i'm quite new to paint.net and i've been trying to figure out how to apply a pinhole effect for a while. i read a blog and i followed steps, however, this required using the feather tool, but the radius only goes up to 10.
for example, this is an image that i edited on gimp. the feather radius goes up to 100, but an even larger radius would be more useful.
before
after (applied b&w and added some grain, but the pinhole effect is clear anyway)
Is there a Pinhole plugin out there? or alternatively, is there such thing in Paint.NET for the feather radius to exceed at least 100? if not, i would like to request these.
