I think in all forms of creative works, there is always an inner desire to present you creation to an audience or spectator whoever that may be.
I believe that is almost no one who takes a photo entirely for oneself. There is always a desire to show your photo to someone. It will be even better, if that person can relate to or appreciate the photo you have taken.
If you are one that take photos entirely for personal viewing and totally have no desire to show it to anyone else and do not have the desire for others to appreciate your work, I would be very interested to know your views.
