X-ray,
I know some of your award winning photos, and I look at them every now and then in the B&W magazines. I think these are great photos, and would not call them not creative. However, photography has many faces, and it can be artful in many ways.
I love to look at photos that are so breathtaking that they invite you to "walk in". You cannot "wallk in" into an unsharp, tonally ugly and badly cropped photograph. Some other photos I like, convey above all the concept of beauty - like your tulip shot.
I do not think you can convincingly show beauty in a technically poor photograph, although here the sharpness might not be mandatory - many soft focus or pinhole images appear beautiful to my eye.
Then I like photos that convey a mood - these can be of varying degrees of technical perfection, and often they are on purpose technically" imperfect",like Daido Moryiama shots.
Finally, I love shots that convey emotion, that bring vitality, movement, go to the edge of visual perception. These are seldom examples of technical rectitude.
Yet, each of these artful kinds of photography, bear some kind of a technical language which is appropriate, or shall I say, sufficient, to supply a framework for conveying the creative vision of the author.
So, to sum it up, I do not think there is any conflict between the technique and creativity, it is rather that sticking to the same technical canon can bound your creative expression, because it ties you just to a certain way of seeing.
A sharp portrait?
A bench where you would like to rest for a while?
A cactus you would like to caress ?
Or a metro car that you might want to skip, just to stare for a moment?
A direction you might like to find...
A coffe you might like to leave cold on a caffe' table...
A black cat you might want to avoid...
A drink you might want to take with a friend...
A moment of anxiety ?
A reflection on your everyday life...
Or on the life of the other people...
