Than the above is the fault of the photographer, well at least of a pro photographer.
For such shoots I will want to reccee the location first, I can't just take the client's word for it.
How will the "ambient light coming from all places (like large windows, no blinds, etc)" affect the shadow? since no blinds, what is outside the window (another ugly tower block?)? Areas which do not have window, what is the light/shadow like? How do I control the ambient lights to "show off" the room?
Since the place has been luxuriously designed and decorated, how will the decoration affect the overall image? will too many of the decoration become a distraction? How can I show the lighting effect or highlight the arty deco lights with all the unblock window? Would a night shoot be necessary?
A professional photographer should not just listen to the client but do their own assessment and offer their professional opinion so that the client knows what to expect from the shoot/photographer.
I agreed that everyone needs to start somewhere, but everyone also needs to know where they stand, are they at a position to do a proper job even at the most basic level? Do they know what is required and expected before the shoot, during the shoot and after the shoot?
