EOS R8 - Underexposed images

Lorenz-photo — Thu, 20 Mar 2025 20:04:07 GMT

I bought a Canon R8 about a month ago, flawless until today. I’m in Prague and I was shooting around on the street with the RF 24-105 F4-7.1, the 500$ one. And I noticed that the exposure times I was using where unusual. I was shooting in the street with 7.1 aperture and 1/40 ss, and the image was underexposed. It was 1pm, I found it quite ridiculous. Im new to the camera so I don’t know the settings very well. I was wondering if I accidentally switched something on, or off. Please see if you can help, below are pictures of the house I’m staying in, the lighter ones are iPhone; the dark ones are camera, to show that the lighting is not that bad.

I had a problem with my T6S in that it was very easy to set an unwanted exposure compensation.

It should show up on the settings on the back of the camera. wrecked a days shooting at an airshow.

You can also go into the menu and reset *all* the settings if you want.

First of all what mode were you shooting in (M, Av, Tv, Fv & P) modes or Full Auto Green Square (A+) or any other automated shooting mode. Those pictures look like they’re underexposed by 2 stops. Was a speedlite (external) flash being used. Or were you just using ambient lighting. What was the ISO set to. There are 3 sides to the exposure triangle we only have 2 shutter speed and aperture. A specific time of day doesn’t always tell us the ambient lighting conditions. Where I’m at the clouds are dark and the sky is too. So a specific time doesn’t really help us. I would use ISO 400 or ISO 800 in my particular situation.

Lorenz-photo,

In addition to the questions that others have asked, I would add, what metering mode were you using with your camera?

Spot? Evaluative? If you were using spot metering, and your camera was pointed at a bright spot in your frame, your darker elements would be underexposed.

I was in Manual, I using iso 100 for minimal noise, you might be onto something with the speed lite control

I have it set to evaluative, which is supposed to be the auto version right ?

Were you even using a speedlite. If not that wouldn’t apply.
