Tuesday night saw us being thoroughly entertained and informed by 'our very own' Terry Hewitt with his presentation entitled Camera RAW: What, Why and should I bother. Terry began with an overview of how digital cameras capture images and the RAW format that results.
He also went in to some detail on colour, showing how there can be colours visible on a screen that cannot be reproduced accurately on a printer, say, and the different colour spaces that are around such as sRGB or AdobeRGB.
He pointed out that you can either let the camera do this conversion for you to produce a JPEG image or you can get the RAW format which you then have to process on your computer with programs such as Adobe RAW or Lightroom.
After the theory there followed a much needed tea break! Terry then proceeded to demonstrate the wide variety of operations you can carry out and all in a non-destructive manner. That is, if you make a total mess of things you can always go back to the original RAW file because that never gets changed.
Some of the things Terry talked about were quite intellectually challenging, but then that's what made it so interesting, in my view.
