Another local photographer that I know is also building a new darkroom (his 4th) and has decided to blog the effort. It is an interesting project (beyond just being a darkroom) because he is building "portable". Having had to move residence several times, he tired of starting over each time with a darkroom, and so is converting an old travel trailer that he can take with him - not to mention "on location" one would suppose.
Anyway, here's the link: http://notamethlab.wordpress.com/
I've also added a link on the Other Links page to another photographer whom I "know" only on the internet. She, too has been blogging construction of a darkroom, and is finished!
