Gee, the camel lover jumps on a simple typo. Do you realize how immature this makes you look?

Only an order of magnitude less immature than your fucktard post where you made the error was. Only an order of magnitude less immature than your "camel lover" retarded remark above is.

Get a clue, dipshit.

Modern projectors certainly do show each frame twice, or more rarely, three times. The ones which I run most often, a pair of Kinoton FP-30Ds do it with a single bladed, double speed shutter, but a two-bladed shutter rotating at frame rate is more common in more conventional machines.

Film cameras obviously do use a single blade shutter, and expose each frame only once. In some designs, e.g. Arriflex, the shutter is silvered, and the light reflected from it when it is closed is used to form the image in the reflex viewfinder. That image does flicker at 24 per second, and is most unpleasant to look at. You couldn't run film in a cinema at 24 fps and show each frame only twice. There have been a few specialised systems which run film at a high frame fate, e.g. Showscan at 60 fps, and others at 48 fps which do show each frame only once, but these are very rare. All normal cinema projectors show each frame twice, or three times, to reduce the flicker.

Since sound on film became universal in the cinema, three bladed shutters were more common on 16mm projectors, which were more likely to run silent film than cinema ones. A few could even be switched between two and three blades at the flick of a lever, or automatically, by a centrifugal device, depending on the speed they were running at.

No more so than any other article he writes. Don't respond to the 'jit (I notice people in SED have pretty much stopped).

*FILM* projectors do (all 3x, AFAIK), but notice the way the moron, DimBulb, phrased his post. "Modern", if by that he means the DLP sort, "projectors" do not flash the frame twice. They're more like LCD displays.

Film projectors, yes. DLP, no. You've stepped into DimBulb's trap.

Hardly "modern". ...had to say it before Dimbulb, sorry.

Out of bananas again, my little monkey? Or is it your time of the month?
