I have recently gotten interested in some photo's that I saw at an art show this weekend. And I'm trying to figure out "how" they did that...It seems pretty straight forward but I'm thinking there is more to it. I found this article on it. The artist that I saw had his photo's labeled. Painting with Light (I have no examples of his work...sorry) but they were beautiful.

It seems to be "motion blur" but in the article they state that the camera is not moving and it is done "in camera". "The ‘blur’ effect is created directly in-camera using a Roundshot panoramic camera that modified the film internally while the body remained motionless."

So how do you capture the horizontal lines without moving the camera (in a digital camera). I also know that you would have to use a tri-pod to achieve this. And unlike the examples in this article. The ones that I saw were very large and "wide".

Corel Painter. Start with a good shot and have at it.

The Roundshot camera consists of a motorized mount and a motorized film spool: the camera rotates one way while the film is spooled off in the opposite direction and in synchronization with the speed of rotation. End result: a long, seamless panoramic film. What this artist is doing is disabling the rotation of the mount, so the film is being spooled past the shutter slit with no corresponding camera rotation to offset it, and extended blur is the result.

You can get a somewhat similar effect by leveling your tripod up precisely and panning the camera during a longish exposure, but it won't be quite the same because HIS work involves a moving film blurring a stationary scene, whilst YOUR result would involve a moving scene and a fixed "film", your sensor.

Excellent explanation, sir.

+1 Thank you Robert. I followed the link but I wasn't sure if he was talking about something else...I'm going to have to try this...I love the effect...I've done the Vertical/Circular/Zoom-In/Out motion blur but I've never thought to try horizontal motion blur....

This one of PennyClick's was a panned long exposure:

.4 secs

did she press the shutter after starting the pan?

I do these without a tripod. I stand with my feet about 3 feet apart and start rotating the upper part of my body back and forth through about 120 degrees. After a few rotations, when I've got a fairly steady movement, I press the shutter release button part way through one of the "rotations".

Some lighting conditions require a neutral density filter to be able to get a long enough exposure without having the sky/other light areas completely blown out.

ETA: When shooting I routinely select my focus point using a separate button, not the shutter release button, so I've taken care of that before I start this process.

Lovely. Thanks for the explanation.

i'll have to try this out. seems like a great way to make great images when the scenery is lacking.

I really wish now that I had gotten the photographer's card...his images were stunning...when I was walking up to the booth I thought...oh what a really nice paintings, smooth, calming, soft colors...then I realized after I walked by that what he had inside the booth/tent was photography...honestly I couldn't tell that it was a photo at first...

Love yours Penny....I'm going to try this very soon...

It's a lot of fun. I heard about it from Alison Shaw 8 or 9 years ago. She is a wonderful photographer who lives on Martha's Vineyard. Alison Shaw's web site

it doesn't seem like the movement is much...am I right Penny?

And good for your abs!

You are correct that there is not that much movement during the exposure. However, I find that I usually want the overall movement to be longer and wider so that the exposure is during the part in the middle when I'm moving at a steady rate. But it's not fixed in stone. Once you've got the general idea you can introduce your own variations.
