[Regex]how to excludespecific filefromregex

Hi,

as i can't understandregex (seems likei'm stupid -.-) ihopesomeofyou could help me...

I'd like to have a regex that rewrites all hidden files (and directories) to 404,BUT files named ".album.jpg" in all directories.

The regex for rewriteingall hidden files to404 is this:

rewrite ^(.*)\/\.(.*)$ @404 break;

i tried it with this. but it didn't work:

rewrite ^(?!(album))(.*)\/\.(.*)$ @404 break;
