There are some details, like the litter bean, the shoes or the type of glases, that show us the photo is actual. But there is one especially, that don't fit into this atmosphere of ancient image. This one it's that the old woman, show us her knees. Sepia techique is so strong associte into our minds to the ancient techniques from early photography, ancient poses and past times, that this is the true reason for feel it haves "a nostalgic atmosphere" . Precisely for this reason, i think that to apply this technique to a "modern" olders, is not addecuate at all. I think that only with B&W have was enough.
