Tips for motorsport photographer

[Pizzamannen]

Hey!

So I've asked to work free as a photographer on 2 events at Red bull ring in Austria. Both parties were happy with my work and I've been invited to join the racing series for 2016 as a media photographer if I want.

Do you have any tips?
I never went to photography school. I know you can just shoot away thousands of photos. But someone has to flick thru them. Do you do your editing yourself? Or do you leave your sd card to media responsible at the event and they check thru your pictures?

I mainly ask the events if I could photograph for free I give them all my photos for them to be able to use for there website / promotion whatever.
For 2 days i took like 3000 photos and I worked hard on going thru the photos my self checking cropping and tones and so on. At the end I ended up with 1259 photos which were sharp and looked good.

But it took me one and a half days. So the guy in charge got the pictures a bit late. So do you pick a lot less? Like the 20 best photos and send it via email quick ?

Just want to hear some ideas .

Thanks!
