Live viewfinder too dark when using off-camera flash

[Armstrong83]

I'm having trouble seeing my subject while shooting with flash. My settings are dialled in for off camera flash, this makes the viewfinder dark and I'm unable to get a good visual of my subject. Any ideas how a can see what I'm shooting while using flash?

Im assuming you have the camera set to manual exposure. If your camera is set to 1/125, f/5.6, ISO 100 and you’re indoors the camera is simulating the effect of your settings which is probably an underexposed shot, until flash fires. 

You need to locate the setting for Exposure simulation or Display simulation and disable it. Then the viewfinder preview is bright, but the exposure will be correct. 

If you use Canon Speedlites they communicate with the camera and the camera automatically disables the simulation when the flash is ready. Even works with wireless off-camera flash with Canon Speedlites.

Today I had the same problem. I was using an EOS R6 Mkii with Westcott FJ400s. When I returned from the shoot I checked and my OVF sim. view assist was off. I was shooting in Manual Mode at 1/200 sec., f8 , ISO200. What do you suggest I do? Thank you

The setting that you need to change is not OVF sim. view assist, but the one above that in the menu Display simulation and you'll need to set that to disable.
