John Huft wrote "...We used to get effects like this with moving objects and the moving
shutter on film cameras. The shutter was basically a slot that moved
sideways across the field, often resulting in curved prop blades,
etc.
How does the shutter work in your digital camera (danger, ignorance
warning)?..."
According to the manual, the camera--Panasonic
DMC-FZ30--has an electronic & mechanical shutter, whatever that means.
Aiming a light into the Leica lens when snapping the picture reveals a shrinking
iris ring, but I'm unable to see whether the shutter itself is "leaf" or
"curtain" type.
The image in question was shot at 1/320th second,
at f8, as I recall.
I've attached 3 pics of a friend's KIS Cruiser's MT
prop on its maiden flight taken this month, which illustrate this camera's
ability to capture moving objects. You can judge for yourself about the
"curvature effect". In this case I think the curves reflect the scimitar shape
of the prop. Pic 1 - still prop; Pic2 - 1000 rpm; Pic 3 - 2300+
rpm.
Regarding the original image, perhaps my monitor
isn't as sensitive as some to varying shades of blue.
