Yep, I'm aware of the Charles Jones story and his work. I think it's astonishing. I think Leon first mentioned him to me a few years ago. I've been meaning to buy that book ever since, so thanks for reminding me. I will go and add it to one of my many lists
Re the WWI photos mentioned above; I'm not saying the photographer has to be a pro - even though I still think it's the most likely scenario. I'm just speculating that it's unlikely he/she was a farmer (or possibly anyone in full time employment) given that these photos were taken during daylight hours and there are hundreds of them. I'm pretty sure that farmers in the 1910's worked long and hard most days of the week. Not all the pictures are particualrly good and this does indeed point to a hobbyist, but the sheer body of work makes me think twice about that.
Anyway, we'll probably never know...but at least I got a reminder about the Charles Jones book. Hurrah!
