In this digital age we all shoot too many shots (some of us in the hope that one of them will be good). My approach is to take my time in how I frame and compose the image (when possible) but also to get it as close to perfect as the situation allows. I'm not being conceated or big headed, but having trained on film where you did not have the luxury of post processing, you got you technical's correct (especially on transparency [slide film]) so whatever you were shooting you planned in advance and took your time to get your work right. Also you had a limit of between 12 and 36 frames on your roll of film and film and processing cost money so every time you pressed the shutter there was a cost and this cost sharpened our attention because money was not in great supply. Consider this if every time you press the shutter it costs you 50 cent (45 p) you would take less exposures but the chances are that they would be of better quality because there was a price to pay. Or if you don't think the money side important set yourself a target that you only have a certain number of frames available to photograph what you want (as with film) and watch how this concentrates your approach. To finish Except for Digital we could all be better photographers! wrong, because of digital too many people think that they are photographers and have not recognized that they are taking thousands of snaps, the majority of which will never see the light of day.
