A camera makes you slower on purpose
Software rewards removing steps. Photography, at least the kind I like, rewards adding one: the pause before the frame. I did not expect the hobby to teach me anything about the work, and then it taught me the only thing I keep relearning.
A portrait is negotiated, not captured. You are asking someone to be still and be seen at the same time, which is a strange thing to ask, and it takes longer than the exposure.
I have started treating design reviews the same way. Nothing gets faster by skipping the part where you look.
