Toni,
"The dilema starts because I have notice that to the few people that I have sowed it, the response is plain blankness. No emotions."
That's their problem, not yours. I have argued repeatedly that human photography and still life are 'creative' where I find landscape not to be. I don't wish now to offend anyone any more than I did on postulating this belief the first time; it's only how it affects me, so please don't anyone feel obliged to tell me how mistaken I am - you could be absolutely right, and I just can't see it.
That Coke thing isn't actually any more demanding of me than anything else; it just illustrates my reactions to an object when I place it in a given set. And there's the thing: I have always, genuinely, felt my landscapes to fail because I can only envisage landscape as set for something else. And an empty Coke bottle comes free!
I like your still life work and you have a good grasp of what your tools can do for you. Still life offers a huge scope for lighting skills to shine; all of my stuff is available light of one sort or another, even if a table lamp! I have no studios anymore - I just do what I can where I find it. That is the single capability that the D700 has given me that I never enjoyed before: I hardly ever find myself without enough light to shoot. That's worth a lot!
Regarding Eric's comment about passing an opinion - you may have missed his meaning, but he's right; this box is for everything except opinion in the sense of 'critique' of another photographer's work... You can like it or you can hate it and say so, but you mustn't tell him how to alter it for what you might think is the better! The other boxes invite that!
