Lartigue Lever for Graflex Super D (~1/50 sec on 1/8" aperture)- Distorted Wheels at Safe Speeds!

<p>Ever since the the Met showed Jacques-Henri Lartigue's private catalog of images in the 60's, people have been in awe of his 1913 image of a speeding car with distorted wheels and swept-back spectators. &nbsp;It's an effect of him panning the camera to follow the car, and the horizontal slit on the focal-plane shutter on his ICA Reflex camera. Recreating this in modern times is a challenge, many cameras with focal plane shutters (35mm and medium format) have vertical slits on their shutters. &nbsp;Graflex SLRs are a natural fit for this with their large horizontal 4x5 focal plane shutters and narrow 1/8" apertures available, but the problem is that that aperture is only available at ~1/500 - 1/800 seconds, which is too fast for a vehicle to travel much distance.</p><p>What I've created is a device that allows use of the narrowest 1/8" slit on a Graflex Super D to be used at much slower speeds (~1/50 second) so the “Lartigue Effect” can be maximized. &nbsp;It has two parts, the “Lartigue Lever” that attaches to the bipost flash sync port, and the “Lartigue Cylinder” that slips over the aperture selector knob. &nbsp;The lever applies extra friction to the cylinder and slows the movement of the aperture curtain of the shutter. &nbsp;It requires no permanent modifications to the camera and takes a mere 5 seconds to slip into place. I provided two lever designs so you can select an amount of friction that's right for your camera.</p><p>&nbsp;</p><p>More on the technicals of the effect are explained in this fantastic LFPF post (and Matlab simulation).</p><p><a href="https://www.largeformatphotography.info/forum/showthread.php?31903-Jacques-Henri-Lartigue-and-his-camera">https://www.largeformatphotography.info/forum/showthread.php?31903-Jacques-Henri-Lartigue-and-his-camera</a></p><p>More on the image and Jacques-Henri Lartigue:</p><p>https://www.metmuseum.org/art/collection/search/283256</p>
