I'm at the moment preparing for a joint exhibition. My class lecturer is very much pushing consistency and is suggesting that we keep more than one important element present in each of the ten images. For example he has advised me to maintain a black background, multi-exposure, the same atmosphere and theme throughout the body of work. Yet, when I look at professional photographer's exhibited work I don't see such blatantly obvious and plentiful common attributes , like for example you would rarely see ten images being exhibited with all the same background. I would really like to hear others opinions on this. I'm not against the idea of what he's suggesting, I'm just curious to see if it's a general consensus. Thanks.
