Inspiration comes both from within and everywhere. It will just happen. Just be ready and open to everything and inspiration will bite at any particular moment. It's magical really. There are moments like these all around us and we experience it daily in our lives. Whether I choose to capture a particular moment really depends on whether it inspires me or not. I will a make decision as to whether that moment (however significant it may be or not) has an emotional connection or story I can relate to or aspire to.
Then right there, I will capture it.
