Part of modelling for me is therapy it helps both my bipolar and my autistic sides. Currently its working two ways, building helps me feel in control* in an out of control world so helping to de-stress. The second way? Just because photo's exist of say a particular Tiger tank doesn't mean the camouflage is easy to deduce from it.
So which is right and what's this possibly got to do with therapy? Well I'll give my best answer for the first part, honestly we weren't there and with the quality of the photo's available we can't know for sure which if any options are right. Lighting, shading, the effect of zimmerit etc all make it very difficult to do more than guess. So the second part how can this be related to therapy? It teaches that sometimes with as much control as one has over modelling we have to surrender our rigidity and admit there are things we can't control but can still be enjoyed.
*Maybe gives structure and order would be better words than control.
