If you are signed-up to Groupon, there a 20-module photography course available for £14 (full price was £295). I saw that some of the modules are probably quite basic for us, but there are specific modules on landscape, creative, night, sport, studio, fashion, travel, etc that may have some handy tips. I thought it was worth a punt. Here's the link to Groupon...
