"Kill your darlings, kill your darlings, even when it breaks your egocentric little scribbler’s heart, kill your darlings” - Stephen King
As photographers, we need to know if our images make us feel the way we feel because of their composition, light, subject, atmosphere... or if it's our memories of making them that are responsible instead. Because if it's the latter, if it's the context only us have as the makers, as the ones who were there, then no one else is going to feel the same way towards those images.
