I know that good artists work on their craft every day -- that's how they become great. We don't get to see the poor results from artists -- just the finished works that they are happy to finally show. Since Sally is working with collodion, it's a much more pain-staking process, with many variables to consider. Sally's description of her feelings about working on her portrait work made me mull that around in my head long after her lecture.
This was a very memorable lecture - thought provoking, introspective, and educational. I think that if some us came out feeling a little humbled, then that is a good thing.
