Beach Half Sessions - Sunny day time slots

Below is an example of 3 family half sessions that I shot back to back on a very sunny evening. Each session was about 25 minutes long. We start no sooner than 90 minutes before sunset, but preferably closer to 75 minutes (time slot 1), then 45- 60 minutes before sunset (time slot 2), and finally 20-30 minutes before sunset (time slot 3).
