Is it possible you can take a photo of me doing the jump with background in a blur???

I agree, a little more info on what you're planning to do would be welcome You can pre-focus (manually, set a shutter speed fast enough to stop the action and use an aperture (in combination with a good focal length) for having a nice background blur ( so tripod is a must). Wireless shooting be best and use continous mode ! Under certain circumstances you might need to use flash too ( that would'nt change any of the above mentioned).

Just open up the aperture as much as possible !
If you want a motion blur then follow the subject
doing his jump with not too much shutter speed !

In order to capture a shallow depth of field (small area in focus), it's best to use a lens that can obtain an aperture between f/1.4 to f/2.8. Lower aperture f-numbers allow you to isolate subjects against buttery smooth backgrounds.

Without knowing which lenses you own, I'm assuming you have the 18-55mm kit lens. This lens can only go down to f/3.5 when shooting towards the wide-end of the lens (18mm) and only f/5.6 when shooting towards the long-end (55mm).

Since you can't get down to an optimal aperture f-number, you're going to have a tough time getting the blurred background effect that you're after. One way you can do this with your kit lens is to zoom to 55mm and create some space between you, your subject and the background. Shoot in Aperture priority (A on the mode dial) and select the lowest available f-number, which would be f/5.6 when shooting at 55mm.

This "trick" isn't always possible, especially when shooting in tight spaces when there isn't enough room. My advice is to start saving up for a 35mm f/1.8G or a 50mm f/1.8G lens. These lenses will allow you to capture sharp subjects against silky smooth backgrounds in a variety of shooting situations (daylight and low-light).

As for settings, you would shoot in Aperture priority and select the lowest available f-number...which in this case would be f/1.8. Hope that helps and happy shooting! :)

you may have to shoot in manual an set the shutter speed fast enough in order to keep from blurring you're self. :) :)

are you using time release or remote trigger?

That's how I read into it too...subject frozen, motion blur on the background.

...but this is the Uglyhedghog, not the Psychic Network.

Hard to explain, like jump up and down ( jump rope)

Do you want the subject frozen and the background motion-blurred?

Blur can also be caused by being out of focus as well.

I would need a very long lens to do it from here. I can't even get my head around the logistics required. ;-)

But if someone closer was there, yes they could do that.
There are several ways it can be done.
If I was going to do it, first off, I would try quite close with a 24mm lens, pan up and down with you, and take the shot on about 1/8th - 1/15th sec as you were falling back down.
The hair suspended out would help signify the falling/jumping movement.
I would have a busy, messy background of semi uniform colour(forest of naked tree branches) so that there was a background with detail to blur but not overpower.
Probably also use F/8 to F/22 to accentuate the blur instead of a wider aperture which would soften the background.
From there I would take trial and error.

EDIT - I was assuming motion blur of the background was required but now am not so sure that is what was meant.

A (Canon) 50mm @ f/1.8 will keep you in focus with a blur background, try different shutter speeds to control blur of your main subject..

it depends what type of blur you want motion blur or depth of field blur. as coyote said. sounds to me like you want motion blur.

For an 'action' shot of you jumping, you will need to use a slower shutter speed and "pan" the camera to get you as sharp as possible while blurring the background in a way that shows you are 'in motion'.

If you are relatively slow and stationary while jumping, such as just jumping up and down, open the lens as wide as possible and keep as much distance as possible between you and the background.

A 400 mm lens, close focus, shoot wide open will totally bokeh out the background. You will not be able to see any background detail. It will be a smooth blend of background colors and lights. You may have to jack up the ISO so you can raise the shutter to freeze your "jump"

270 mm, 1/8th second at F5.3 produced this bokeh
