can’t say. depends on too many factors, mainly occasion and mood.
not to be generalized, but a fresh impression may be my last weekend trip to amsterdam: i pressed the shutter button a little less than 300 times and imported half of the images. so the other half got eliminated in the first viewing round that happens in the evening on the camera screen. i kept 32 of the photos and show 23 of them on this website. don’t ask me now how many of them i consider good photos (will be a fraction or zero).
fun fact: martin parr told the telegraph in 2011, that the takes tens upon thousands of photographs a year, prints maybe 15,000 of them and is happy if he can consider 10 of them as good ones.
