A large part of the course was in Borough Market. The instructor made a big deal of getting the light right at the start, Use manual mode. Use metering, Take a load of pictures of absolutely anything just to get the settings for the camera right before you even start to take the pictures you want to take. For me, I initially really struggled with this – I have a really bad habit of just reverting to Aperture priority and letting the camera do the work. However, the instructor showed us quite a few photos that had been taken on Auto, compared with photos taken when the photographer had chosen the settings, and the latter were substantially more atmospheric, every time.
