A photography session is not just about the split second in which the camera shutter opens and closes. It's a complete package. Was it straight forward to organise? Did the photographer put you at ease during the photo shoot? What was the follow up communication like? And most importantly, were the end results as good as you were expecting, or better?
Quite simply, if you're not happy, then neither am I. So lets work together to make it a positive experience all round.
