I like candids and street shots. I've not been doing it that long, and still have a long way to go. Don't think I'll ever reach ABERS' level, but I'm trying.
My main handicap is, that I can only see things that are right in front of my eyes; anything in the distance is lost to me, so I miss a lot of opportunites.
I often spot someone/something when I am too close, have to saunter past innocently, turn round, amble past again and have a go. Sometimes the situation/person is still 'in situ,' sometimes it's gone.
I haven't used a long lens very often, normally shoot people 'right in their face.' I have also practiced 'shooting from the hip,' which gives you a chance to get really close. I have also, on occasion, switched to 'electronic shutter' (I think that's what it's called) which eliminates the shutter sound. (Mine is rather loud.)
I sometimes show the shot and offer to email the file. I have asked permission, especially when shooting children (fathers are 'easier to handle' than mothers. The fact that I am a female 'of a certain age,' and a mother myself - I often mention that - may give me an advantage over men.)
On occasion I have asked people if I could photograph them, but then they immediately 'pose,' which I hate. So I ask them to continue what they were doing and I follow them.
Most of the time I simply shoot, and hope for the best.
