One of my current goals is to put together a series of shots, a portfolio if you will. This requires some forethought as I am shooting and also in post processing. It's like moving from one cool note to a phrase, verse or eventually a song. It varies but a series would be from 7-15 shots. It could even have a beginning and end to the sequence.
A series should hold together visually, tell a story and ultimately evoke an emotional response. I am just starting on this but it is the next step for my photography. Here is my San Jose Obon, 2015 series:
Pro Tip: These projects sometimes come together better looking backwards, even after the photos sit for awhile. Best to shoot a lot, then in the editing process get a feel for the story.
