EOS R6 Mark II viewfinder and screen brightness issue

[Stef71]

I was taking pictures in low light with my R6II pushing the boudary and while they looked fine in the viewfinder and on screen (both while taking the pictures and in viewing them after they have been taken) Back home on my computer they are way too dark (the computer screen is calibrated so that should be just fine, also I tried viewing them on another computer to be sure)  I tried to set the brightness for both to match what I got on the computer and I had to go back to setting 1 to get anywhere near (and it's still a bit brighter though). I know I should have used the histogram but sadly I didn't 'cous it works fine in 'normal' light conditions. Is there another setting I should have checked or is this a real issue? 

[Stef71]

The issue is not the file itself, it is too dark and I'm aware of that, but the camera shows it off as acceptable dark as all the rest says way too dark.

Stef71,

With settings of f/13, and a shutter speed of 1/500 to 1/1000 with a teleconverter in low light, I would expect dark pictures.

I don't know how the R6 MII behaves, but on my camera (a T8i), I can't playback images in my viewfinder.

It's possible that you have the brightness on your LCD screen set too high.

Do you mean that the rear LCD shows it as OK when you review it on the camera?

Does the camera histogram match what your computer editing software shows?

[Stef71]

The histogram does look the same in both, but as I didn't check it while shooting I didn't see it was going to be too dark as the display tels a different story (on display lt looked acceptable both while shooting and in play back) The display and viewfinder settings for brightness were both standard 4 (out of 7). I tried to get the pictures to match brightness on computer but putting the settings all the way back to 1 still a bit brighter and thats (I think) way too much difference to be normal

And you had Exposure Sim selected?

[Stef71]

Hmmm I have to check that. But that shouldn't affect viewback though ...

[jrhoffman75]

If you have the OVF simulation selected the EVF doesn't reflect the scene conditions.

I ran a test on my R6M2 and if I lower the exposure comp by -3 the EVF darkens and the playback image looks the same.

Im gonna check that (later as I'm not at home right now)

"I didn't see it was going to be too dark as the display tels a different story ..."

The LCD is not the same as your computer monitor. Both have settings you can adjust.

Have the settings on camera display set way back at 1 and still much lighter than on computer, the difference is just too much
