Thanks for your alert. And thanks too for making a start on some on the comments. I'm a bit pressed for time today but will see how things go. The most difficult comment to deal with is "There is no underlying theme, apart from the Danish connection. I am not getting any real feel for the subject. There is little about the development of the photography industry in Denmark, apart from its beginnings." The article is not about the photography industry but about photography as a means of expression. It is of course true that Agfa Gevaert had a factory there for a number of years but it was only one of many. I think I'll have to explain this.
