David j. gave a short presentation to the Acorn Photographic Society, Ballaghadereen on the History of Photography from the humble beginnings up to the first colour image. Although not extensive he covered the first permanent photo ever taken (Joseph Niéphore Niécpe - 1827) through to Daguerreotypes and Fox-Talbot's Calotypes whose Positive/Negative process was the foundation of modern photography.
The first colour photo was a virtual image. A still-life was photographed three times in B/W using Red Green & Blue filters, then projected onto a wall with the three corresponding filters in front of each negative. The over-lapping image was in full colour. As the pioneer J.C. Maxwell was scottish the image he chose was a tartan ribbon.
I received the following e-mail from the club secretary:

given me to pass on to you. Everyone really enjoyed the the history and asking
