It has been one of those days. First the traffic this morning and then no internet at the shop. After sorting that problem I receive a phone call from one of our supplier's reps wanting to call. Meanwhile we are busy in the shop and the phone doesn't stop so eventually I think what shall I do, I have no picture today. I took the original picture about 25 years ago on Ilford FP4, still my favourite black & white film, and I began wondering how long before all of our digital images disappear or become unreadable.
