Originally shared by Frank Smith On moonlight bay. Fisherman Bay, South Australia, it's a holiday place that I call home. Day 5/7 #challengeonnaturephotography Thank you for inviting me to this challenge Martin Herrick . In turn I would like to invite Thanh Au to participate if he wishes. This challenge originates from Margaret Wong and the only requirements are to post one of your own nature photos each day for 7 days.
