The old Motor Sport car "Leaning Forward" effect

I understand what is going on, but still I love those pictures!

this effect is still visible in current-model high-performance SLRs: you just need faster-moving subjects like propellers to make it visible.

edit: "Hi, Hoffy!"... I ain't stalking you, only noticed whose thread it was after I posted

Howdy Poly. Nice to see you over here.

To be honest, I have never really noticed it with the props. I suppose when ever I have taken aviation pics, I have tried to blur the props, so you can't tell. I also suppose that you would just about need to be face on to get the same effect in that scenario (& of course, we are talking high performance current FILM slr's )

of course we are Have you tried the 28-75/2.8 on your 7000 yet? Is it working as well as expected?

[hoffy]

No, I haven't!! When ever I have had a chance, its been horrible weather!

This is very interesting stuff. I wouldn't mind trying the effect out for myself. Which model Graflex's have the slow moving slit-type shutter? Did they only make them certain years?

Any of the focal plane shutter equipped graphics should do the job.

Thanks, I've been thinking of a 4x5 for handheld stuff for a while, and one that would also add the possibility of this effect would be interesting.

So this would also work (sorta?) on a modern 35mm slr, like a Canon AE-1P? Or would it not? It would depend more on the shutter speed (the width of the focal plane slit)? I sure dont fully understand this. Can you tell? Also, why is the front tire more exaggerated than the rear tire on the race car? Just wondering.

Yes it would work with a 35mm SLR.
There is only one constant and that is that you must use a shutter that exposes the film via a slit/slot/window traveling vertically across the film plane.
Everything else is determined by the relationship between the shutter speed and the speed of the target.
To a degree, the effect comes from slow shutter relative to the target but if you get the shutter speed too slow, all you get is a blurry mess.
You would have to do some experimenting with different shutter speeds to find the sweet spot if you were trying for a deliberate effect.

It was caused by the focal plane shutters in Speed Graphics. Due to the travel of the shutter, the top of the car would get a slightly earlier exposure than the bottom, resulting in the leaning effect.
