I’d love to claim that images spring forth from my camera fully-formed & beautiful, surpassing any need for downstream correction. Alas, no. Even my best shots are improved with a little tweaking. In this post I explain how I crunch a raw capture to produce a field-guide type photograph. For brevity I will leave aside [...]
