“As one-off fees, you might say, ‘that’s not so bad’. But consider that your average art history PhD will have dozens, if not perhaps hundreds, of images, then soon even an unpublished PhD can become prohibitively expensive. You want to discuss mid-18th Century portraiture, and show perhaps 50 images? That’ll be £750. You want to turn that PhD into a book? £3050 please, before you’ve even thought of printing costs. Want to put on a Hogarth exhibition, with a decent catalogue? £8600. Ouch. And Tate are on the cheaper end of the scale.”
