On Thursday 18th September our second night of the season was dedicated to “how the camera works”. Unfortunately, Vic was unable to give his prepared talk due to ill health (although I am glad to say, he is now in better health). Fortunately Tony Mitchell was able to step in with an interactive demonstration of the basics of camera operation.
Tony’s lecture covered the basics of how the human eye and brain see (perceive) our surroundings and how this can be translated into an understanding of how a camera works. The topics covered aperture, shutter speed and ISO.
The effects these 3 factors have on an image were demonstrated with a live setup and some practical, hands on, advice on using these settings.
