Time machine..

Oh, my God, Doctor, what is it? A kind of Tardis? Have aliens finally landed? Who is that giant woman? And what does Kodak mean?

Keep calm, son! That's not a space-ship, it's an enlarger! A what, Doctor? An enlarger, dear boy! A Vivitar colour enlarger. Believe it or not in the old days, if you wanted prints, you had to lock yourself away for hours in a dark room with one of these bad boys and bucketloads of smelly chemicals! Oh, wow Doctor, so it is a Tardis - it's a time-machine from photography long ago! Ha, yes, my son, I suppose it is. That and the Kodak sign. Kodak were one of the companies that produced the paper to make the prints, you see. Ah, yes, they're all signs of an era long ago and far away and, do you know, that enlarger's gone from having a price tag of £393 in this photograph to being sold on ebay last week for £19.99. Old technology, see. Wow Doctor, that's amazing! But, doctor, one last question. Yes, my son? What's a print?
