Disagree seen plenty of photos with great lighting on what is a rather uninteresting subject and it still.remains uninteresting
And conversely I've seen countless images of subject that should be interesting, but poor composition or lighting leave them look dull and mundane. Subject is important, yes, but other factors carry a lot of weight.
That is a very thought-provoking question Sara. This thread has meandered a bit and although skirted around the subject, have not clearly reached a conclusion whether craft is art. From my perspective, art is anything that involves an element of creativeness. In the case you have put forward for instance, the subject is there so already created in that sense. Yours is a craft that enables that creation to be presented in a pleasing and worthwhile way - a skill, a very laudable skill and one that any sensible person would crave for but nevertheless it is craft, not creative art. Just my view. I suppose the follow-on question now is at what point does craft become an art ... if it does at all ?!?!
I don't think your definition of art as "anything that involves an element of creativeness" holds true. It's much more complicated than that. Perhaps a better question to ask is, "why does it need to?"
Take a recent example of astrophotography, the recent flyby and subsequent images of the planet (they made it a planet again right?), Pluto. Now that was no doubt billions of dollars worth of research and equipment, not including all the accumulative impacts of all previous research, development and creativity that managed to make this project possible. All the highly skilled people involved, who have been working on this event for their entire career in some cases, all working as a team, across corporations and governments to get that camera into space and send it out to the farthest edge of our solar system. And then, get the images taken back to earth.
Now the images itself is pretty much the same as, say something I might take with my biggest lens of the moon. I probably have more creative control over lighting, as long as I time it right (the NASA scientists could probably do the same if they had factored it into their calculations, but it may have delayed the project by several decades). They didn't want to be artistic, nor did they need to in order to inspire people across the world. Art isn't the only thing that can inspire. Astrophotography, along with many of types of photography (or creativity for that matter) can stand up perfectly well on its own merits without the need to start classifying it as art.
