basically, creating movement in the background / keeping the moving subject matter crisp when it's heading straight toward you, so standard panning is not an option.

With a zoom lens, as the car come towards you zoom in.
I hope that makes sense.

It does indeed, that was the only explanation I'd come up with, I guess you chose a focal point, lock it there, then go out of it, track car with zoom and fire off at the preselected focal point?

Yes now get down to the hard shoulder of the motorway and give it a try.

I envisage much wasted shutter clicks in the upcoming days!

Think I'll try the local roads first, practice with something moving a weenie bit slower. Maybe get the wife on my bicycle hehe

I'd say that was Photoshop.
If as it says, was taken during a Grand Prix, then I'm sure it wasnt taken from another moving car or rig.
I would have thought some selective blurring using gaussian and speed blur using masks would give the desired effect.

it is similar to that Nick, but I'm assured this is the chaps signature style of photography, and not created with photoshop (photo taken in 1971). Not knowing personally and knowing the fan I was discussing it with is extremely well versed on the chaps photography (plus it not being impossible LOL) I'd like to believe him!

Depending on your camera you can do it with constant AF too, unless it was just luck thats made that work for me - I haven't got it right very often!

Zooming in to follow the car here, not as good as the example above though:

it's a nice shot GB, but the exact opposite of what I want to achieve hehe - I'm looking for that ragged streaked pic effect. I've achieved it before on the one below side panning, but not fore to aft.

I put the wrong image up at first! That one better? The bushes etc around the edge are blurred while the car is (relatively) sharp. What you're wanting is the same basic effect with a slower shutter and more colourful background no?

That photo is zooming in as the car goes away, you'd be zooming out to keep it sharp as it comes towards you.

I think zooming and motion blur are getting mixed up.

There may be a way in PS to achieve the effect, but the original way is to zoom (ie change focal length) while the shutter is open. The blur is going in all directions - impossible with just panning.

I'll just leave this here



Handheld 1 sec @ f/11, zoom whilst shutter depressed. Crop & levels otherwise no PP

I can see it now. If it is zoom blur with the lens (which I think it is) he must have cropped the image to get it off centre smile

Nope, it just depends how you move the camera as you zoom. Just find the centre point and let your eyes work it out.

If memory serves around the time the original was taken was shortly after the point at which quality zoom lenses were just becoming available so there was much experimentation going on and many examples like that were shot at the time.

Another thing to remember is that, to some extent, if you are close to the subject ven just a slight pan can leave you with a small section of the image sharp and the rest, front and back of a car for example, out of focus simply because they are in different planes and so move at different speeds relative to the point you are 'focused' on. Add in the shutter lag effect and you get some of the effects in the shot. However the background zoom effect will be all zoom. I wonder if it was a twist zoom or a push/pull design? Either way well executed and would likely require some considerable practice (or luck) to achieve consistently if hand held.

That said, somewhere at the back of my mind is a recollection of reading about a zoom that operated on a squeeze trigger principle. I would guess that would have been good for Cevert type shot. Hmm, will search later to see if I can dig anything up.

Looks like a zoom effect to me - similar to the Dolly Zoom in cinematography, but with a stationary camera and moving subject.

Right, a little surfing suggests that the early zooms, from companies like Voigtlander started to appear in the late 1950s and look like they were push/pull devices that, in theory at least, should be an easier action for that type of shot. Rotating to zoom was never easy - I tried it.

The lens I was thinking of (Novoflex) with a trigger zoom was not in fact a zoom as far as I can tell - it used a trigger like system for follow focus on a long telephoto. Whether anyone produced a similar system to operate a push/pull zoom I don't know. I guess it would be possible to make one - perhaps as a self developed aid. I suppose you could also make one for a rotating zoom control.

The Schlegelmilch archives may be able to provide the information about how the shot was created.

I can confirm this isn't easy at all :P

I've decided to scale down for practice with a remote control car hehe

The Young Simpo used a 70-210mm f3.5 Vivitar Series One to capture his first 'zoom while the shutter's open' shots at Nottingham's Goose Fair in 1984. And yes, it was a 'one-touch' zoom - no AF to worry about you see.

And no bloody monitor in those days either! But we wuz happy....
