That is a very interesting distinction. Perhaps you have explained it elsewhere and I missed it, so would you please elaborate? Is this in the same vein that one could say the negative to be different from the final print?
it's true that the negative is different from the final print (just as the map is not the territory and the recipe is not the meal -- who wants to eat a recipe, blech! Tastes all papery!) but I was getting at something different there.
What I meant is that the technical quality of the image is often
not the thing that people value most in a photo, and in many cases there is often a tradeoff between getting maximum technical quality and getting an image with greater subjective appeal.
Here is an absurdly exaggerated example to make my point clear: I'm attending tonight's football game, and it's a critical moment -- what happens next could be the winning play that decides the championship. Naturally, since the moment is so important, I want to make the highest-quality picture possible.
So as the players line up, I get out my 8x10-inch view camera and mount it on a very sturdy tripod. I carefully adjust the back movements to get the correct perspective of the goal, and the front movements to maximize sharpness according to the Scheimpflug effect. I load a sheet of very slow, fine-grained film and stop down the aperture to its optimum setting, then use my spot meter to measure the important tones of the scene and "place" them on the correct zones of the Zone System according to my pre-visualization of the final image. I carefully attach a cable release to avoid camera shake during the two-minute exposure that will be required.
At this point I notice that the game is over and everyone has gone home.
If I press the cable release now, I undoubtedly will get a very high-quality
image. But the guy who had been standing next to me -- the one hand-holding the little camera with the fast film and long lens -- had gotten a better
picture of the game-winning play.
The reason is that he had chosen the equipment appropriate to the situation, and I hadn't.
As I said, I deliberately chose an exaggerated situation here, but photography is full of situations in which you have to make a tradeoff between approaches that will yield a sharper, finer-grained image, and approaches that will yield a picture with more interest or emotional appeal.
That's what I meant by the difference between
image quality and
picture quality. A picture is a
depiction, and to make a good one you have to give some thought to what you want to depict.
FWIW...
