W/NW: Your Favourite Slow Shutter Shot

[teo]

SLR? Why are the wheels round given it's a focal-plane shutter

eee, uhmmm. Sorry for my ignorance, but I don't understand why they souldn't be...

Focal plane shutters distort at slow speeds, circles go a bit oval or egg shaped that one looked slow enough the see the effect but doesn’t show it, nice shot by the way

Thanks
It was first panning of my life too bad for the harsh OOF, it was a f22...

If it's an SLR with a horizontally-travelling shutter?

If it's an SLR with a horizontally-travelling shutter?

No, I think the effect we're thinking of comes from rather slow-moving large vertical-travel shutters such as Graflexes etc. As the FP slit moves downward, the (inverted image of) the bottom of a horizontally moving object is exposed first, and last for the top. And in the lapse of time for the shutter to travel, the object has moved relative to the film, and appears slanted toward the direction of its movement.

I think a slow-moving horizontal shutter would slightly compress (horizontally) an object moving opposite to the shutter movement and stretch one moving the same direction.

Yes, I used a Minolta X-700, with horizontally-traveling shutter.
(I'm afraid we're hijacking the thread?)

This was actually shot with a slow shutter time (1/4 or 1/8 sec), wide open:

Leica M6 + CV 35mm Ultron f/1.7 / Kodak Ektachrome 100

So there are some exceptions to the "blur" rule for "slow" shutter speeds.

 

[Dougg]

You're right, teo, we're probably hijacking the thread; just one more observation... That focal plane shutter curtains move the same velocity for each shutter speed. They don't move more slowly for slow speeds; they just remain open longer. For fast speeds, faster than the X-sync speed, the second curtain starts to close before the first curtain has completed its travel, and this accentuates as the speeds increase, until at high speeds there's just a narrow slit between the first and second curtains as they traverse the distance, still taking the full X-sync time to complete the journey and expose the whole frame.

A trio of examples:

- First image: Amtrak Metroliner (one of the real ones), Elizabeth, N.J., 1976. Tech info: Canon EF, FD 24mm f/2.8, 4x ND filter, Kodak EPR, approx. 1/15 sec. (amazed I remember this much...and how about all these trains in this thread!?)

- Second image: Chelsea, NYC, 1996. Tech info: Konica Hexar autofocus, Kodak TXP, somewhere between 1/30 and 1/60 sec.

- Third image: wedding, Brooklyn, NY, November 2005. Tech info: Konica Hexar RF, M-Hex 28mm f/2.8, Ilford XP2, slow-sync flash.

I’ve seen it from both an M3 and OM1, I assumed it was common but I can’t actually find any examples, perhaps my imagination

one from the other week

 

[kestas]

1 Rf + 1 Slr

1 Rf + 1 Slr

my 5 cents.
first one made with oly xa (~2-4 sec), second one with pentax slr and 50/1.4 wide open (~1/4-1/8 sec)

 

[Cooki]

The bar shot is with the XA at f16 and about 10 seconds , and the pool shot is 1/40 at f3.5 with the 35RC. I use the pool table as a busness card image.

BessaR+Nok50+Ilford HP5 shot@1/30 or 1/15 (can't remember...)

 

[rolleistef]

not shot many slow speed photographs, but here's one I like very much. In Geneva last august, around 11pm, HP5, Rolleiflex (sorry no RF, don't ban me!), f:3.5, 1/8, handheld.
Processed with rodinal.

 

[jamesj]

here is one from me...

 

[pvdhaar]

Here's my personal favorite where photography and quantum physics meet.. Broadly speaking, the Heisenberg uncertainty principle states that you can either capture motion or position, but not both at the same time.. We now know Heisenberg had it completely wrong; I'm located exactly in my car, and the speedo shows exactly 25kmh.. Take that, Werner!

Oh, and image details: Bessa-T+CV25/4, 1second exposure on Fuji Xtra-400..
