About a year ago I used a nifty little program (or plugin) that was able to stretch the background of a picture (e.g. nature) while the foreground would keep having the correct aspect ratio (e.g. a person). This program worked really well, but I have lost track of it and am unable to find it.
I hope the description of this program is clear. If you know what the name is of this program/plugin, please let me know!
