Two main differences between the Normal capturing style and the Premium style:
Detail shots
On top of the default photo package, 5 extra close-up detail shots are captured to highlight the architecture and convey the feeling of the home. This extra value helps the agent justify the premium fee and puts more cash in your pocket.
Flambient Capturing
To achieve a more natural look, flambient lighting methods are used. This entails capturing a bracketed set of ambient exposures + a flash bracket to aid in accurate color correction.
You can reference the video below to get an idea of a flambient process that will work well.
