I have found that I want my body in its most comfortable resting position at the end of the pan. Then twist your body, with your feed stationary, to where you expect the pan to begin, wait for the car to enter the viewfinder and unwind your body while following the car. If you're most comfortable at the start of the pan, you'll tend to lag behind the car.
My technique is to sit/stand facing 35-45-ish degrees to the point where I'll take the shot. My aim goes off target a little as I go over 45-ish degrees, but by then the subject has been snapped. This is the opposite to Bob's, so I'll change it around and see if his way suits me.
I wanted the car to be directly perpendicular to me or with just a little of the front showing, so timing was extremely tight.
Yeah, the amount of missed shots due to timing :-) I'm trying to fill the frame with my subjects now which makes things harder as they're RC powerboats (and fast ones at that) and they skip all over the place with slight changes of speed whenever they catch on a ripple (or 'wave' to these models
). I'm gagging for a large sensor >10 fps camera with no lag in the viewfinder too.
Re shutter speed: 1/200 is fairly conservative. It'll likely give you the blurred background and plenty of keepers but I'd go real s-l-o-w and trade keepers for really
blurred backgrounds - it'll give you fewer keepers but they'll have wow factor. The nature of formula 1 means you'll get plenty of opportunity to take many shots of each car. If it's your first time I'd suggest mixing it up:
- Start out with 1/200 and pixel peep to check you've nailed 'em.
- Once you've nailed a car, reduce shutter speed to see how low you can go.
