that is a link to a photo printed with a filed neg carrier(what I assume the poster is asking about)-(only this was actually done in a darkroom)
You can buy border actions "borderit" at
http://www.nitorix.com for $150 it comes with a few different borders- the filed neg carrier is one of them- Of course none of them will probably look as good as the real thing- but I am also looking to do this-without buying the actions-so if anyone knows how I could get this cheaper(or as freeware) as an action, I'd appreciate it...I'll try the steps listed above-but I think I'd rather have an action already made.
thanks
