Tips for riding shots... plz

Action shots? or scenery?

if it's an action shot, set the camera to shutter priority, and set the shutter so that's there's just a hint of motion blur, helps make things look a bit more dramatic. The actual shutter speed will vary of course depending on the speed of the bike.
Try and take shots whilst the rider is doing something interesting, like cranked over on a bend, or when there's visibly a lot of air between the rider and ground.

If you're taking pictures of someone doing a jump on a trail, be careful with your angles. Taking the shot from the wrong angle can make it look like the bike is only a few millimetres from the ground, this is especially true of directly side-on angles.

An interesting shot can be done (much easier if you have a tripod) by looking directly down the trail so the rider is coming straight at you. Set the camera to somewhere between 1/20th or 1/10th shutter speed, and then zoom out WHILST the camera is taking the shot. gives an interesting blur from the central point

If you're in a dark area, use a rear curtain flash so that the rider will be crisply lit.

if the rider is coming past you at speed, try panning the camera to keep the bike nearly central in shot as he/she goes past, this will result in the rider being fairly crisp, whilst the background blurs considerably to give an impression of speed.

And finally, if you want shots to look a little more interesting, try what's become known as the "MBUK" angles - this means, if you're taking a shot of someone riding down a steep trail, try tilting the camera slightly off vertical to slightly exaggerate the steepness of the hill.

Good luck, post the pics when you get back

Went to a motorcycle race meet yesterday, had to adapt techniques quite a bit, as the speeds are completely mental! Got some images up on my Flickr page (link in my sig.)

Well, I used to take my old fuji with me on the bike, but it didn't take very good pictures. I tend to keep Flickr for my best ones.
As soon as my riding buddy recovers from chemo, I'll definitely have a few more MTB shots up there.
