This week's episode is probably the most important one we've ever done. As such, the stupid jokes have been put aside (well, most of them) and the punk music has been replaced by something more respectable (for now); we've gone all serious. And that's because we're talking about the real future of film photography: the home darkroom.

From this moment on, it is our personal mission to encourage as many people as possible to beg, borrow or steal an enlarger, tape cardboard panels over their windows and make all their neighbours think they're running either a brothel or a meth lab. Yes, you too can end up on a government watchlist - it's really quite simple, and we're here to tell you just how simple it is.

Moreover, we're announcing our new feature here at www.pdexposures.com; the Red Light District. From this very moment we're taking submissions at [email protected], so send us photos of your own personal darkroom - with a short piece of text explaining some of the most salient points of your setup - and help inspire film photographers who may have been sat on the fence about going that extra mile and making proper silver prints instead of shoddy inkjet ones. Keep an eye out for the first instalment in the next couple of days; we start with either Nate or Tony, depending on who gets their post sorted first.

The music this week was provided by Rainbow Chow, the lovely wife of the infamous Hong Kong photographer and gearhead Dan K., and the song should be recognisable to anyone. So if you want your own copy of her version of Ain't No Sunshine, track down her latest album (Colours), or beg Dan for one.
