Rock - Photogrammetry based Environment Texture

Saying that all rocks are the same is like saying all people are the same :). Each is different and interesting on it's own unique way.. but sometimes.. it is just not ;). Capturing that surface I was sure I am going to get very good and useful generic rock texture in result.
Apparently it is not as it is a 'snail nightmare'. Shooting from distance I didn't realize that almost every gap and crack is filled with snails. It was just everywhere :(. Spent hours trying to removed some in painter .. but it was hard to make without noticeable lose on texture quality.
Fortunately captured surface was quite huge.. and most of them colored to grey look like pebbles .. don't they? ;P
Anyway, to capture that surface I took 16 shots which I used to generate 13.5mln poly mesh.
Manual tiling and snail removal done in Painter.
I also introduced Photoshop as additional but optional tool in my worflow as it is still very useful and still powerful tool.
