Tetbury Camera Club welcomed Vincent Knaus to our Zoom meeting last night. His talk was called ‘The Interaction of Colour’. What a evening! So different to any other speaker we have had. Our members were fully engaged and asked lots of questions. Vincent explained to us in words and with examples, of how we each see colour in different ways and the colour wheel. He also showed us how one colour in an image has an effect on all the others and how to use that to our advantage.
