Geoff Comfort

I found Geoff's talk to be quite boring honestly, and he mainly covered stuff that had been covered by other speakers, such as pricing. He is quite a good industrial and architectural photographer, but the main point I seemed to get out of his speech is that you can take pretty average photographs, and still get paid for them.
As he is an avid member of the AIPP, he also talked a lot about how it can help you get work etc.
