A question about exposure compensation in manual mode
Jan 17, 2023 07:22:55 #
Although the guru didn't say it I think he meant with auto ISO on. Manual with auto ISO isn't really manual but many consider it as manual and use EC a lot.

EC Exposure Compensation. Adjusts the light meter sensitivity either up or down. In other words it will offset the center reading of the meter. So if your meter is say offset by 2/3 , then when centered it is really 2/3 higher/ lower which ever you choose. So your camera thinks it' centered but exposure wise it is not. So this allows you to set it for a specific scene say a bright off subject background which would normally result in a high meter reading of the scene thus under exposing the subject. Adjusting the EC down in this case would give you a center reading but in fact expose at a higher level and give correct exposure to subject. What it adjust in manual mode would be camera specific. So it is another tool you can use . Your choose on which tool you want to use. Do I have this correct?

If you are shooting with Auto ISO in manual mode, then EC adjustment affects the ISO, and will brighten or darken the image. If shooting JPG, this can be used to avoid blown highlights or crushed shadows.
It was (perhaps is) long a subject of controversy. With mirrorless cameras, the EC adjustment also affects the brightness of the image in the viewfinder. For many years, photographers were requesting that the camera mfgs allow EC adjustment in manual mode. There was a lot of "we don't need it" arguing from more conservative photographers, but gradually EC adjustment in manual mode caught on. All of my cameras (Nikon, Olympus, Panasonic) allow it.
Yay!!!

NO. At least on Sony and Nikon camara's it will not work.
In Manual you can change the exposure using the iso, shutter speed, or Aperture. My wheel on the back of my Sony is set to iso, I can, in manual, change my exposure quickly by turning the wheel.

Bill...this is incorrect. I have successfully used Exposure Compensation in Manual Mode on a D200, D300, D300s, D500, D810, and D850. All are made by Nikon. I have a D90 converted to IR, also Nikon, but do not know if it works on that camera, because I've never tried and have no need to do so. I never use Auto ISO, because it was dangerous with my older cameras and my routine doesn't require it. My expectation is that it should work just fine in applying the desired bias to the meter indication, but I can't say for sure because I haven't done it.

Ysarex...I answered the OP's question quite correctly. If he cannot deduce from his camera'sinstruction manual whether EC in Manual works on his camera, a simple one or two minute experiment will reveal the answer. Just try it, with an exaggerated amount of correction, and see what it does to the meter indication. It's how I figured it out. Not much in the world could be easier than that.

This isn't something I'd feel called to do, but a quick experiment should reveal if it works. Why is this always so difficult when it comes up?

Bill's one word answer, NO, to the OP is correct. He answered the OP's question. The OP asked: "....can EC correct selected manual settings to other settings?" [my bold] I have a Nikon Z7 and have owned other Nikon cameras. No Nikon camera or any other brand camera can alter a manually selected shutter speed, f/stop, or ISO setting.

No you didn't. Here's the OP's question again: "So my question is can EC correct selected manual settings to other settings?" [my bold]
It's a clear and simple question. I have a Nikon Z7. If I manually select the shutter speed, f/stop, and ISO the EC control can not alter those settings. Answer is no.

The OP's question was specific. Here it is again: "So my question is can EC correct selected manual settings to other settings?" [my bold] I personally have Nikon, Canon, Fuji and Leica cameras. If I manually select (OP's words) the shutter speed, f/stop, and ISO none of my camera's EC controls can alter those settings to other settings. The answer to the OP's question is an unequivocal no.

Where in the OP's question does he ask about the meter indication? Do I need to repeat the question again?

There is no need for experiment. I never use the EC but I know exactly how it works. There is never a doubt of how EC works on my camera. But it seems so many having problems figure this out. However, in this case the OP just question what the guru said. He knew how his camera behaves.
It was the guru perhaps wasn't clear or didn't know.

Correct

That is correct. When using EC in manual mode, auto ISO must be enabled. in that case manual mode become a type of "semi semi-auto" mode where two thirds of the exposure triangle is set manually.
In aperture and shutter priority modes with auto ISO enabled only one third of the exposure triangle is set manually.

Interresting question. Since I don't use it often I experimented on mine to see. As some have pointed out it's likely different for differnt brands or models but for mine, a Z7ii I found the following:
In manual mode I took three shots with the Auto ISO set to off. The three shots were taken with +/- (EC) set to 0, +0.7 and +1.3. The exposure indicator showed 0, -.7 and -1.3 for the respective shots but the images looked the same. So in this case all that was effected was the meter reading.
I did this again in manual mode but with Auto ISO set to on but with the same base ISO setting. This time the ISO increased as the EC was adjusted upward (+0.7 & +1.3), the exposure indicator remained as ~ 0 and the images were successively brighter. In this case the ISO was adjusted to yield brighter images. I'm sure the other P, S and A exposeure modes operate similarly except that I suspect Shutter and Aperture would not be altered in those modes.

EC combined with Auto-ISO is very useful. Set your speed and aperture and let Auto-ISO get the "right" exposure. But if the "right" exposure is wrong (e.g., dark bird on bright water), changing the EC can correct the exposure without changing your speed or aperture settings. That's the way it works on Nikon. To my frustration, not on Fujifilm.

Actually it's not likely different. In fact, in the case of the OP's question, consistent behavior is the rule across different camera makes/models. They all respond the same: changing the EC value will not change a manually selected shutter speed, f/stop or ISO setting to some other setting. Your test confirmed the Z6II complies.
