Trying full Manual with Auto ISO. Dial changes shutter speed and pressing exposure button has dial change aperture. Is there any way to also have exposure compensation control?

You're not in "full manual" if you're using Auto ISO.

I think if you change the exposure by aperture or shutter speed . . . It would cause the ISO to change because it's in "auto" so I think the answer to your question is "no" . . . Try it and see what happens . . .

You are using Manual Exposure. That controls aperture and shutter speed using the appropriate dials.

ISO is not exposure!

Auto ISO is controlled by the light meter, which is affected by Exposure Compensation. Setting EC to a plus value will raise the ISO while a minus value will lower ISO. That does not change exposure, it only changes how bright the image is for the amount of exposure you manually set.

Don't be put off by comments about your reference to "full manual"! Some folks here don't consider "M" to be Manual if you use it with Auto ISO.

To your question: Not sure about your D5500, but on my Nikon D5300, when set up for back-button focus, you change exposure compensation with entries on the Information Screen. Hope this helps.

While I understand and like your explanation with respect to the light meter function and EC's affect, ISO is referenced as being part of the exposure triangle, so the confusion can be understood.

Exposure is defined as how many photons hit the sensor. ISO does not change the exposure. But ISO does change how bright the captured image is for a given amount of exposure, which is why ISO and exposure are a triangle.

That is an important relationship and you are correct that it is commonly misumderstood by.many.

Thanks again!

BTW, enjoy your damp and cloudy weather in the 30's! Wish I was there!

Think of ISO as Signal to Noise ratio. Higher ISO means higher Noise for the same signal.

Manual is manual, and that is what it means. It does not mean automatic.

Is this request a result of John Gerlach's thread?

It's obviously related but I think exposure compensation is a completely separate function from the ISO/Aperture/Shutter Speed controls. My D5500 seemed to take slightly over-exposed shots for my taste so I dialed down the exposure compensation two tick marks and it works across all modes. I don't see the point of trying to control it for each shot along with ISO, aperture or shutter speed as it would be redundant to, or interfere with, those functions. I think its simply a "fine tuning" feature you want to set once, and forget.

That's all well and good to set and forget unless you're in a situation where light changes due to quick changes in shot direction...wildlife for example.

Understood. However, in a quickly changing light situation, you'd change your aperture, speed or even ISO; you wouldn't change the exposure compensation. When I said my camera tended to overexpose for my tastes, I meant it overexposed for all modes and all situations. Yes, I could easily compensate in Manual mode but I often shoot in Aperture or Shutter Priority where the camera choses a setting and I want it to set itself to shoot a tiny bit darker, in those modes. Since this topic came up, I wonder if other UHHers might discuss how they use exposure compensation; maybe I'm missing something.

Not in manual, and there is no need for that, because you're already doing it (manually)!!
