Photography Question

How many fps will i require?


Im looking at buying a camera for shooting wakeboard. I would like it to take action sequence shots.

i want to be able to tell whats going on in the sequence of shots. I dont want to get one frame of them taking off, one while they are in the middle of the trick and one of them landing! that will just look lame.

i need to be able to tell what trick they are doing.

My question is, can I get away with 3 fps when the rider might only be in the air for 2 or 3 seconds.
im looking at fuji's s5200 which is in my price range.
p.s.
and im not to worried about the clarity of the photos since I will just be posting them on a website(for the most part)

  previsualize, or watch a video - how many images will be enough to illustrate a 2 second trick? 3-6, then 3fps may be fast enough.

Joe Giacomet   from experience in shooting motox and other extreme sports i'd say 5fps minimum. with 3fps you will miss most of the trick. tbh 5fps only just covers it.

W.    More fps is better. Another VERY important point to consider is: how long before the camera's buffer is empty after a burst so that you can shoot a new burst? With most cameras that can can take an awful long time! Like a couple minutes! Is the s5200 good enough for you in that respect? So test the s5200's mettle!

"im not to worried about the clarity of the photos since I will just be posting them on a website"....?

Huh? Websurfers don't need clear pictures...? Then use a phonecam...

See how many exposures you can make at full speed before the camera stops. It stops because the buffer memory is full. The buffer needs to flush itself to your memory card before the camera can resume capturing again. That takes time!

So it's not only how many fps the cam can do, but how many of those can it do before it stops that is important! That's determined by the size of the camera's on-board buffer memory. Also important is how long it takes to empty a full buffer memory. Because until both sequences have completed your camera is effectively locked. It won't take pictures...

  Steve,
I think the problem starts with your air time estimate. 3 seconds is an awful lot of time in the air, unless the wakeboarder also has a hang glider strapped to his back. I would bet you're really looking at 1 to maybe 2 seconds at the most for a stunt.

Even if you're really good at anticipating the timing of the trick, the best way to catch the action is to start shooting just before the trick, and continue through the trick. This means the buffer problem that was mentioned above comes even more into play.

I think you would be very hard pressed to find a compact digital or point & shoot that could do what you want.

You would probably be better off with a digital video camcorder. This will give you 30 frames per second (or more), and you won't have the buffer problem. You can shoot long clips and capture the frames you want, or even post videos on the website.

You wouldn't be able to print big enlargements - but you didn't say you wanted to.

Life is full of compromises. ;-)

W.    A Fuji s5200 can make movies in the sizes 640 x 480, 320 x 240, at 30 fps with audio, Steve...
