I have a little rule I like to keep to. As time goes on, and I occasionally break that rule, I regret it more each time I do. To make it easier for others to understand this rule I'm writing it down.
The rule: One shoot per day. Not two. This goes for me AND the model.
It is a fact that each person has their own energy stock pile between sleep cycles. Most have more energy than me. Another fact. And I'm not talking about just physical energy. Actually, more important is the creative energy...this is critical for any artistic shoot.
Anyone who has done a professional full blown photoshoot knows that several hours posing, creating, and shooting, creates a special kind of exhaustion. You know you haven't done that much physically so it seems strange. It's the mind that reaches exhaustion in this case and it's because everyone is searching for that creation that the particular collaboration might bring to light.
Creativity, in its nature, takes as much energy as a full day of physical exersize.
This is the basis for my 'rule' of doing only one shoot a day. And, insisting that the model or models I work with do the same. I don't think someone trying to fit two, and even three, shoots in a day, are going to have the creative juices left in the later shoots. Or they will hold back their energy knowing they have other shoots coming up and that's robbing each project of your full attention and energy.
To make the point of how important I feel about this, I won't do a shoot with someone, even it it's their first one for the day. Two reasons. As I already mentioned, some energy is held back by the model for their long day. And, we are robbing the second photographer of the full potential of the model.
So, if you plan a shoot with me, I want your full attention and energy. Don't book another shoot on the same day as ours. Just don't.
