[quote="dnmilikan"Does anyone know his age?

Not off hand but I may be able to make a guestimate from one of his books. Whatever individuals' opinions of Barry were (and I do not hold any because I never met or spoke to him although I have bought chemicals from him and bought his books ) he did try to make people who were interested enough to read his books, think about their photography and the materials they were using so that they could get the results they wanted and the photographs they had visualised. Les also does this in his own style which is different to Barry Thornton's approach. We are all influenced to some degree by the knowledge and experience of others when it is imparted to us and Barry will be missed, not least by those who have attended his popular workshops.
