Of course, that's why you'd choose a big name photographer. If the idea is weak and you are looking for someone with the skill to lift it executionally. Ditto commercials directors and anyone who actually does the final job. But it remains commercial, even if they choose to re-badge it art afterwards. Actually Campaign mag did start a competition for advertising photography as art and I thought it was a great idea. I was a judge and you definitely could appraise it as art. Sadly only lasted a couple of years, but it did quickly get into a rut with social causes stuff always getting marked up by a couple of the judges.
