I don't print myself, and so I don't feel entitled to write to the journalist.
If I did, I would.
I would just amicably stress that contract sheet printing, and traditional printing, is not a "lost tradition", is something that is quite alive and well. Traditional photography is still alive. These kind of articles contribute to build the idea that traditional photography is something of the past. No surprise people asks if they still produce film.
Although I can feel a certain "sympathy", in the writing, for traditional photography, it is just another nail in the coffin. Raising, in the news world, awareness that traditional photography is still alive might help. A newspaper article like this could have been written with less "pathos", the "oł sont les neiges d'antan?" rethoric, and could have raised in the reader love, respect and curiosity for a technology which is still perfectly actual.
