It's not a new phenomenon for history makers, but this Associated Press article points out the value of capturing moments in average days with really good photography for the rest of us.
Quantity isn't the issue. The pile of negatives and prints in your drawer that quit accumulating somewhere in the 90's, and moved to digital storage generated by your new digital camera has multiplied exponentially due to ease of capture. Now your photos are on your smartphone, growing by topic, subject and time. There's casual capture of, well, everything via Narrative Clip, Google Glass and GoPro. But casual isn't iconic, access isn't everything and many image aren't worthy of your family's precious archives.
Seeing the light, composing with skill, relating to the subject and generating a technically superior image brings worlds into view. Day-in-the-life photography sessions take a little time and expense, but there's a priceless quality in daily interactions with our loved ones that makes each moment worth remembering beautifully.
Keep collecting and curating images with all your tools, take the time to properly back them up, store them and even print them for display. But think about bringing in someone who can start building a library of powerful, emotional, high quality images for your walls, for sharing, for your history.
