I have been importing all my digital images into my Adobe Lightroom photo cataloguing programme and I discover that, so far, there are 33,550 of them. A quick calculation shows that this is, on average, about 1.4 photographs per day of my life, which is hardly excessive. Using a random number generator I choose one image out of the 33 thousand to use as an illustration. It turns out to be a picture taken in Bangor, North Wales in November 2009. I suppose I should also show .4 of another photograph to illustrate my calculation, but that would be silly : and I am certainly not silly - am I?
