The R10 Advanced Users Guide starting on page 142 (attached is part of page 143) explains setting EC while using Auto ISO in Manual mode.

Hi Mike,

With the EOS R10 there are only two dials on the camera body, the main dial and quick control dial. In manual mode by default the main dial controls shutter speed and the quick control dial controls aperture value. There are four ways to change exposure compensation when shooting with AUTO ISO in manual mode on the EOS R10.

1. Tap the exposure compensation scale on the LCD screen and use the main dial, quick control or the +/- buttons on the screen.
2. Use the control ring on RF lenses, or control ring mount adapter
3. Customise the quick control dial so that instead of aperture control it is exposure compensation. Though then you need to decide how to change aperture. Go to customise dials menu to find this.
4. Use a custom button configured for exposure compensation. While the button is pressed and held turn the main dial to change compensation. The following buttons can be assigned this function; AF-ON, asterisk, depth of field preview, SET. 

Hope that helps.

Hi Mike,

Here's what I did with my EOS R10.

Firstly I changed the SET button to allow me to change exposure compensation while it was held down as I described above in point 4. 

Now I took these HDMI screen captures of the camera. They are slightly different in that you can't use touch control on a HDMI screen connected to the camera.

The first of the three shows the camera in manual with auto ISO and no compensation. 

Second frame shows +1 exposure compensation has been added.

Third frame was captured while holding the SET button pressed. You can see that the orange main dial icon is now next to the exposure compensation scale, not shutter speed, indicating that when the main dial is turned the exposure compensation will be adjusted. 

In the first two captures I was not touching any buttons, so the ISO just says AUTO with no value. In the last shot the ISO shows AUTO and 1250, this is because at this point I was also holding the SET pressed. 

The eagle-eyed will notice my framing moved and focus is hit and miss - I'm handholding the camera with one hand while operating the computer to capture the screenshots and didn't use a tripod.

Mike,

You probably know, in Manual Mode, the only thing you can compensate is the ISO, and that's only if it's in Auto, as yours is.

From what I understand, the way you set that is to half-press your shutter button, and rotate the Quick Control Dial. I think that's located on the top.

Instructions for this can be found on page D185-062 of your manual.

Steve, I tried that, and I see the ISO value changing (even though it says Auto ISO next to the numbers) , but there's no indication in the light expoure meter as to how much/little compensation there is.

Your thoughts?

Thanks,

Mike

You wrote, "Steve, I tried that, and I see the ISO value changing (even though it says Auto ISO next to the numbers) , but there's no indication in the light expoure meter as to how much/little compensation there is."

I think that's normal. It will always say, "Auto". Make your adjustment and half-press your shutter. The gauge will tell you where you are. Leave it there, or make another adjustment and do the half-press of the shutter again.

Fantastic!!!   "You da man!"

I found a fifth way to change exposure compensation with manual exposure and auto ISO.

The M-Fn button is normally used for the Dial function settings. I forgot that this includes exposure compensation, or can do.

Activating exposure compensation on the Canon R10 while in Manual mode with Auto ISO involves a few steps. Here's how you can do it:

1. **Set the Mode to Manual (M):**
- Turn the mode dial on the top of the camera to "M" for Manual mode.

2. **Enable Auto ISO:**
- Press the "ISO" button on the top of the camera.
- Use the dial or the touchscreen to select "Auto ISO."

3. **Activate Exposure Compensation:**
- Press the "Q" button to enter the Quick Control screen.
- Use the dial or the touchscreen to highlight the exposure compensation icon (a plus/minus symbol).
- Use the main dial (usually the dial near the shutter button) to adjust the exposure compensation value. You can move it towards the positive side to make the image brighter or towards the negative side to make it darker.

Note that in Manual mode, exposure compensation affects the Auto ISO setting. The camera adjusts the ISO to achieve the desired exposure based on your compensation settings. This allows you to manually control the aperture and shutter speed while letting the camera automatically adjust the ISO to maintain proper exposure according to your compensation adjustments.

Thank you very much for your input. Your's is the second time that this solution has been offered, and I really appreciate your input.
