Ok, it's been a long time since my last entry, however I plan start blogging again.
I have recently been playing around with the Canon EOS Utility software which came with my EOS550D and it is fantastic for demonstrating lens parameters in realtime, so for lectures and training videos it works a treat. You can use the utility to control all parameters of the lens and camera such as f stop, shutter speed and ISO, together with a realtime preview which in realtime shows what effects changing these have on the image. A cracking tool for demonstrating basic lens theory.
