Issue seeing tethered viewfinder image A7R ii w flash

Sean Kernan
Using flash and shooting tethered, if I set the exposure in Manual on my camera (Sony A7R ii) the image in the viewfinder or on the screen is too dark, but if I open up to see image, the file I take is overexposed. Thus useless for portraits.
What am I doing wrong?
This has never been an issue on Canon 5Dx.
Thanks

    Sounds like you need a modeling light?

    No, I am using a modeling light. If the camera's exposure is set according to the modeling light, the flash, when it goes off is much brighter, complete overexposure. But if the exposure is set from the flash meter the image in the finder is way under, too dark to see.

    Maybe I'm missing something but what you are describing sounds to me like you need stronger ambient light in the studio so you can see what you are doing through the viewfinder. That is the purpose of a modeling light which is why I mentioned that. Am I missing something?

    Are you using the viewfinder of the camera or live view in Capture One?
    Are you using lens that has a manual aperture and is stopped down?

    When using flash, exposure should be set for the flash, of course, not the ambient/modeling light.

    Until recently I have always worked with canon DSLRs. In that camera the aperture remains wide open until the shutter is pressed, letting in lots of light.
    When the shutter is pressed the aperture closes down to whatever it is set for as judged by a flash meter. The mirror swings up, the shutter opens and the flash fires. Then the mirror swings down and the aperture opens again.
    What I did not make clear is that the current camera is a Sony mirrorless.The whole procedure seems to be different. There is no mirror, the aperture once set doesn't seem to change for the exposure. So if the flash output is much higher than the modeling light...the file is blown out.
    If the modeling light were made brighterâ€"say from 250w to 5000wâ€"there'd be no need for a flash...and the whole soft box aparatus would probably go cup in flames.

    I understand that it's a mirrorless camera.
    It sounds like the EVF is showing you a live view rendition of the scene like cameras do in movie mode with the exposure settings applied.

    If you disconnect from the computer and shoot to the card does it still behave this way?

    Admittedly I'm not familiar with A7Rii cameras/settings, but I'd be looking in the menu's at the EVF settings.

    Go into your camera's menu for Live View. Turn Off "Setting Effect". This is the feature that allows the LV or EVF to display a representation of your exposure based upon the camera settings. With this turned off, the camera will try to show you it's best version of the scene. It does this by looking at the settings and changes to LV or EVF ISO, I think. Anyway, I use my A7RIII in studio with 250 watt modeling lamps with out issue. The Live View in C1Pro is fine though nowhere near as clean as the camera's Live View.

    Thank you! Just found something about this on youtube. I never would have guessed.
