General questions
Why are there so many event photos that nobody looks at?
The short answer
Because we shoot so we will not miss out, not so we can come back, which leaves a huge pile that is hard to scroll through. The answer is not fewer photos, but a way to bring each person their own moments.
At most events, hundreds of photos pile up between the photographer, the guests, and the shared groups. The bigger the pile, the less likely anyone is to go back to it, because you have to dig through a lot to find a little.
When every guest gets easy access to the photos that are relevant to them, instead of a sea of everyone's photos, the photos actually get seen. It shifts the weight from quantity to relevance.
