Using photos on structures

[nachoman]

No matter how small the variation, I think the eye/brain is more aware of texture. Stand as far from a building as you stand in scale feet from a model building with "Photo-bricks", and you will see texture, that you won't see on the model.

our brains also want us to see something there that it expects to be there. In other words, we see a brick pattern, and we expect to see the texture we are accustomed to. If we don't see the texture, it simply looks "wrong". In a modeling sense, sometimes it is better to exaggerate a texture (rivets are a good example) than to do without.
