Sometimes you just take a really bad picture. You review your images and you wonder how that happened. You wonder how you could have got the exposure wrong, how the focus can be so far out – in fact, what exactly are you focussed on? Certainly not the subject of your photograph! So press the ‘X’ key on your keyboard, forget about it – you’ll delete it later, if you ever remember to.
Then one day, maybe weeks later, maybe even years, you do stumble across that thing in your catalogue that disappointed you so. It’s still there, festering in your catalogue. Right, time to take action. Select it and press the delete key. It makes no difference whether you press the delete key hard or soft, but there is something cathartic about giving it a good, firm ‘tap’. Begone!
