A question about exposure compensation in manual mode (Page 5): :sm24: Depending on brand and model, EC in Manual can adjust ISO, especially if it is in Auto.

The only way EC works in manual mode is if the ISO is set to auto, then the EC adjusts ISO.

Yet this point seems to have escaped 90% of the posters here.

No camera would adjust the shutter speed, the aperture or the ISO if it's in manual and auto ISO is off. The difference mainly that some camera allows you to set the EC but only bias the meter and some doesn't allow you to do that.

Nope, EC on some cameras can adjust ISO in Manual mode ONLY if the ISO is in auto.

There is a single answer to the question the OP asked. For all camera makes and models the answer is an unequivocal no.
The EC control on all camera makes and models can not change "selected manual settings" to other settings. If there's an exception somebody ID it.

The only EC that really works in that situation is the one in the raw converter. Move the exposure slider and voila you actually can compensate for some overexposure and a lot of underexposure.

But not with more or less exposure. That slider is misnamed and now this drifts off topic. It's important to remain mindful that exposure = the amount of light reaching the sensor per unit area and that is a function of only scene brightness, time (shutter), and f/stop. The result you get from exposure is unique to exposure and can't be compensated for by altering the lightness of the final image through other means.

Yes but in the case of auto ISO it doesn't change the exposure either. In fact the exposure slider in raw converter works more like the ISO setting. And it doesn't change the exposure. It compensates for some degree of exposure error to give you decent image. And thus it's the real exposure compensation setting.

The basic idea here is that you select and lock in both the aperture and shutter speed and then you allow the camera to adjust exposure by floating ISO up or down as needed. Some cameras allow use of exposure comp in this configuration and others do not. For those cameras that do allow the use of exposure compensation, dialing in a plus or minus EV value would only effect the setting the camera sets for ISO as the aperture and shutter speed are both locked in place.

While EC in manual mode seems like an oxymoron , some cameras offer it.
The one argument I can think of in favor of it would be If you Use EC regularly in other modes, there is really no harm in allowing it in Manual MODE. But personally, if I am in manual mode and need to adjust exposure I would rather choose Aperture or Shutter Speed myself, depending on conditions.

There is no camera that will change selected manual exposure settings to other settings via the camera's EC control -- not a one.

That's correct. However ISO will most commonly alter the raw data and has the potential to permanently clip highlights.

But it's not a camera control.

I can control ISO on my cameras.

Been spending some time with Rip Van Winkle? We're long past that. Fuji was one of the last hold outs on allowing EC to adjust auto ISO with the camera in M mode. They caved in 2016. Seven years is a long time in the digital camera world. I can't think of any current or recently current camera that doesn't provide the feature to allow the EC to alter auto ISO with the camera in M.

That said the OP specifically wanted to confirm that no camera's EC control could change a selected manual setting to some other setting. And we can confirm that. No camera's EC control will change a selected manual setting.

So can I. In response to BebuLamar's post, what I said wasn't a camera control is the exposure slider in a raw converter.
