Just near enough, Sam, that takes the pressure off the photographer. Pursuing perfection in the SOOC I think is always at the expense of other things.
It can lead to a lot of time wasting on the photographer's part and the clients, and repeated unnecessary disappointments when it doesn't happen.
A real estate photographer given 45 minutes for each job in the list the boss assigns them in the morning is mad if they don't use flashes, HDR and sky replacement in Photoshop to get through the day.
When the CEO needs his picture taken for LinkedIn, and you want a one hour shoot, and his personal assistant says you've got ten minutes on his way out to his car, you just have to roll with it.
We can be much more anally retentive in our personal projects, IMHO.
