As for many of us on the Forum, a huge part of my enjoyment of the IF and the larger world of Imperial Russia, say ca. 1860 to 1920, comes from photos of them (as well as by them.) In fact,it's almost impossible to think of them without visualing them at a given time and place and setting. I think with the profusion of photos of the Romanovs with which we're blessed, it's easy to take for granted how remarkable they are in a way.
I mean this in both a technical, as well as an impressionistic sense. Even to me in the digital age, the quality and clarity of many of these photos are amazing. Depending on one's age and sense of history ,the period 1895-1920 can appear as nearly ancient history or our grandparents' , even our parents' time. And yet these photos convey often a wonderful sense of immediacy, even modernity in a way.
Getting a true feel for OTMAA seems especially unimaginable without those pictures of them as infants, toddlers, children, and teenagers. Although writings by them and about them may remain paramount, I set great store in what I can read in the details of their faces, stances, clothes, others in the photo, etc. The early 20th century, so remote in some ways , is made incredibly close for me , by these photos that to state the obvious , provide a literal glimpse of the IF's lives.
I haven't addressed the technical aspect of that photography simply because I can't fully appreciate the technological details, about which I invite comment as well.
