Weathering and Related Reference Pictures

So while on holiday I tend to take a lot of pictures. Amongst these are various reference pictures of weathering - along with anything else which might prove useful.

Last couple of years I have put some of these on Twitter and they proved quite popular.

To make things easier I thought I would do a blog covering it as well.

So here we go, I will group them together but some things are not easy to fit into a single category...I will continue to add to these (I need to find last years pictures for a start).

Rust.
