A few years ago, I decided to attend a judging workshop run by the CACC. The primary intention was to improve my own self-critique, but I was surprised when it concluded to be asked to judge for the CACC in local camera clubs.
It's a great experience and you learn a lot - not just from the initial training but ongoing in visiting clubs and analysing images. I'd recommend it to anyone.
If you'd like to contact me regarding making a booking, my details are in the CACC handbook - or you can send me a message via this website.
Please note: I am taking a short break from taking bookings, as recently I find myself overcommitted and as a result my own photography goals are suffering.
