Signs
How can i see when it is enough ? How do i know when my model is going to get exhausted. When does she start to be unwilling to pose ?? Well this is indeed a very difficult task. But let a picture tell you:
When such look appears, your model definitely has something in mind. So look out, beware ! Whatever it is, it has nothing to do with your photographic skill or just exactly and you better stop working and should offer a refreshment. Coffee, tea, cookies…. :) or quickly run awayhayhayhhayhahya…. lol
Or you can use this mood for the next storyboard… nice idea ! I like that :)
