Best Buddies

Renfrebar has to return to Innsbruck tomorrow, so we used the opportunity for a photo shooting together with Omo.
These two are best buddies!
R. had also the idea of a western themed photo. (extras)
I would like it in sepia, but Photoshop has other ideas (to drive me crazy and refuse the cooperation) Perhaps I'll change or add it later...
Okay I found a tutorial for dummies and now I could change it into sepia. It's simple - if you know, how ( and if you use another way than the official PS description offers)
