Re: 5D3: No exposure compensation in manual mode.

"... the only response is a newly adjusted ISO to compensate and continue to provide this camera-defined “normal” exposure level."

 

I guess!  But I hardly call this "manual" mode.  Do you?  Smiley Frustrated

Re: 5D3: No exposure compensation in manual mode.

The key to why the exposure compensation is needed for bird photography for example, relates to what you said: "to fine tune the metering on the fly for a faked reading to tell the Auto ISO not to use the setting it suggests but a new value."

 

The shutter speed and aperture can't be used to adjust the exposure compensation as these have to stay within range to get a focused shot of a subject that can be moving quickly within and across the frame. 

 

The 'faked reading' is really just a bias that moves the histogram to the right to brighten up a small dark area, or darker details in the subject which is a bird that you have no control over. Therefore you only may get one chance for a shot or sequence of shots under poor conditions. Poor conditions could be bright back lighting, shadowing of the subject by some object, the subject distance making it relatively small compared to the whole frame.

The main thing being, that you need to bias the exposure to to overexpose some or most of the scene in order to get this one subject exposed well enough to bring out the detail you want.

Keep in mind that for this type of subject, the exact species of bird may not even be able to be identified if all you can't make out the details properly.

 

With practice a bird photographer can tell how much bias is needed for a starter setting that will increase the chances that the exposure of the subject will be within the ball park in the few seconds or less of the opportunity to take the shot, then post processing will be more successful, or even possible to get a useable result later.

I guess I see your point, but I'd maintain that the compensation is better done in post-processing, where you can brighten the dark areas with less risk of over-brightening the bright areas.

Three little words every serious photographer should know is, Raw and layers and masking.

Re: 5D3: No exposure compensation in manual mode.

Hi, been a long time since you posted. Did you ever get this fixed? I'm in the same situation, exactly the same reason you explained here. Want to set a specific f stop and speed and let ISO float but need to compensate the exposure for snowy owls.

Canon has added exposure compensation only fairly recently.  In Manual shooting mode, it only becomes available when ISO is set to Auto.  I do not believe that the 5D3 has that option.

WHich is ridiculous!  If you want to shoot in manual mode you are the exposure comp.  If you want auto, shoot in an auto mode. Simple.

Simply put If you do not like the feature, then do not use it.  End of story.

 

That is how it works.  If you have a problem with the feature, take it up with Canon.  I don't want to hear it!

 

You have the ability to allow the camera to control any one, any two, or all three legs of the Exposure Triangle.  What was missing from past cameras was the ability to dial in exposure compensation while the camera is controlling just ISO.

 

I think shooting in Manual with Auto ISO should be given a name, Exposure Priority.

There don’t read it. Nobody cares!
It is just a good thing you guys were not photographing in the 70s, 80s, or even the 90s. You would have never made it!

Exactly.  Nobody cares.  No one wants to listen to a dinosaur whine and complain about things he does not understand.  Like It said, if you have a problem with it, then take it up with Canon.  I did not design the cameras.  I did not petition Canon to add the feature, either.  

 

I don't want to hear it!  If you want to complain about it, then LEAVE my name out of it.  Thank-you.  RTFM, dude.
