug-in/script can blow-up and sharp the pictures like as "Alien Skin Blow-up" from Photoshop????

i have tried to get the same results with a Liquid Rescale and next apply the Warp-Sharp upon some pictures but Alien Skin blow-up has better results.

better result doesn't is too clear
if you just scale up will be needed something as greycstoration after (or selective gaussian blur or despeckle)

with liquid rescale that should be no so needed but that depend on how much you scale up.

Anyway i will use unsharpmask2 instead then warp sharp but maybe only because i know that better.

but without know how much you scale up and without see the image is hard say more
