It's not just about saving time - it's also about helping you do more with the time that you spend.
Make the most of your time before the session. Using images gets you on the same page quickly and allows more time for exploration and ideas. Session Board keeps the communication flowing by making it easy to keep track of questions, comments and changes.During the session, use a picture of a pose, prop, facial expression, etc. instead of trying to describe it with words.Spend less time after the session when post processing the results by applying your client's visual taste (learned from the initial collaboration).
