First mentioned , may even be low quality crappy photos , but if the object intrigues me thats enough to pull my attention , even knowing that photographer sucks in that part of his work. I saw quite a few photos of that type that stayed in my memory.
Second ones , well I will sure look them in some other way , and the composition will be much more important then the object.
Personally I find a great photo , one that has best of those 2 worlds. Some great photographers , were lucky enough find themselves in right position at the right time.
