Please think carefully about which photos you show your client. If it’s a bit out of focus, DON’T SHOW IT. ‘Cos if that’s the one they love, and choose for a huge print, then you’re in a world of embarrassment. Embarrassment to have to tell them “Sorry, you can’t have that one big, because I missed the focus” … or embarrassment if you don’t tell them, then they have a huge out-of-focus photo hanging on their wall for all their friends to see.
