When I first got my DSLR, I was shooting literally thousands of shots a week. Within the first 4 months I had shot 30,000+
Most were rubbish. And every shot had exposure bracketing (and sometimes all exposures were wrong). I doubt even 5% were keepers.
Then after constantly running out of storage space and never having time to look through them all, I decided to be a lot more selective.
Now I might drive around for a few hours looking for something good to photograph, and I often come home with just one shot - but a good one!
I'd say my success rate now is 50% on a bad day and 95% when I concentrate.
To be fair though, I couldn't have done this at the start. I needed to take those tens of thousands of crap shots before I learned to recognise what's good and what isn't.
