Photography courses

I am thinking of doing a part-time evening photography course.

I want something that will inspire me to take more photos in and around London, and help me learn techniques for taking photos in difficult situations (poor light etc).

Sadly most of the courses seem to involve lots of black and white darkroom techniques (something I have zero interest in) are very expensive (upwards of £1500), or take place during the day.

If anyone knows of any decent photography courses in South or Central London that fit the bill, drop me a line please.
