Sepia adds a nice warm 'old' feeling to the subject. I'd pick your favorite also.
very nice. i like the 2nd version of each barn.
I'm not a big fan of sepia, so I like the other two best, especially the first b/w one. It has a brightness that's appealing.
Funnily enough I like the sepia for the old barn, it 'fits' but am normally a bigger fan of b&w.
Funny thing about barns in black and white...it's a whole different ball game. Great shots.
