At 1600 ISO, TMY grain is somewhat controllable via exposure. Properly exposed it is very fine grained processed in Xtol. If you WANT some grain for artsy purposes just under-expose that shot.
The two examples below are frames #23 & #24 from the same roll of bulk load TMY @ 1600 processed in Xtol as described in my previous post. #23 is under by a couple of stops. It is not manipulated post-process except crop, levels & USM (no burn/dodge or vignetting).
Imitation cameras come with big egos, real cameras do not include accessories.
