Archaeology shares a great deal with photography. Particularly time and a temporality of actuality.
Here is how I descibe it in my wiki entry on the archaeological (also mentioned on 10 December).
Four archaeological temporalities:
Recollection
It is not only that archaeologists gather fragments and build collections. Like memory, the work of archaeology is re-collection – the reinsertion of pieces of the past into a form that carries significance in the present, carried forward from the past. As in memory, the (archaeological) traces of the past do not constitute a timeline or linear account. They resonate with a present experienced moment; this is what precipitates their reemergence, their recollection. This is actuality.
So photoblogs add a wonderful nuance – photos of everyday matters strung together in a sort of inderterminate (re)collection.

Philip@philosophistry (awesome blog) has a fine list of photoblogs (mostly in my minimalist taste). [Link]
