The OC mentioned "static lighting". If they meant static, while the platform was spinning, then the lighting would be inconsistent, because the object would change lighting with each photo. You would have to fix the lighting to the platform to spin with the object, while taking the pictures to get consistent lighting.
I think you just nailed why I have been having a hard time with my photo set. It's the lighting. Well crap, because I don't have access to the statue or studio again. Thanks for the tip.
