A stupid question.....

Yes
...regarding metering modes.

Am I right in thinking, that if you ignore all other variables (light slightly changing between shots etc etc)...

If I was to set up a camera and take the following shots :

Using Spot Metering in Av or Tv : f/8, 1/125, ISO100
Using centre weighted average metering in Av or Tv : f/8, 1/125, ISO100
Using evaluative metering in Av or Tv: f/8, 1/125, ISO100
Manual : f/8, 1/125, ISO100

Like I say, discounting any other variables, like the sun setting (or the camera moving etc), or whatever. Am I right in thinking that the above shots would all be EXACTLY the same?

And that it's the metering mode that ONLY determines the settings to be used (IE aperture/shutter speed etc, in the relative modes), not determining, say that the corners of the shot will be lighter in such a mode, or that the shots will look slightly different.

Does that make sense?
 
Dunno about stupid.....

But complicated :thinking:

But seriously,
why don't you just try and find out what happens, someone on here will lend you a camera if you need one (y) ;)
 
Short answer - provided that you've metered correctly for the scene, regardless of what metering mode you used, then the shots would all look the same.

That's if I've understood the question, and I'm not sure I have. :D
 
not sure if im right about this but i was under the impression that metering was used to tell u the recommended settings there for if ur settings are the same the pic will be the same surly???
 
LOL

Yeah it's basically about metering.

So it's irrelevant what metering mode you use.....if the resulting settings are the same, then the shots will all be the same.....
 
Well provided you've metered correctly - yes they would. Evaluative metering takes readings from little separate segments all over the focusing screen and the onboard software computes the best exposure from them all. It's pretty good most of the time but it can get it wrong.

With spot metering you don't get any assistance -it's up to you to spot meter on the right bit{s) If you photographed a black car against the sky and spot metered on the car, then obviously the sky would be well blown out.
 
I'm not sure if I've understood you correctly. :thinking:

Have you metered the scene with the different meter modes and got the same readings, or have you set the camera to the settings you mentioned disregarding the readings from the light meter modes?

Or is it just in theory?

The different metering modes may give you different readings dependent on the scene. An overly bright or dark centre of the scene may give a different reading using the centre weighted or spot metering modes to the evaluative mode. That is why they are there, for difficult lighting situations. If the scene has average levels of light across the scene, there may be little or no change to the exposure reading shown by the different meters. If that reading is f/8, 1/125, ISO100 in the different modes, then the resulting image will be the same. Spot or centre weighted normally give different readings to evaluative, especially the spot meter.

If it's digital you've got, it's easy enough to test for yourself. ;)
 
Sorry! I wasn't quite up to par with my wording last night :D

Yes, it was a hypothetical question.

If I was to use either of those metering modes, and the resulting readings were the same (ignoring where i'm metering from etc), then would the shots be exactly the same.

It was something that's been going round in my mind for ages (one of those questions that bug you when you're going to sleep). I knew the answer, but just wanted it confirmed :D

So, yes, the resulting image would be the same.

Told you it was a stupid question!
 
(y)
Same settings = same results. No matter how the settings were achieved.

Take pics of a grey card and see what happens

It really is as simple as that. The results might be good or they might be bad, but they will be the same.
