I blew it. I tried and failed. Taken on an ipad camera from my car. She was pretty though. Any tips on candids? She's in the black shirt standing up.

You have to get WAAAAAAY closer to get good candids. At least you tried

If you're not close enough to get the adrenaline rush of danger, you're not close enough.

That situation looks too tough to get a candid. It's easier the more public place you are in. Stores for example no one bats an eye since people are expected to come and go due to shopping. Only crowded public places work like parks or plazas. The goal is to blend in with the general crowed around you nice first attempt though i onow I could not have done better in that circumstance
