Minimum > Maximum ???

[SamBones]

The other day I was in a computer store drooling over the high end digital cameras. I was reading the specs on a little data card for one and came across this...
[ul][li]Shutter speed: Minimum 30 seconds, Maximum 1/8000 second
[/li][/ul]
I stood there for a minute staring at it. I realize if we're talking about the "speed" of the shutter, that a longer time is a slower speed, but does this sound backward to anyone else?

It sounds a little backwards, but I understand it.
The slowest speed is 30 seconds, and the fastest is 1/8000.
I'm drooling too.

Max speed would be smaller number...maybe? I can be wrong

 

[Stella740pl]

Well, if it's a speed, it shouldn't be measured in seconds, it should be in "somethings per second", or at least "so-and-so seconds to do such-and-such". (That's probably, what was meant there.) Units of measure are the only thing wrong with it. Other than that, it looks OK.

Hi,
I sometimes get confused when reading dates for BCE events since they run 'backward' ( like the camera specs) - a time span specified as
200 BCE to 100 BCE
just looks odd...

The minimum speed for the "shutter" to close is 30 seconds. The maximum speed for the "shutter" to close is 1/8000 of a second. (I'm not sure that the shutter for a digital camera is like an analog camera.) Based upon that, yes, the min and max are correct.

I think Stella740pl is correct, speed isn't measured in just "seconds".

The times quoted, 30 and 1/8000 seconds, are how long the "shutter" is open, not how fast it closes.

I understand why they put min and max the way they did, but it still sounds weird to me.

 

[fumei]

That is correct. The shutter speed itself - that is, the speed of the shutter mechanism is identical. The RESULT is 30 sec, or 1/8000. Technically speaking it should state the exposure range is 30 sec to 1/8000.

Just as a possibly interesting note. I took the longest exposure I have ever done with my digital camera recently. A single 93 minute exposure - actually 5,778 seconds.

That's interesting - did you really get any picture?

Back on the 'it sounds backwards' bit I still have to think twice about the North end of Australia being the tropical bit. I grew up in the UK with North analogous to Cold and Dark and that one headed south for the sun.

Obviously after the double take common sense cuts in and I understandf the geography. However the link between North<->Cold is very strong.

Stella,

Exposures of many minutes provide fascinating results when one uses a minimum f-stop of, say, f/16, instead of a maximum f-stop of f/1.4, during either a lightning storm...or on a clear night, it produces a lovely "spin-art" effect of the stars.
