Exposure Compensation

[Eyron]

If I have a set shuuter speed (ie sync at 1/125 sec) and the correct
aperature reads say F9 .
But I need a lower F stop to limit depth of field.
Will minus 3 stops of exposure control alow this and give me a 3 stop larger
aperature?
Also what would my F stop be here?
Are there any drawback to use exposure compensation. ( ie noise etc.).

Yes - that is what "stop" means -

I'm not sure, but you can just use either aperture or shutter priority AE
mode and run the other up or down and find out. If you are in shutter
priority mode, then increase shutter speed until you get the f-stop you
desire. If you go aperture priority, just set the aperture you desire, and
if there is enough range, the shutter speed will match.

You aren't talking about exposure compensation; you are just setting normal
exposure. There is no drawback to any set or range of exposure combinations.
Just the effects of high vs low aperture and high vs low shutter speed.

The camera is in manual mode and is a Fuji S2 Pro.

If I understand you correctly, you say that you are fixing the F stop but
that you have already fixed the shutter speed, and now you want to change
the F stop to affect the depth of field. You would have to raise (higher
number) the F stop to increase the depth of field, and visa versa. But
since you have fixed the shutter speed, the exposure will not longer be
correct. I believe this is a digital camera? If this camera gives you a
RAW file output, then I think you can push or pull the picture +/- two stops
(at least I can with my Canon). If you want to do more than that, I'm not
sure. Also, if your camera does NOT give you a RAW file, then what you
propose may not or will not work.

It sounds like you should only post your message once, and don't do so
much cross posting, it is considered bad manner. Some of the groups you
included have little to do with your digital camera.

You should be able to change the "film speed" on your camera. Lower it
to force a larger stop and less depth of field or raise it for more depth of
field. ND (neutral density) filters also work and they work on digitals.

Just keep in mind that one 'stop' worth of exposure time is a factor of
two, while one stop difference is a factor of about 1.4 (or 0.7), since
exposure goes as f/stop squared. That is, going from f/5.6 to f/8 is
one stop difference, and would take a doubling of exposure time.

Why has this been posted twice in the same group?

Uh.. he's trying to get more "exposure" for his question? ;-)

Scattershot

I asked mult. groups.
I dont give a rats ass if you like it or not.
The exposure compensation does not work to achieve a larger aperature.
I tried it.

I thanks anyone who read my question and tried to answer.
One guy Gordon really read my question.
It was clear.

I totally agree Eyron! People like Gary Eickmeier
have nothing whatsoever to contribute so they spend
thier time poliecing the newsgroups. As if... But
you can at least tell this one was a butthead from
his name. There's a few others out there like Tony
Spandero, and Mark M. etc. doing the same sh*t. I
guess some peoples' lives are /just/ that dull.

Anyway Eyron, don't worry about it. Crossposts if
relevant are acceptable and don't cause anyone any
harm.
