True documents

From Searching for Sebald (Photography after W.G. Sebald): 
"You have a very real nucleus and around this nucleus a large empty space. You yourself don't know the context for the depicted person and which landscape it is. Is it Southern France, is it Italy? You don't know. And you have to start thinking hypothetically. This track inevitably leads you into fiction and to storytelling. When writing you recognize possibilities: to start by drawing out stories from the images, to walk into these images (erzahlend hineinzugehen) through the telling of stories, to implant these images into a text-passage, and so on."
"The photograph is the true document par excellence. People let themselves be convinced by a photograph." 
Sebald is arguably one of the most relevant writers to quote on the sensibilities of mixing photos with fiction; of the former's relevance to the latter; and, of how--during the process of writing (handwritten or mental)--the camera acts as "a shorthand or aide memoire.

No one can succinctly describe the regret of not taking a photo quite like Sebald. It's true: there will be days where you wished you had a camera with you, capture the moment, document it not through writing (it will come later). link
"Again and again there are situations when you think that this is impossible, that it cannot be, [situations] where you would really have to take this snapshot. For example, it happened to me recently at the Amsterdam airport: when I had to sleep there overnight because the entire airport was fogged in and none of the planes could take off, after midnight everyone was stretched out horizontally on these sofas on the upper floor of the departure lounge. They were covered with the kind of thin, blue blankets provided to the campers by KLM. An extremely ghostly scenario--human beings that, laid out like the dead, were lying curled up on their side or very rigidly on their back. And outside, through the windowpane, was the mirror image of the interior."
