Actually, I think its difficult - if not impossible - to separate the two.
You may have an artistic vision but its impossible to achieve your desired results without the technical knowledge of light, f-stops, shutter speeds, composition and ISO. Of course its possible to take a good picture without the aforementioned technical knowledge buts its more by accident than intent and difficult if not impossible to duplicate.
You may have complete mastery of light, f-stops, ISO, composition and shutter speed but without artistic vision they are useless. Its akin to reading the Driver's Manual required to obtain a driver's license but never taking the test.
Of course, using the phrase "artistic vision" opens up a very large debate as to how the phrase is to be defined. I'm not convinced that it can be defined. Since every individual sees a scene differently there are, likely, as many definitions as there are people. Show Monet's "Water Lillies" to a dozen people and you'll likely get a dozen different interpretations/responses. The same could be said for an Ansel Adams print or a Jerry Uelsmann print or a Cezanne painting.
In closing, I believe its necessary to ignore the distinctions between technical expertise and artistic vision. Its the blending of the two that is required to make a truly memorable photograph. One complements and enhances the other. We may enjoy a breakfast of ham and eggs but we seldom debate whether the eggs compliment the ham or the ham compliments the eggs. Nor do we consider if the orange juice compliments the ham and eggs or vice-versa.
