R8 underexposed images on Tv mode

[JohnCJ]

Hello,

purchased my R8 in Dec 2023 and I was very excited. 
In Oct 2024 with my wife went Barcelona and few other European countries. 
I took R8 with RF 24-105 4-7.1,  RF 24/1.8 STM and RF 35/1.8 STM

The weather was nice and sunny, I set my R8 to Tv mode, 1/320, aperture wherever it falls, EV 0, AUTO ISO 100-200. 

I took 1,800 RAW images for the entire trip and to my surprise 90% of the images were underexposed and they look dim and dark when I imported the RAW files in Capture One PRO.

Even when I use R8 with Godox TT350c indoors, the images are too dark and contrasty. 
In the Picture Profile, I use Standard and lowered the Contrast to -3, still dark and contrasty images. 

My wife has a chepo Nikon Zfc and when we take photos at the same subjects, same lighting, same setting everything the same, her images are brighter, properly exposed and more pleasing to our eyes. 

Is there a setting or something I can adjust, so I can get properly exposed images in Tv mode and in general, so I can start loving my R8 ?

Do the JPEGS look the same way?

Have you tried DPP? It could be Capture One Pro.

Try taking an image in fully automatic mode and your TV mode and compare the exposure data.

Yes, JPEGS look the same. 
Just updated and tried DPP4, same - dark and contrasty.  The Histogram is on the left side.

I will try AUTO and Tv in 30 min, since I’m travelling at the moment.

Please post pictures in the forum. Depending on the mode the camera is set to E-TTL works differently. Godox speedlites are incompatible with the EOS R series. Mainly E-TTL and HSS don’t work together and cause underexposed shots. Or could be greatly overexposed.

The picture I took with flash were at a venue for our grandson birthday and there were many other children, I don’t think I can post pictures without the permission of their parents.  

But my bigger concern is the darker images on a bright and sunny day.

Well could you provide alternative flash pictures in the forum. Of other stuff around the house. Or censor out the faces in photoshop.

Pictures didn’t come out great, but the Histogram tells the tale.

Can you put RAW images in a file sharing service such as Google Drive. So we can look at the metadata attached to each picture. Were you taking these pictures with flash or without. If so were those pictures with a Godox speedlite they’re NOT compatible with the EOS R series.
