G+ has given me the opportunity to study the images of amazing photographers and seek their council. And each one of them has responded with insight, compassion and encouragement far beyond my expectations.
If you are new to G+, do not be concerned, there are many talented photographers more than willing to share their knowledge with you. Study them and interact with them, you will become a better photographer for it.
As you develop your skills, which can only come from continual practice and experimentation, post your work on G+ and participate in some of the many wonderful Daily Themes and Communities.
Learn from the feedback you get and give kind and gentle feedback to others.
Above all, have fun, share your images and interact with others. And practice, practice, practice.
Enjoy the journey.
