I think there is a line that links Absolute Technical Mastery at one end with Significant Creative Achievement at the other. People move about on that line at various stages of their photography, according to the efforts they put into improving their 'vision and creativity' or learning 'technical mastery' of the craft.
Generally, when we start out, technical mastery and the creative aspects seldom come together and meet in the same picture.
But as we apply the effort and learn, the two come together more often.
The thing is however, people give different priorities to what they see as advancing their photography. Some might use whatever film is in the camera, flick it onto Auto and point and shoot, with the creativity being the beginning and end of what is important to them, as long as it results in something in a print! Others go through film/developer combinations until they are blue, refining their technical knowledge until they can predict the proportion that each zone will appear in the final print.
If you are truly an exceptional photographer, you will achieve both in the final image. Using landscape photographers as examples: Ansel Adams and his ilk, and I would suggest Bruce Barbour as a modern day example.
Fortunately, photography is now considered enough of an 'Art form' that you do not have to have a perfect balance of both. But (and this is just in my opinion), the more consistently you are able to support significant creativity in your photography with disciplined, accurate techniques, the better a photographer you should be regarded.
Many have already said it; .... some get lost in the tech aspects, and their creativity suffers through lack of attention. I have seen outstanding ULF prints, the result of decades of dedication and refinement that leave me cold with boredom. Likewise, the other way. Plastic camera shots that are unrecognisable, but should be appreciated for the wonderful pure creativity involved.
We all should have our individual views about what is most important for our own images.
Personally, for the record I apply creativity to my photography with a passion (and normally it is excruciating and rarely satisfied) and I try to support that with technical skills necessary to achieve the result I want. I don't pursue technical accomplishment for its own sake, seeking subjects to display the technical merits of the image.
However, who is to say any one way is right or wrong? In addition, who is in a position to criticise anyone who has applied themselves with passion, vigour and dedication to their personal goals of photography (just my 2 c).
