Michael and Mark,
I came to the Brisbane Wildlife Workshop a complete beginner, armed with a digital SLR that I had no idea how to use.  I came away with some great photos but more importantly with a much better idea of how to use the aperture and ISO settings, light metering and flash to achieve good photos without having to rely on the camera's automatic settings.  Michael and Mark pitched the level just right - going through the basics with me one minute, and more complicated stuff with the more experienced photographers on our course the next.  I would recommend this course to aspiring photographers of all levels
