On a recent holiday to the Cotswolds, we happened upon a small weaving factory/shop, part of which contained a collection of old equipment and weaving objects. A few old photographs in B&W gave me the idea of sepia toning my images.
I don't like the sepia toning much, but your processing is not just simple "sepia" effect and it seems work well with these photos. I also like the second one best but the third one is great too! I'm curious how would they look in B&W?
