The raw material here is digitized versions of analog photographs, so hybrid is appropriate. The photographs are vintage and this is the "antiques" section where vintage photographs are often discussed.
[Edit to add: this antiques forum is in the "general discussion" area where all workflows are explicitly allowed.]
To the question of whether colorized photographs are faking it. I often find the practice to be kitschy. However, a powerful argument for it is made by Peter Jackson's recent film on World War I, "They Shall Not Grow Old." It is made almost entirely from colorized vintage photographs and movies (yes movies during WW I), and with a voice-over that is re-recordings of the reminiscences of WW I veterans, no contemporary talking heads.
Jackson's argument (my paraphrase) is that our standard view of the war through B&W still photos makes it seem like a far-away dead historical event, and that bringing color to the movies and pictures reinforces that it was a vivid experience that happened to people not unlike ourselves, now only just beyond the grasp of living memory. IMO, it works both artistically and as history.
I highly recommend seeing this movie for anyone interested in these issues of historical representation.
