It's been done before - How can I create this 'medieval look' using an entry-level camera like the Nikon D3300? - which ended up being my single largest rep source ;)
This started out as a rather hopeless question, to which the OP never returned [though he did post one more 'what's this' type question later] but it had some interesting images with reasonable similarities & seemed worth a go. The current question was back-edited after the fact to prevent it just being abandoned to the basement filing drawer of history.
I think the end result was worth the effort - though I may be somewhat biased ;)
Another appeared recently - How do you get this sort of effect to which the OP has not returned. It's since been closed, as many of these are, as 'unclear'.
If we assume that what he wanted was advice on grain then we have an answer, which someone took the time to provide.
How do we feel about now back-editing it so it clearly asks what that answer provides?
I know we have the ethos of 'not conflicting with the OP's intent' but if that intent was unclear & there has been no return to clarify, it seems 'better' to fix it than abandon it.
Even if that's not what he meant... 'better' for the site overall than the individual.
Is there a tag for "copy this photo look"?
How should we handle the "what (Instagram) filter is makes this photo" type questions?
What should we do with questions which assume photography is all Photoshop tricks?
& ultimately - Is there any hope for making this site about photography?
